Usine d'extrudeuse à double vis vs société commerciale: Comment faire la différence

Points clés à retenir

• D'après mon expérience, le marché de gros des extrudeuses à double vis couvre une énorme gamme de prix, de la région sub-américaine $2 unités de nouveauté de laboratoire à grande échelle pour des ensembles de production entièrement configurés au-dessus des États-Unis $200,000, donc je traite n'importe quelle citation comme dénuée de sens jusqu'à ce que je la lie au diamètre de la vis, sortir (kg/heure), et la puissance du moteur (kW) — Liste des extrudeuses à double vis de laboratoire en plastique Accio en gros (2026).
• J'adapte la géométrie de la vis au travail avant d'acheter le prix: Vis jumelées co-rotatives à engrènement pour mélange et mélange maître, Extrudeuses coniques à double vis contrarotatives pour lignes d'extrusion de tuyaux en PVC souple et rigide avec découpe à l'emporte-pièce — Ligne de granulation conique à double vis en PVC JWELL Machinery (2024).
• Les noms de modèles en gros codent généralement le diamètre de la vis, et une bande d'approvisionnement pratique s'étend d'environ 10 Unités de banc kg/h jusqu'à ~150 kg/h d'extrudeuses de mélange, évoluant bien au-delà 4,000 kg/h sur le marché de l'occasion avec des marques comme Berstorff, KraussMaffei, et Maris — twinscrewgranulator.com (2024); Euro-Machines (2024).
• Le marché secondaire est suffisamment profond pour être une véritable stratégie, pas une solution de repli: une seule plateforme répertorie plus de 74,746 produits d'extrudeuse à double vis d'occasion, avec des ensembles coniques en PVC d'occasion cotés près des États-Unis $25,000 — Fabriqué en Chine.com (2024).
• Je sépare toujours le prix unitaire du coût total au débarquement. L'autocollant (Par exemple, un 100 kg/h, 80 Unité kW construite en Inde près de Rs 15,00,000) ce n'est que le début une fois que j'ajoute du fret, devoirs, conversion de tension, et mise en place — Nouvelles machines en plastique, Bahadurgarh (2024).
• Le type d’activité du fournisseur change complètement la négociation, so I confirm whether I'm dealing with a manufacturer/factory, une société commerciale, ou une société du groupe, et si une véritable capacité OEM/ODM existe — Filtres de fournisseurs Made-in-China.com (2024).
• Je considère les certifications comme une exigence de contrôle, pas un bonus, vérification CE, ISO9001, BPF (pour lignes pharmaceutiques), et UL par rapport à la machine réelle plutôt qu'au catalogue — Taxonomie des certifications Made-in-China.com (2024).
• Pour les acheteurs de laboratoire et de produits pharmaceutiques, Je confirme dès le départ les spécifications pertinentes pour le processus: un typique 25 mm, 7.5 kW, 50 unité expérimentale kg/h avec automate et dégazage sous vide, et un 50–600 plage de fonctionnement tr/min pour pharma R&D — Liste des laboratoires Accio (2026); Liste des usines d'extrudeuse à double vis de laboratoire en Chine (2024).
• Les catalogues de décisions ignorés sont ceux que je planifie en premier: MOQ, Incoterms, étapes de paiement, inspection de contrôle qualité avant expédition, et un cadre clair entre nouveau et utilisé et OEM/ODM que le reste de ce guide détaille étape par étape..

Ce que la vente en gros d'extrudeuses à double vis signifie réellement pour les acheteurs B2B

Lorsque les acheteurs me posent pour la première fois des questions sur la vente en gros d'extrudeuses à double vis, ils supposent souvent qu'il s'agit simplement d'une réduction sur une seule machine. D'après mon expérience, le terme décrit quelque chose de plus large: un modèle d’approvisionnement construit autour de relations de volume, accès direct en usine, et des conditions commerciales négociées plutôt que des prix de liste de catalogue. Understanding that distinction is the difference between paying a fair landed cost and overpaying for a reseller's markup.

Vente en gros, vente au détail ou vente directe en usine

Je trouve utile de séparer trois modèles d'achat qui se confondent sur ce marché:

• Vente au détail. Vous achetez une seule unité au prix publié ou presque publié, généralement par l'intermédiaire d'un distributeur ou d'une société commerciale. Pratique, but you carry the intermediary's margin and have little leverage on specifications.
• De gros. Vous vous engagez sur le volume, répéter les commandes, ou une ligne configurée, et en échange vous négociez le prix unitaire, étapes de paiement, et délai de livraison. Un fournisseur en gros d’extrudeuses à double vis s’attend à une discussion, pas d'acceptation d'un prix autocollant.
• Directement de l'usine. Vous passez un contrat avec le fabricant réel plutôt qu'avec une société commerciale. Cela donne généralement le coût unitaire le plus bas et le plus grand contrôle sur la construction de la vis et du baril de l'extrudeuse., mais cela vous transfère davantage de responsabilités en matière de contrôle qualité et de logistique.

Made-in-China.com's own supplier filters make this hierarchy explicit, fabricant/usine distinctif, société commerciale, et types d'entreprises de sociétés de groupe, avec capacité OEM/ODM signalée séparément (Filtres de recherche pour extrudeuse à double vis Made-in-China.com, 2024). Je vérifie toujours cette classification en premier, parce que cela me dit si je parle aux personnes qui ont réellement coupé les vols ou à un intermédiaire.

Qui achète réellement en gros

Le canal de gros n’est pas réservé aux commerçants. Les acheteurs avec lesquels je travaille se répartissent en quatre groupes, chacun avec des priorités différentes:

• OEM et constructeurs de machines qui intègrent une extrudeuse de mélange dans une ligne de production d'extrusion clé en main plus grande et qui ont besoin de, alimentation configurable.
• Transformateurs et formulateurs de matières plastiques produire un mélange maître, polymères chargés, ou composés d'ingénierie, qui se soucie le plus du rendement de l'extrudeuse en kg/h et de la stabilité du couple.
• Revendeurs et distributeurs régionaux stocker une gamme de granulateurs à double vis pour leurs propres clients.
• Recycleurs faire fonctionner une extrudeuse de recyclage de plastique où la tolérance à la dévolatilisation et à la contamination compte plus que le débit maximal.

Chaque groupe négocie différemment. Un recycleur s'efforcera d'améliorer la capacité de dégazage sous vide et la robustesse du changeur de tamis.; un OEM se soucie des délais de livraison reproductibles sur plusieurs unités.

Comment le commerce de gros modifie les prix, MOQ, et effet de levier

Les prix de gros dans cette catégorie couvrent une gamme extraordinaire, c'est exactement pourquoi le contexte est important. Les annonces sont diffusées sous les États-Unis $2 par unité à volume élevé jusqu'à plus de US $200,000 par set pour les systèmes industriels entièrement configurés (Liste des extrudeuses à double vis de laboratoire en plastique Accio en gros, 2026). Cette répartition reflète tout, des petits composants consommables aux machines de production complètes., so a quoted "wholesale price" ne veut rien dire tant que vous ne connaissez pas l'unité de vente.

Comme points de référence que j'ai trouvés crédibles: une construction indienne 100 kg/h, 80 L'extrudeuse à double vis semi-automatique kW est cotée autour de Rs 15,00,000 par pièce (Nouvelles machines en plastique, Bahadurgarh, 2024), tandis que les extrudeuses de tuyaux en PVC coniques à double vis d'occasion se vendent près des États-Unis $25,000 par ensemble (Made-in-China.com a utilisé la vente en gros d'extrudeuse à double vis, 2024). Votre effet de levier augmente avec l'engagement de volume, volonté de standardiser la configuration, et flexibilité sur les délais. Cela tombe lorsque vous avez besoin d'une version personnalisée unique dans un délai serré.

Le paysage mondial de l’approvisionnement

Les extrudeuses bivis servent les plastiques, médicaments, transformation des aliments, et produits chimiques en raison de leur précision, versatilité, et efficacité (Haut 20 Fabricants d'extrudeuses à double vis, 2025). Cette demande prend en charge deux grands niveaux d'offre. D’un côté se trouvent les usines chinoises offrant des prix agressifs et une grande configurabilité., fréquemment certifié CE, ISO9001, BPF, et normes UL (Taxonomie des certifications Made-in-China.com, 2024). De l’autre, des marques européennes et japonaises haut de gamme, dont les machines dominent le marché de l'occasion à haut rendement. Euro-Machinery's inventory alone spans brands such as Berstorff, KraussMaffei, et Maris, avec les sorties de 100 kg/h à 4,000 kg/heure (Catégorie extrudeuses bivis Euro-Machinery, 2024).

Il existe également un marché secondaire important: Made-in-China.com répertorie plus de 74,746 Vente en gros de produits d'extrudeuse à double vis d'occasion, ce qui me dit que l'équipement d'extrusion d'occasion est une voie d'approvisionnement viable, pas une option marginale (Made-in-China.com a utilisé une extrudeuse à double vis, 2024).

Comment fonctionnent les extrudeuses à double vis et pourquoi la configuration est importante

Avant d'évaluer un devis de gros pour une extrudeuse à double vis, Je veux comprendre ce que l'on demande à la machine de faire mécaniquement. Le prix n'a de sens que lorsque la configuration correspond au matériel. Laissez-moi donc passer en revue les principes fondamentaux de la façon dont je les explique à une équipe d'approvisionnement qui n'a jamais spécifié d'extrudeuse auparavant..

La mécanique des vis à engrènement

Une extrudeuse à double vis place deux vis côte à côte dans un baril en huit.. Dans une conception à double vis engrenée, le vol d'une vis balaie le canal de l'autre. Cette action d'auto-essuyage est ce qui différencie ces machines des extrudeuses monovis.: le matériau ne peut pas simplement rouler avec une seule vis, donc il est continuellement transféré, cisaillé, et renouvelé. Le résultat est un transfert bien plus positif et un mélange nettement meilleur..

Trois fonctions principales: Convoyage, Mélange, Dévolatilisant

Chaque processus à double vis que j'ai spécifié revient à équilibrer trois tâches le long du canon.:

• Convoyage. Les éléments à vis avant déplacent le matériau de l'alimentation à la filière à une vitesse contrôlée, réglage de la sortie de votre extrudeuse kg/h.
• Mélange. Les blocs de pétrissage génèrent le cisaillement distributif et dispersif nécessaire à la dispersion des charges, pigments, ou des additifs dans le polymère fondu.
• Dévolatilisant. Les ports de dégazage sous vide évacuent l'humidité, monomères, et volatiles, ce qui est essentiel pour une extrudeuse de recyclage de plastique manipulant des matières premières contaminées ou hygroscopiques.

Les unités de laboratoire pharmaceutique illustrent avec quelle précision cela peut être réglé, opérant sur 50–600 plage de régime pour le traitement expérimental (Liste des usines d'extrudeuse à double vis de laboratoire en Chine, 2024).

Pourquoi deux vis surpassent une pour la composition

Quand la tâche s’aggrave plutôt que de simplement fondre, Je recommande presque toujours un jumeau plutôt qu'une seule vis. La géométrie engrenée dissocie l'alimentation de la génération de pression, afin que la machine puisse se nourrir de faim au niveau de la gorge et laisser les éléments en aval contrôler le remplissage et le cisaillement indépendamment. Cela donne à une extrudeuse de mélange un temps de séjour constant, meilleur contrôle de la température, et la possibilité d'ajouter un alimentateur latéral pour les charges ou les fibres à mi-chemin dans le canon. Une seule vis ne peut tout simplement pas égaler cette flexibilité pour la fabrication de mélanges maîtres ou de composés chargés..

Le rôle des éléments modulaires à vis et des blocs de pétrissage

La fonctionnalité que je considère comme la plus importante commercialement est la modularité. Sur une machine moderne, la vis est un ensemble d'éléments de vis individuels clavetés sur un arbre à couple élevé, et le canon est une série de segments. Cela signifie que le même matériel peut être reconfiguré pour un matériau différent en modifiant la séquence des éléments de transport et des blocs de pétrissage.. Deux spécifications entraînent la capacité ici:

• L/D ratio — le rapport longueur/diamètre. Un L/D plus long permet plus de zones de traitement pour le mélange et la dévolatilisation.
• Diamètre de vis — les gammes de produits en gros utilisent généralement le diamètre de la vis comme convention de dénomination, avec des résultats s'étendant à peu près 10 kg/h à 150 kg/h sur une gamme de modèles (spécifications du produit twinscrewgranulator.com, 2024).

Quand j'évalue un devis, Je demande si la vis et le canon sont modulaires et quel L/D la construction fournit, car ceux-ci déterminent la durée pendant laquelle la machine reste utile à mesure que votre gamme de produits change.

Vis jumelées co-rotatives, contre-rotatives et coniques

Le choix le plus important dans toute décision de vente en gros d’extrudeuse à double vis est la disposition des vis.. J'ai vu des acheteurs se concentrer sur le prix et la puissance du moteur en kW tout en ignorant cela., puis découvrez que la machine n'est pas adaptée à leur polymère. Les trois familles ci-dessous ne sont pas interchangeables; chacun est optimisé pour un travail différent.

Vis parallèles co-rotatives pour le mélange

Dans une double vis co-rotative, les deux vis tournent dans le même sens. C'est le cheval de bataille de la préparation et de la fabrication de mélanges maîtres, car il offre des résultats élevés., cisaillement bien réparti et excellent auto-essuyage. Si votre application concerne des composés d'ingénierie, polymères chargés, mélange maître de couleur, ou extrusion réactive, c'est presque toujours par là que je commence. Il s'associe naturellement au dégazage sous vide et à un alimentateur latéral pour l'ajout de filler en aval..

Vis contrarotatives pour travaux en PVC et sensibles à la pression

Dans une double vis contrarotative, les vis tournent dans des sens opposés, créant une action de calandrage entre eux et plus douce, cisaillement inférieur avec un fort transfert positif. Ce profil convient aux matériaux sensibles à la chaleur et aux traitements sensibles à la pression, c'est pourquoi c'est un choix standard pour le PVC. Le cisaillement inférieur protège le polymère de la dégradation thermique tandis que le déplacement positif crée une pression stable pour la matrice..

Vis jumelées coniques pour tuyaux et profilés en PVC rigide

Les extrudeuses coniques à double vis utilisent des vis qui se rétrécissent d'un diamètre plus grand à l'extrémité d'alimentation à un diamètre plus petit au niveau de la filière.. La zone d'alimentation plus grande améliore l'absorption de poudre de PVC à faible densité apparente, tandis que la géométrie convergente comprime et crée une pression efficacement. Cela fait de la conception conique la réponse traditionnelle pour les lignes et profilés d'extrusion de tuyaux en PVC rigide.. Les unités coniques contrarotatives sont également utilisées pour la granulation du PVC souple et rigide avec découpe et refroidissement en aval. (Ligne de granulation conique à double vis en PVC JWELL Machinery, 2024).

Adaptation de la configuration au matériau et à l'application

Pour rendre cela pratique, voici la comparaison que je présente aux acheteurs lorsqu'ils réduisent leur liste restreinte.

Configuration	Rotation des vis	Profil de cisaillement	Applications les mieux adaptées	Matériaux typiques
Parallèle co-rotatif	Même direction	Haut, distributif et dispersif	Composition, mélange maître, extrusion réactive, recyclage	PP, PE, Pennsylvanie, composés chargés et techniques
Parallèle contrarotatif	Directions opposées	Faible, calandrage doux	Pelletisation de résines thermosensibles, travail sensible à la pression	Composés PVC, polymères thermosensibles
Conique contrarotatif	Directions opposées, conique	Faible, avec une forte admission et une forte montée en pression	Tuyau et profilé en PVC rigide, Granulation du PVC	Poudre PVC rigide et souple

Ma règle de base: si vous dispersez des additifs dans un polymère thermiquement stable, spécifier la co-rotation; si vous travaillez du PVC ou un autre matériau sensible à la chaleur, regarde à contre-rotation; et si vous utilisez un tuyau ou un profilé en PVC rigide à partir de poudre, l'extrudeuse conique à double vis est spécialement conçue pour vous. Une fois la configuration réglée, spécifications en aval telles que la pompe de fusion, changeur d'écran, et la boîte de vitesses de l'extrudeuse peut être adaptée au débit. Vous pouvez valider les options par rapport aux catalogues des fabricants tels que les listes d'extrudeuses à double vis Made-in-China.com ici et la catégorie matériel d'occasion Euro-Machinery ici, mais je les considère comme des points de départ, ne remplace pas l'adaptation préalable de la géométrie à votre matériau.

Spécifications des clés de décodage: Diamètre de vis, L/D, kW, RPM, et sortie

Quand j'ouvre une fiche fournisseur, Je l'ai lu comme une histoire sur la façon dont une machine se comportera avec mon matériel, pas comme une liste de chiffres à admirer. Les spécifications les plus importantes sont regroupées dans un groupe restreint: diamètre de vis, L/D ratio, puissance du moteur en kW, vitesse maximale de la vis en tr/min, et débit nominal en kg/h. Une fois que vous pouvez traduire ces cinq chiffres en réalité de traitement, le reste d'une négociation de vente en gros d'extrudeuse à double vis devient beaucoup plus ancré.

Diamètre de vis comme convention de dénomination du modèle

La plupart des catalogues de gros nomment leurs machines d'après le diamètre de la vis, c'est pourquoi vous voyez une gamme allant du TSE-20 au TSE-50. Le nombre est le diamètre de chaque vis en millimètres. Un TSE-20 transporte 20 vis mm; un TSE-50 transporte 50 vis mm. Le diamètre définit le plafond de débit et l'enveloppe de couple, c'est donc la première variable à laquelle je m'ancre. Les gammes de produits en gros construites autour de cette convention couvrent généralement une production d'environ 10 kg/h sur les plus petites unités de laboratoire jusqu'à environ 150 kg/h sur les modèles de production milieu de gamme (spécifications du produit twinscrewgranulator.com, 2024).

Une mise en garde par expérience: le diamètre à lui seul ne vous dit pas l'architecture. UN 50 La machine de mm peut être une conception à engrènement co-rotative pour la composition, une conception contrarotative pour les travaux sensibles au cisaillement, ou une extrudeuse conique bivis optimisée pour le PVC. Confirmez la configuration des vis ainsi que le diamètre avant de comparer deux machines partageant un numéro de modèle..

Rapport L/D et son effet sur le temps de séjour

Le rapport L/D est la longueur de traitement du canon divisée par le diamètre de la vis. Parmi les offres de gros que j'ai examinées, cela varie d'environ 24:1 à 80:1. Un fût plus long donne à la fonte plus de temps de séjour, plus d'espace pour les opérations séquentielles, et plus d'espace pour installer des mangeoires latérales, zones de dégazage sous vide, et des blocs de pétrissage supplémentaires. Un canon plus court refroidit les matériaux sensibles à la résidence, mais limite le nombre d'opérations unitaires que vous pouvez effectuer le long de la vis..

J'adapte L/D au travail plutôt que de courir après le canon le plus long. Extrusion réactive, composés fortement chargés, et la dévolatilisation veulent généralement un L/D généreux pour que je puisse séquencer l'alimentation, fusion, mélange, et ventilation sans encombrement. La granulation simple d'une seule résine nécessite rarement le fût le plus long disponible. La disposition des éléments de vis à l'intérieur de cette longueur, le placement des blocs de pétrissage et des éléments de transport, détermine en fin de compte si le L/D est bien utilisé ou gaspillé.

Puissance du moteur (kW) et vitesse maximale (RPM) Compromis

La puissance du moteur et la vitesse de la vis définissent ensemble la quantité d'énergie spécifique que vous pouvez mettre dans le matériau.. La vitesse maximale de la vis sur les extrudeuses à double vis de production se situe généralement entre 400 et 600 tr/min, tandis que les unités pharmaceutiques et expérimentales sont souvent spécifiées dans un 50 à 600 plage de régime pour un contrôle précis à l'échelle du laboratoire (Liste des usines d'extrudeuse à double vis de laboratoire en Chine, 2024). Pour un contexte à grande échelle, une unité de laboratoire en gros peut jumeler un 25 vis de mm avec un 7.5 Moteur kW et un 50 kg/h (Liste des extrudeuses à double vis de laboratoire de gros Accio, 2026), alors qu'un 100 kg/h machine semi-automatique d'un fabricant indien est construite autour d'un 80 kW entraînement (Nouvelles machines en plastique, Bahadurgarh, 2024).

Le compromis que je pèse est le couple par rapport à la vitesse. Un régime élevé augmente le débit mais ajoute du cisaillement et de la chaleur, ce qui est risqué pour les résines et biopolymères thermosensibles. Un arbre à couple élevé me permet de fonctionner à un régime inférieur tout en augmentant le débit, qui protège la fonte. Lorsqu'un fournisseur indique uniquement le régime maximal sans le couple nominal ni le chiffre d'énergie spécifique, Je demande les spécifications complètes du lecteur avant de faire confiance au résultat du titre.

Lecture des valeurs nominales de sortie (kg/heure) De façon réaliste

La production nominale est le nombre qui est survendu le plus souvent. Le chiffre kg/h sur une brochure reflète généralement un matériau idéal dans des conditions idéales, souvent une polyoléfine fluide. Mon débit réel dépend de la densité apparente, Fabricant d'extrudeuses à l'échelle de laboratoire chargement de remplissage, viscosité de fusion, humidité, et de combien de ventilation ou de refroidissement en aval j'ai besoin. Une machine évaluée à 150 kg/h sur PE peut fournir beaucoup moins sur un composé fortement chargé ou une qualité sensible au cisaillement.

En pratique je demande au fabricant un rendu sur mon matériel spécifique, ou au minimum sur l'analogue le plus proche qu'ils ont exécuté. Je confirme également si le chiffre nominal suppose une pompe à fonte, un changeur d'écran, et une tête de granulation en ligne, parce que ces composants en aval affectent un débit durable. Traiter le catalogue kg/h comme un point de départ plutôt que comme une garantie m'a évité plus d'une fois des achats sous-dimensionnés..

Faire correspondre les modèles d'extrudeuses à vos exigences de sortie

Une fois que les spécifications ont du sens, la décision d'achat se réduit à une simple question: combien de produit dois-je fabriquer par heure, aujourd'hui et dans les années à venir? Je trie le marché en trois niveaux, et faire correspondre mon volume au bon niveau évite à la fois l'erreur coûteuse de surachat et l'hémorragie plus lente de devenir trop grande pour une machine en un an..

Échelle de laboratoire et pilote (~10–50 kg/heure) pour R&D et petites séries

Pour le développement de formulations, petits lots personnalisés, et travaux de preuve de concept, une extrudeuse à double vis à l'échelle du laboratoire dans le 10 à 50 La bande kg/h est la bonne solution. Ces machines, généralement TSE-20 à TSE-25, maintenir une consommation de matériaux faible tout en étant évolutif, afin qu'une recette développée ici puisse être transférée en production. L'unité de laboratoire de gros que j'ai citée plus tôt, 25 vis mm, 7.5 Moteur kW, 50 sortie kg/h avec contrôle PLC et dégazage sous vide, est représentatif de ce que propose ce niveau (Liste des extrudeuses à double vis de laboratoire de gros Accio, 2026). Je recommande ce niveau à R&Groupes D, universités, et startups validant un produit avant d’engager du capital.

Milieu de gamme (~60–150 kg/heure) pour les startups de production

Quand une entreprise passe de la validation à la fourniture commerciale, le 60 à 150 La plage kg/h devient la bête de somme. C'est là que la plupart des files d'attente en gros concentrent leur volume, et il couvre l'essentiel de la fabrication du mélange maître, composition en petits lots, et opérations régionales de granulation. Le 100 kg/h, 80 Machine semi-automatique kW prix autour de Rs 15,00,000 se situe carrément dans cette bande et illustre le niveau de capital impliqué (Nouvelles machines en plastique, Bahadurgarh, 2024). Mon conseil aux startups de production est d'acheter au maximum de leur demande réaliste à court terme, parce que le coût supplémentaire du déménagement 80 à 150 kg/h est bien inférieur au coût de remplacement d’une machine devenue trop grande.

Lignes à haut rendement (200–4,000 kg/heure) pour l'échelle industrielle

Les formulateurs et recycleurs établis opèrent dans une ligue différente. Inventaires de machines d'occasion de marques telles que Berstorff, KraussMaffei, et Maris couvrent les sorties de 100 kg/h jusqu'à 4,000 kg/heure (Catégorie extrudeuses bivis Euro-Machinery, 2024). A cette échelle, une machine d'extrusion industrielle fait partie d'une ligne de production d'extrusion clé en main avec alimentation gravimétrique, plusieurs mangeoires latérales, pompes à fonte, changeurs d'écran automatiques, et pelletisation intégrée. Ce sont de grands projets d’investissement, et le marché secondaire est suffisamment profond pour être une option sérieuse, que je couvre dans les niveaux d'approvisionnement ci-dessous.

Exemple de tableau du modèle TSE

Le tableau ci-dessous consolide les niveaux dans une référence rapide. Je l'ai construit à partir de la convention de dénomination basée sur le diamètre et des chiffres de sortie et de puissance cités ci-dessus.; traiter la colonne de sortie comme une plage représentative pour une résine fluide, pas une garantie pour votre matériel.

Modèle	Diamètre de vis	Puissance typique du moteur	Sortie représentative	Application la mieux adaptée
20	20 mm	~4–7.5 kW	~10–25 kg/heure	Laboratoire R&D, formulation
EST-25	25 mm	~7,5 kW	~30–50 kg/heure	Échelle pilote, petites séries personnalisées
EST-35	35 mm	~30–45 kW	~60–120 kg/heure	Démarrage de la production, mélange maître
50	50 mm	~55–80 kW	~120–150+ kg/heure	Composition commerciale, granulation
Lignes industrielles	65 mm et plus	100+ kW	200–4,000 kg/heure	Recyclage et mélange à grande échelle

Guide de candidature: Recyclage, Composition, Tuyau, et la nourriture

Les spécifications et les niveaux de sortie n’ont de sens qu’au sein d’une application. Le même diamètre et le même L/D peuvent être configurés pour des travaux très différents, et l'architecture à vis, co-rotatif versus contrarotatif versus conique, est généralement dicté par le matériau et le produit final. Below I walk through the four application families I am asked about most when sourcing wholesale, and why the configuration matters for each. The versatility that lets one platform serve plastics, médicaments, nourriture, and chemicals is precisely why these machines hold their value across industries (Haut 20 Fabricants d'extrudeuses à double vis, 2025).

Plastic Recycling and Pelletizing (ANIMAL DE COMPAGNIE, RPET, PE, PP)

For recycling, a co-rotating intermeshing twin screw extruder paired with strong devolatilization is my default. Post-consumer PET and RPET carry moisture and volatiles, so vacuum degassing along a longer L/D barrel is essential for clean pellets and stable intrinsic viscosity. PE and PP recyclate need robust melt filtration, which is where an automatic screen changer and a melt pump earn their keep by keeping pellet quality consistent as contamination varies. Une extrudeuse de recyclage de plastique construite de cette manière fonctionne comme une machine de granulation de plastique complète lorsqu'elle est équipée d'une tête de granulation à filière ou à brins..

Masterbatch et Masterbatch de remplissage (CaCO3) Composition

Le mélange est la discipline pour laquelle les extrudeuses à double vis ont été construites. Mélange maître de couleur, mélange maître additif, et les mélanges maîtres de charges à forte charge tels que le carbonate de calcium reposent tous sur le mélange distributif et dispersif fourni par les blocs de pétrissage et une disposition bien séquencée des éléments à vis.. Pour le mélange maître de remplissage, J'ajoute un alimentateur latéral pour que le CaCO3 entre en aval du polymère fondu plutôt que d'affamer la gorge d'alimentation principale., qui protège le débit et la qualité de la dispersion. Une extrudeuse de mélange configurée avec les bonnes sections de pétrissage est ce qui sépare un mélange maître uniforme d'un mélange avec un développement de couleur médiocre ou des agglomérats..

PVC Pipe and Profile Extrusion Lines

PVC is the classic case for counter-rotating and conical geometries. A conical twin screw extruder, with screws that taper from a larger diameter at the feed to a smaller diameter at the die, suits the low shear and tight temperature control that heat-sensitive PVC demands. These machines anchor PVC pipe extrusion line and profile setups. For pelletizing soft and rigid PVC, conical counter-rotating twin screw extruders are used with downstream die-face cutting and cooling (Ligne de granulation conique à double vis en PVC JWELL Machinery, 2024). On the secondary market, used conical PVC pipe extruders are quoted around US $25,000 par ensemble, which makes this a tier where refurbished equipment is worth a serious look (Made-in-China.com a utilisé la vente en gros d'extrudeuse à double vis, 2024).

Nourriture, Pet Food, and Pharmaceutical Experimental Extruders

Outside plastics, twin screw extruders cook, texturize, and shape. A pet food extruder uses controlled shear and moisture to gelatinize starch and form kibble, while food lines produce snacks, céréales, and texturized proteins. Pharmaceutical experimental extruders, used for hot-melt extrusion and continuous granulation, prize precision over volume and commonly operate across a 50 à 600 plage de régime pour un contrôle précis à l'échelle du laboratoire (Liste des usines d'extrudeuse à double vis de laboratoire en Chine, 2024). For these regulated applications, I treat certifications as a gating requirement rather than a bonus: GMP and ISO9001 appear regularly in supplier taxonomies alongside CE and UL (Taxonomie des certifications Made-in-China.com, 2024), and I will not source food or pharma equipment without confirming the relevant marks. For deeper specification comparisons on lab-grade units, supplier catalogs such as the laboratorial twin screw extruder listings and broader Made-in-China twin-screw extruder catalogs are useful starting points before I shortlist suppliers.

Lab and Experimental Twin Screw Extruders for Wholesale

Before I commit a client's capital to a production line that runs 24 hours a day, I almost always recommend proving the formulation on a lab-scale unit first. A twin screw extruder is a process tool, not just a machine, and the cheapest way to discover that a recipe shears poorly, degasses badly, or pellets inconsistently is on a small footprint that costs a fraction of full production. D'après mon expérience, the money spent on a pilot run pays for itself the moment it prevents a six-figure mistake on the wrong screw configuration.

When a Lab-Scale Unit Makes Sense Before Bulk Commitment

I treat a lab unit as the right call in three situations: when the formulation is unproven, when I am qualifying a new supplier's build quality, and when downstream customers demand sample material before they sign volume contracts. A small co-rotating twin screw lets me validate residence time, température de fusion, and torque demand on real material rather than on a datasheet. If those numbers hold, scaling becomes an engineering exercise instead of a gamble.

Pharmaceutical and Pilot-Scale Features

Pilot machines are defined by control resolution rather than raw output. A representative wholesale lab listing specifies a 25 mm diamètre de vis, un 7.5 Moteur kW, and roughly 50 kg/h with PLC control and vacuum degassing (Liste des extrudeuses à double vis de laboratoire de gros Accio, 2026). For pharmaceutical hot-melt extrusion, the speed envelope matters more than throughput: experimental units commonly operate across a 50–600 rpm range to map shear sensitivity on small batches (Liste des usines d'extrudeuse à double vis de laboratoire en Chine, 2024). When I evaluate a pharma-grade unit, I look for GMP documentation, an intermeshing twin screw geometry that gives predictable mixing, and a PLC that logs the process curve I will later need for regulatory submission.

Sample and Test Units Offered by Suppliers

Many serious manufacturers keep a demonstration extruder in-house and will run your material on it. I always ask for this before placing a wholesale order. A supplier who will process your resin or active ingredient and return both the pellets and the recorded torque, température, and vacuum data is demonstrating capability; one who refuses is asking you to buy on faith. Request retained samples, the run sheet, and a video of the die face during the trial.

Scaling From Lab Geometry to Production Geometry

The point of pilot work is a clean scale-up, and the connective tissue is geometry. I keep the L/D ratio constant between lab and production where possible, preserve the kneading block sequence, and scale throughput against the cube of the screw diameter ratio as a first approximation rather than linearly. Side feeder position, screw element layout, and vacuum degassing port location should migrate to the larger machine in the same relative positions. When the lab unit uses a 25 mm screw and the production line uses a high-torque shaft on a 65 mm or 75 mm platform, I confirm with the manufacturer that the specific energy input (kWh/kg) is matched, because that, not output alone, governs product quality.

New vs Used vs Refurbished: A Wholesale Cost Comparison

Once the process is proven, the question becomes how to acquire capacity at the lowest sensible risk. I think of this as three distinct markets rather than one price ladder. New machines buy certainty and warranty; used machines buy speed and steep discounts; refurbished machines sit in between when a reputable shop has restored the wear surfaces. The right choice depends as much on your tolerance for downtime as on the sticker price.

Used-Machine Marketplaces and Brand Availability

The secondary market for this equipment is genuinely deep. Made-in-China.com alone lists over 74,746 Vente en gros de produits d'extrudeuse à double vis d'occasion, which tells me liquidity is rarely the constraint (Made-in-China.com a utilisé une extrudeuse à double vis, 2024). For premium European iron, dealers such as Euro-Machinery carry inventory spanning brands like Berstorff, KraussMaffei, et Maris, with outputs running from 100 kg/h jusqu'à 4,000 kg/heure (Catégorie extrudeuses bivis Euro-Machinery, 2024). When a buyer wants a known compounding extruder platform with documented service history, I steer them toward these branded listings rather than anonymous lots.

Price Bands and What They Buy

Pricing across the batch of sources I reviewed varies by more than two orders of magnitude, so the band you target should map to a specific machine class.

Acquisition path	Representative price	Typical class	Source
Used conical PVC line	~US $25,000 par ensemble	Counter-rotating conical twin screw, Extrusion de tuyaux en PVC	Made-in-China.com used listing (2024)
New mid-range (Inde)	~Rs 15,00,000 (≈NOUS $18,000) par pièce	100 kg/heure, 80 kW semi-automatic	Nouvelles machines en plastique, Bahadurgarh (2024)
Wholesale spread	Under US $2/unit at scale to over US $200,000/set	Components to full turnkey extrusion production lines	Accio wholesale listing (2026)

The roughly US $25,000 used conical PVC machine is a useful anchor (Fabriqué en Chine.com, 2024). Conical counter-rotating designs are purpose-built for soft and rigid PVC pelletizing with downstream die-face cutting and cooling (Ligne de granulation conique à double vis en PVC JWELL Machinery, 2024), so that price reflects a focused, single-purpose plastic pelletizing machine rather than a flexible compounder.

Risks of Used Equipment

The discount on used iron is real, but so are the liabilities. The first thing I inspect is the extruder screw and barrel, because clearance growth from abrasive or filled compounds destroys mixing performance long before the gearbox fails. I check for parts availability next: a machine from a discontinued line or a manufacturer that has exited the market can become unserviceable when a screw element or screen changer wears out. Warranty gaps are the third trap. Most used sales are as-is, which means a cracked extruder gearbox case or a failing melt pump becomes your problem on day one. I budget for an independent inspection and a spare-parts survey before I let a client wire funds.

When Refurbished Delivers the Best ROI

Refurbished is where I see the strongest return when two conditions hold: a reputable shop has replaced the wear surfaces, and the underlying platform is from a brand with current parts support. A properly rebuilt machine with new screw elements, a re-lined barrel, and a serviced gearbox can deliver 80 à 90 percent of new-machine reliability at well under half the cost, and it ships faster than a new build's lead time. I ask for the refurbishment scope in writing, the replaced-parts list, and at least a limited warranty on the rebuilt components. Without that documentation, a "refurbished" label is just a used machine with a fresh coat of paint.

OEM, ODM, and Own-Brand Sourcing Options

The final sourcing decision is about whose name and whose engineering goes on the machine. I find that buyers conflate OEM, ODM, and own-brand manufacturing, and the confusion costs them leverage in negotiation. Getting the terminology right lets you ask the supplier for exactly the relationship you want.

Definitions That Change the Negotiation

OEM, in the way most twin screw extruder manufacturer relationships use it, means the factory builds to your specification and you apply your branding. ODM means the factory contributes the design, often from an existing platform, and you commission units from it. La fabrication sous marque propre signifie que vous contrôlez le design, la marque, et souvent la propriété intellectuelle, l'usine agissant uniquement en tant que constructeur sous contrat. Les annuaires de fournisseurs codent déjà cela: Les filtres Made-in-China.com distinguent le fabricant/usine, société commerciale, et types d'entreprises de sociétés de groupe, et signalez la capacité OEM/ODM directement dans la recherche (Filtres de recherche pour extrudeuse à double vis Made-in-China.com, 2024).

Quand l’étiquetage privé ou le branding personnalisé s’avèrent payants

L'étiquetage privé gagne sa prime lorsque vous revendez des machines ou construisez une ligne sous votre propre nom pour la revente et le service.. Si vous êtes un utilisateur final exécutant l'extrudeuse dans votre propre usine, la marque ajoute peu et je ne paierais pas pour cela. Le retournement économique pour les distributeurs et les intégrateurs de systèmes, où une ligne d'extrudeuse à double vis de marque propre soutient la marge, contrôle de garantie, et un catalogue produits cohérent. I make the call on whether the machine is a cost center or a product.

Customization of Screw Geometry, Feeders, and Controls

This is where OEM and ODM arrangements create real value. The customizations I request most often are screw element and kneading block sequences tuned to the compound, a side feeder for fillers or fiber that should not pass the main throat, vacuum degassing ports placed for the volatiles in the formulation, and a melt pump plus screen changer for pressure stability and contamination control on a masterbatch making extrusion line. On the controls side, I specify the PLC, the data-logging depth, and the motor power in kW against the worst-case torque, then confirm the high-torque shaft rating supports it. A good factory will engineer these; a trading company will simply forward the request.

Choosing Between Trading Companies and Direct Factories

I default to direct factories for any customized or high-value order, because the engineering conversation has to happen with the people who cut the metal. Trading companies earn their place when I am consolidating several machine types, when I lack the language or logistics capacity to manage a factory directly, or when the factory's minimum order quantity is too high for my volume. The trade-off is margin and information distance: every layer between you and the welder dilutes both. Whichever path I take, I verify certifications directly, since the common taxonomy for this equipment includes CE, ISO9001, BPF, et UL (Taxonomie des certifications Made-in-China.com, 2024), and a certificate that the trading company cannot trace to a specific audit is a certificate I do not trust. For buyers comparing live inventory, established channels such as a Twin-screw extruder wholesale directory and dealer listings of used twin screw extruders are useful starting points for benchmarking specifications and screw extruder price before you commit.

Understanding Wholesale Pricing and Price Ranges

The first thing that surprises buyers new to twin screw extruder wholesale is the sheer width of the price band. D'après mon expérience, when a procurement lead asks "what does a twin screw extruder cost?" the honest answer is another question: what are you actually buying? Wholesale unit prices range from under US $2 par unité à l'échelle des composants extrêmes jusqu'à plus des États-Unis $200,000 par set pour une ligne industrielle entièrement configurée, selon une liste d'extrudeuses à double vis de laboratoire de plastique en gros Accio (2026, accio.com). Pour la plupart des lecteurs qui recherchent une machine complète plutôt que des pièces détachées, l'écart réaliste s'étend à peu près des États-Unis $1,950 pour une unité compacte à l'échelle d'un laboratoire aux États-Unis $200,000 et au-delà pour une extrudeuse de mélange à haut rendement avec automatisation en aval.

Où votre application atterrit sur la courbe des prix

Je trouve plus utile d'ancrer les attentes par application plutôt que par un seul numéro de titre.. Une extrudeuse double vis à l'échelle du laboratoire avec une vis de 25 mm, 7.5Moteur kW, 50 kg/h de rendement, Contrôle par API, et le dégazage sous vide se situe à l’extrémité abordable du marché de gros (Action, 2026). Passez à une machine de production semi-automatique et le chiffre grimpe vite: une fabrication indienne 100 kg/h, 80kW semi-automatic unit is priced around Rs 15,00,000 par pièce, which works out to roughly US $18,000 à 2024 exchange rates, per New Plast Machinery, Bahadurgarh (2024, indiamart.com).

Pet food and aquafeed buyers occupy their own bracket. A complete pet food twin screw line typically runs US $25,000 to US $80,000 par ensemble, reflecting the cooking-extrusion configuration, preconditioner, and downstream drying that distinguish a feed extruder from a plastics compounding extruder. The secondary market adds another option: used conical twin screw PVC pipe extruders are quoted around US $25,000 par ensemble, according to Made-in-China.com used twin screw extruder wholesale (2024, made-in-china.com).

Configuration / Application	Sortie typique (kg/heure)	Indicative Wholesale Price (USD/set)	Source
Laboratoire / experimental (25mm, 7.5kW, API)	~50	NOUS $1,950 – $8,000	Action (2026)
Semi-automatic production (80kW)	~100	~US $18,000	Nouvelles machines en plastique (2024)
Pet food / aquafeed twin screw line	100 – 1,000+	NOUS $25,000 – $80,000	Industry pet-food line range
Used conical PVC pipe extruder	variable	~US $25,000	Fabriqué en Chine.com (2024)
High-output industrial compounding line	jusqu'à 4,000	NOUS $80,000 – $200,000+	Action (2026); Euro-Machines (2024)

Figures are indicative wholesale ranges compiled from the cited listings; actual quotes vary with specification and supplier.

The Four Variables That Move Price

When I break down a quotation for a client, nearly every dollar of variation traces back to four levers. Screw diameter and output capacity come first: wholesale model lineups commonly use screw diameter as the naming convention, with output spanning roughly 10 kg/h à 150 kg/h on a single product family, per twinscrewgranulator.com product specifications (2024, twinscrewgranulator.com). Larger screws, longer L/D ratios, and high-torque shafts cost materially more.

Automation is the second lever. A PLC-controlled machine with closed-loop temperature zones, a melt pump, and an automatic screen changer commands a premium over a manual unit. Third is brand and provenance. Used-machine inventory spans premium European names like Berstorff, KraussMaffei, and Maris with outputs from 100 kg/h à 4,000 kg/heure, per Euro-Machinery's twin screw extruders category (2024, euro-machinery.com); those names carry resale value that no-name factory units do not.

Fourth is accessories and configuration. A bare extruder is one number; a turnkey extrusion production line with side feeder, dégazage sous vide, pompe à fonte, changeur d'écran, découpe à l'emporte-pièce, and cooling is another entirely. The conical counter-rotating twin screw extruders used for soft and rigid PVC pelletizing, par exemple, depend on downstream die-face cutting and cooling to function as a complete system, as JWELL Machinery describes for its PVC conical twin-screw pelletizing line (2024).

Spotting Prices That Are Too Good to Be True

A quote that undercuts the market by half should trigger questions, not a purchase order. The patterns I watch for: a "complete line" price that quietly excludes the gearbox, moteur, or control cabinet; a co-rotating compounding extruder priced like a single-screw machine; specifications that list an output figure without a corresponding motor power (kW) or screw diameter; and "new" units whose photographs show wear. The deep secondary market—Made-in-China.com répertorie plus de 74,746 Vente en gros de produits d'extrudeuse à double vis d'occasion (2024)—means some sellers relabel refurbished equipment as new. If the kneading block configuration, screw element layout, and L/D ratio are not specified, I treat the price as incomplete rather than competitive.

MOQ, Délais, and Sample Availability

One of the genuine advantages of capital-equipment wholesale, compared with consumable goods, is that minimum order quantities are forgiving. For machinery, MOQ is frequently as low as 1 set among wholesale suppliers—the Accio lab twin screw extruder listing is sold per single set (2026), and most factory and trading-company listings on the major B2B platforms quote per unit. That matters because it means a buyer can pilot a single machine before committing to a fleet.

Understanding Production Lead Times

Lead time is where I see procurement plans slip most often. A standard catalog model with a common screw diameter may ship from stock or within two to four weeks. A customized twin screw extruder—non-standard L/D ratio, specific kneading block geometry, a particular high-torque shaft rating, or an integrated turnkey line—commonly runs eight to sixteen weeks. The variables that stretch the timeline are configuration complexity, whether the gearbox and motor are in stock, queue position in the factory, and any third-party components (a branded melt pump or screen changer) that the manufacturer must source externally.

Business type affects lead time too. Made-in-China.com's supplier filters distinguish manufacturer/factory, société commerciale, and group corporation business types with OEM/ODM capacity (2024, made-in-china.com). D'après mon expérience, buying direct from a manufacturer/factory gives you the most accurate production schedule, while a trading company adds a coordination layer that can either smooth or lengthen the process depending on its relationship with the actual plant.

Requesting Samples and Test Units

You cannot order a "sample" extruder the way you would a sample of resin, but you can and should request proof before a bulk commitment. The two requests I make every time: a recorded factory acceptance test (GRAISSE) running the machine on your target material at your target output, et, for compounding or feed applications, a trial run that returns physical pelletized samples for your lab to validate. Pharmaceutical and lab buyers have a further check available—experimental extruders operate across a 50–600 rpm range for lab-scale processing per a China laboratory twin screw extruder factory listing (2024), so confirm the supplier can demonstrate stable output across that range before scaling.

Planning Procurement Timelines Around Delivery

I work backward from the date the line must be running. To a typical eight-to-sixteen-week production window, add ocean freight (commonly four to six weeks from Asia to the US West Coast, longer to inland destinations), plus customs clearance and inland delivery, plus installation and commissioning. A realistic door-to-production timeline for a custom industrial machine is four to six months. Catalog lab units compress that to weeks. Building this calendar before you sign protects you from the classic trap of a "12-week" machine that does not actually produce salable output until the following quarter.

Calculating Total Landed Cost, Not Just Unit Price

The single most expensive mistake I see in twin screw extruder wholesale is treating the ex-works quote as the budget. The unit price is the starting line, not the finish line. Total landed cost folds in freight, assurance, devoirs, electrical adaptation, and the labor to get the machine producing. On a heavy capital good, these additions routinely add 15 à 35 percent to the headline number.

Fret, Assurance, and Incoterms

Les extrudeuses à double vis sont lourdes, often crated as oversized or multi-piece shipments, so the Incoterm you agree to determines who carries which costs and risks. The three I negotiate most often:

• GOUSSET (Free On Board): the supplier delivers the machine onto the vessel at the origin port; you own the ocean freight, assurance maritime, and everything downstream. This gives you control over the forwarder and is my default for buyers with import experience.
• CIF (Coût, Insurance and Freight): the supplier arranges and pays ocean freight and minimum insurance to your destination port; you handle customs and inland delivery. Simpler for first-time importers, but you inherit whatever insurance coverage the seller minimally bought.
• DAP (Delivered At Place): the supplier delivers to your named address, bearing transport risk to that point, while you remain responsible for import duties and taxes. Pratique, usually the highest quoted Incoterm.

Always insure a capital machine for its full replacement value. The premium is small against the cost of a gearbox or barrel damaged in transit.

Import Duties, Taxes, and US Customs Clearance

For US importers, the machine clears under a Harmonized Tariff Schedule (HTS) classification—extrusion machinery generally falls within Chapter 84. The applicable duty rate, any Section 301 droits de douane sur les produits d'origine chinoise, and Merchandise Processing Fees all attach at entry. I strongly advise confirming the HTS code and current rate with a licensed customs broker before you commit, because a misclassification can swing the duty bill by thousands of dollars. The broker's fee, caution douanière, et tous les frais de manutention portuaire appartiennent également au modèle des coûts au débarquement.

Conversion de tension et compatibilité électrique

Cet élément de campagne est celui que les acheteurs oublient le plus.. Les machines construites pour les marchés asiatiques ou européens sont fréquemment câblées pour une alimentation triphasée de 380 V/50 Hz., alors que l'approvisionnement industriel américain est généralement de 480 V/60 Hz (ou 208/240 V dans les petites installations). Réconcilier cet écart peut nécessiter un transformateur élévateur/abaisseur, une considération de fréquence pour les valeurs nominales du moteur et du variateur, et recâblage de la commande Fournisseur de fabrication de plastique par extrusion armoire conforme au code électrique américain. Pour une machine dessinant 80 kW ou plus, le transformateur et les travaux électriques peuvent à eux seuls coûter plusieurs milliers de dollars. Je demande toujours par écrit au fournisseur quelle tension, fréquence, et mettre en phase les navires de machines configurés pour, and whether they can build it to US specification at the factory—which is almost always cheaper than retrofitting on arrival.

Installation, Mise en service, and Training

The final cost block is turning a delivered crate into a producing asset. Budget for rigging and placement, foundation or anchoring if required, utility connections (pouvoir, refroidissement par eau, compressed air), and the supplier's commissioning engineer. Many manufacturers offer on-site commissioning and operator training, but travel, lodging, and per-diem for their technician are usually your charge. For a turnkey extrusion production line, I treat commissioning and training as a non-negotiable line item, because an improperly tuned screw and barrel temperature profile or a miscalibrated melt pump will cost far more in scrap and downtime than the technician's visit.

Landed Cost Component	Part typique du prix unitaire	Remarques
Fret maritime + assurance maritime	5% – 12%	Plus élevé pour les envois surdimensionnés ou à destination de l'intérieur du pays
Droits d'importation + tarifs + frais	2% – 15%+	Confirmez le code HTS et la section 301 statut chez un courtier
Courtage en douane + lier	1% – 3%	Coûts par entrée et caution
Conversion de tension / électrique	2% – 8%	Évitez en commandant selon les spécifications américaines à l'usine
Installation, mise en service, entraînement	3% – 10%	Comprend les déplacements des techniciens et les indemnités journalières

Les parts sont des estimations de planification à des fins budgétaires et varient en fonction de la taille de la machine., origine, et destination; vérifiez chaque chiffre pour votre envoi spécifique.

Quand j'ajoute ces blocs au prix départ usine, la différence entre un budget naïf et un véritable coût au débarquement est flagrante. Une machine cotée chez US $40,000 peut raisonnablement atterrir aux États-Unis $48,000 to US $54,000 en fonctionnement. Construisez une image complète avant de négocier, et le prix de gros devient un outil de comparaison plutôt qu'une source de surprise.

Certifications et conformité à vérifier

Before I release a single dollar to any twin screw extruder manufacturer, I work through a certification checklist. Compliance documents are the cheapest insurance you can buy in this market, and the absence of them is the loudest red flag I know. On large sourcing platforms, the most common credentials attached to twin-screw equipment are CE, OIN 9001 (including the older ISO9001:2008 revision), BPF, et UL — that taxonomy comes straight from the certification filters on Made-in-China.com (2024) [https://www.made-in-china.com/products-search/hot-china-products/Twin-screw_Extruder.html]. Each one answers a different question, and I treat them as separate gates rather than a single badge. Plastic Recycling Extruder Machine Manufacturer

CE Marking for Safety Conformity

If the machine is bound for the European Economic Area, CE marking is non-negotiable. It declares that the equipment meets EU health, sécurité, and environmental requirements under the Machinery Directive. D'après mon expérience, a credible CE claim comes with a Declaration of Conformity and a technical file the supplier can produce on request. When a vendor lists "CE" but cannot send the declaration, I assume the mark is decorative. For an industrial extrusion machine with a high-torque shaft and a heated barrel, the safety scope covers guarding, arrêts d'urgence, and thermal protection — things you genuinely want validated.

OIN 9001 Gestion de la qualité

OIN 9001 certifies the manufacturer's quality management system, not the individual machine. That distinction matters. A factory holding a current ISO 9001 certificate has documented processes for traceability, corrective action, and supplier control, which is exactly what I want behind a compounding extruder I plan to run for a decade. I always check the certificate number against the issuing body's registry and confirm it has not lapsed, because an expired certificate tells me the quality discipline may have slipped.

GMP for Pharmaceutical Applications

When the extruder feeds a regulated process, GMP compliance moves to the top of the list. Pharmaceutical hot-melt extrusion demands contact surfaces, documentation, and validation protocols that a standard plastics line does not. Lab-scale pharmaceutical units typically operate across a 50–600 plage de régime pour le traitement expérimental, per a China laboratory twin screw extruder factory listing (2024) [https://www.example-lab-extruder.com/products], and that flexibility is only useful if the build itself meets GMP material and cleanability standards. I ask specifically whether the wetted parts are documented and whether the supplier has supplied GMP-grade equipment before.

UL and Electrical Compliance for the US Market

For a US installation, I verify UL listing or recognition on electrical components and the control panel. This is where total landed cost quietly inflates: many imported machines ship with 380 V three-phase wiring and IEC components that a local inspector will not pass without rework. Confirming UL compliance and the correct voltage before the deposit saves a costly retrofit after the crate lands.

Certification Quick Reference

Attestation	What it covers	Required when	How I verify it
CE	EU safety, health, environmental conformity	Selling/operating in the EEA	Declaration of Conformity + technical file
OIN 9001	Manufacturer's quality management system	Always preferred	Certificate number checked against issuing registry
BPF	Pharmaceutical-grade build and process control	Pharma or food-contact use	Material docs + prior GMP supply record
UL	US electrical safety on components/panel	US installation	UL file number + voltage spec confirmation

How to Vet a Twin Screw Extruder Manufacturer

Certificates tell me whether a machine can be compliant. Vetting tells me whether the company behind it will still answer the phone when I need a screw element three years from now. This is the step competitors skip — catalogs list specifications but rarely translate them into a structured way to judge the seller. Here is the process I run before shortlisting any Twin Screw Extruder Wholesale supplier.

Manufacturer vs Trading Company

The first filter I apply is business type. Sourcing platforms explicitly distinguish manufacturer/factory, société commerciale, and group corporation, and they flag OEM/ODM capacity separately — that classification is built into the Made-in-China.com search filters (2024) [https://www.made-in-china.com/products-search/hot-china-products/Twin-screw_Extruder.html]. I prefer dealing with the manufacturer directly because it shortens the after-sales chain and gives me access to the engineers who actually built the gearbox and the intermeshing screws. A trading company can still be useful for consolidating a turnkey extrusion production line from multiple makers, but I want to know which model I am dealing with so I can price the margin and the support gap accordingly.

Response Rate, Tenure, and Ratings

I treat a supplier's responsiveness during the inquiry stage as a preview of their after-sales behavior. Slow, vague answers before I have paid rarely improve afterward. Three signals carry the most weight for me:

• Response rate and speed — a manufacturer that answers technical questions within a business day.
• Years in business — longevity through market cycles suggests real engineering depth rather than a rebadged catalog.
• Platform ratings and transaction history — consistent volume on a double screw extruder line tells me the design is proven in the field.

References and Customer Reviews

I always ask for references in my own industry. A supplier strong in a PVC pipe extrusion line may have little experience with a pet food extruder or masterbatch making extrusion, and the screw geometry and L/D ratio differ across those jobs. Speaking to an existing customer about uptime, parts availability, and how the manufacturer handled a real failure has saved me from more bad decisions than any spec sheet. The breadth of the market means alternatives exist if references come back weak — Made-in-China.com alone lists over 74,746 Vente en gros de produits d'extrudeuse à double vis d'occasion (2024) [https://m.made-in-china.com/wholesale/used-twin-screw-extruder_2.html], so I am never forced to settle.

Factory Capacity and R&D Capability

Enfin, I assess whether the factory can actually build and support what it sells. Twin screw extruders span an enormous performance range — used-machine inventories alone run from roughly 100 kg/h à 4,000 kg/h across brands like Berstorff, KraussMaffei, et Maris, per Euro-Machinery (2024) [https://www.euro-machinery.com/product-category/plastic-recycling-machines/twin-screw-extruders/]. A manufacturer that genuinely engineers across that range will have in-house R&D for screw element and kneading block design, the ability to spec a side feeder, pompe à fonte, changeur d'écran, and vacuum degassing as a system, and the machining capacity to produce a high-torque shaft to tolerance. When I want a custom co-rotating configuration, R.&D depth is the difference between a tailored solution and a catalog substitution.

Quality Control and Pre-Shipment Inspection

Vetting reduces the odds of a bad partner; pre-shipment QC verifies the actual machine before it ever crates. This is the stage that protects your payment, and it is where I am most disciplined. Equipment values here range from lab units around US $25,000 for a used conical PVC line — quoted on Made-in-China.com (2024) [https://m.made-in-china.com/wholesale/used-twin-screw-extruder_2.html] — up to large compounding systems exceeding US $200,000 par ensemble, as seen in Accio's wholesale listings (2026) [https://www.accio.com/plp/wholesale-plastic-lab-twin-crew-extruder-1-set]. At those values, inspection is not optional overhead.

Third-Party Inspection and Factory Audits

For any significant order, I commission a third-party inspection rather than relying on the supplier's own photos. An independent inspector visiting the factory verifies that the machine being built matches the contract specification — correct screw diameter, puissance du moteur en kW, and L/D ratio — and that the workmanship meets standard. When the relationship is new or the order is large, I add a full factory audit covering machining equipment, welding quality, and the QC process itself. The audit confirms the capacity claims I evaluated during vetting are real.

Trial Runs and Performance Acceptance Criteria

I never accept a machine on appearance alone. I require a witnessed trial run, in person or by live video, against written acceptance criteria. Output is the headline number, and wholesale model lineups typically name their machines by screw diameter with outputs from roughly 10 kg/h à 150 kg/heure, per twinscrewgranulator.com specifications (2024) [https://www.twinscrewgranulator.com/buy-twin-screw-extruder.html]. My acceptance sheet captures more than throughput: stable melt temperature, motor amperage under load, torque stability on the high-torque shaft, vacuum degassing performance, and consistent pellet geometry from the die-face cutter. A lab unit I once specced — un 25 mm, 7.5 kW, 50 kg/h configuration with PLC control and vacuum degassing, the kind Accio lists (2026) [https://www.accio.com/plp/wholesale-plastic-lab-twin-crew-extruder-1-set] — only earned sign-off after it held output and melt temperature across a sustained run, not a thirty-second demo.

Inspecting Screws, Barils, and Gearbox Quality

The components that determine an extruder's working life are the ones buyers inspect least carefully. I focus on three:

• Extruder screw and barrel — I check for the specified wear-resistant alloy or nitriding, état de surface, and clearance tolerance, because the screw and barrel are the first parts to wear and the most expensive to replace. Aftermarket screw and barrel parts are a whole supply category of their own [https://www.twinscrewextruder-parts.com/products.html].
• Boîte de vitesse — the extruder gearbox transmits torque to the shafts; I confirm the rated torque margin, bearing brand, and that it runs without abnormal noise or temperature rise during the trial.
• Screw elements and kneading blocks — for a compounding extruder, I verify the element sequence matches the agreed process design, since this controls mixing quality.

Documenting QC Before Payment Release

Every inspection feeds a record, and I tie that record directly to payment milestones. My standard structure withholds the final balance until a signed inspection report, the trial-run data sheet, and the certification documents are all in hand. This is the gap most wholesale guides leave open: linking QC sign-off to the payment schedule turns inspection from a formality into leverage. I keep the documentation package — inspection report, acceptance criteria results, certificate copies, and component verification — as the basis for any warranty claim later. If a dispute arises, that paper trail is what protects me, and assembling it before the final transfer is the single most reliable QC habit I have.

For buyers comparing options across new, utilisé, and OEM/ODM routes, established marketplaces such as the Made-in-China twin-screw category (supplier listings and certification filters) and Euro-Machinery's used inventory (branded second-hand extruders) are useful starting points for benchmarking specifications and credentials before you commit to inspection.

Payment Terms and Incoterms for International Orders

Once I have shortlisted a supplier and locked the technical specification, the conversation shifts to money and risk. D'après mon expérience, this is where wholesale extruder deals either become predictable or quietly turn into disputes. A clear payment structure and a correctly chosen Incoterm protect my deposit, define who pays for what, et supprimez la plupart des ambiguïtés qui apparaissent au moment où une machine quitte l'usine..

Conditions de paiement courantes dans le commerce de gros des extrudeuses

La plupart des usines avec lesquelles je travaille citent l'un des quelques modèles familiers. L'arrangement dominant est T/T (transfert télégraphique) réparti sur plusieurs jalons: un dépôt pour commencer la production, puis le solde contre preuve de préparation ou d'expédition. UN 30/70 split est la ligne de base que je vois le plus souvent, bien qu'il soit parfois demandé aux primo-accédants provenant de fournisseurs inconnus 50% à l'avant.

• Dépôt T/T plus solde avant expédition: La norme pour les extrudeuses de mélange et les lignes clé en main. Je considère le dépôt comme un déclencheur de production et le solde comme le levier qui permet au fournisseur de rendre des comptes jusqu'au contrôle final..
• Lettre de crédit (L/C): Pour les commandes de valeur supérieure, especially when a single set runs into six figures, an irrevocable L/C shifts the risk to the banks. It costs more in fees and paperwork, but for a US $200,000+ set it is money well spent.
• Balance against documents: I release the final payment only after I receive (or my agent confirms) shipping documents and a passed inspection report, not on the supplier's verbal assurance.

Protecting deposits with milestone payments

A flat 30/70 split is fine for a trusted partner, but for a new factory I prefer to break the schedule into smaller, evidence-backed stages. Tying money to verifiable progress is the single most effective way I have found to keep a deposit from disappearing into a stalled order.

• 20–30% dépôt to start fabrication of the extruder screw and barrel.
• 30–40% milestone on completion of the gearbox assembly and motor mounting, ideally confirmed with timestamped photos or a short video.
• Final 30–40% after a successful factory acceptance test (GRAISSE) and pre-shipment inspection.

Wholesale unit prices range from under US $2 per unit at scale to over US $200,000 par ensemble (Liste des extrudeuses à double vis de laboratoire en plastique Accio en gros, 2026, accio.com). That enormous spread is exactly why I size the milestone structure to the order value: a sub-thousand-dollar lab unit does not justify L/C overhead, but a 4,000 kg/h compounding line absolutely does.

Using escrow and trade assurance where available

When I source through a B2B marketplace, I lean on the platform's built-in protection rather than wiring funds directly. Escrow and trade-assurance programs hold my payment until I confirm the order meets the agreed terms, which gives me a neutral arbiter if quality or delivery falls short. I only step outside that protection once a supplier has earned it across several orders, and even then I keep the milestone discipline intact.

Incoterms: knowing exactly where my responsibility begins

Incoterms 2020 define the precise point at which cost and risk transfer from seller to buyer. Choosing the wrong term is how a "cheap" machine becomes expensive at the port. The three I encounter most in extruder sourcing are below.

Incoterm	Seller's responsibility	Buyer's responsibility	When I use it
EXW (Ex Works)	Make the machine available at the factory gate only	All export clearance, inland freight, fret maritime, assurance, devoirs, import clearance, livraison	Rarement, and only when I have a strong local agent in the supplier's country
GOUSSET (Free On Board)	Deliver goods cleared for export and loaded onto the vessel at the named port	Fret maritime, assurance, droits d'importation, destination handling, final delivery	My default for containerized extruder shipments; clean risk handoff at the loading port
CIF (Coût, Assurance, Fret)	Freight and minimum insurance to the destination port	Import clearance, devoirs, destination handling, inland delivery	When I want the supplier to manage ocean logistics and I lack a freight forwarder

My practical rule: under FOB I gain control of routing and insurance levels, which usually lowers my total landed cost, but I must arrange a forwarder. Under CIF the supplier handles the sea leg, which is convenient but means I inherit whatever (often minimal) insurance they purchase. Whichever term I choose, I confirm in writing who clears export at origin and who handles the import duties at destination, because those two line items are where buyers most often get surprised.

Des pièces de rechange, Wear Components, and Accessories

A twin screw extruder is a modular machine, and that modularity is its greatest operational advantage. The wear parts are designed to be replaced, which means uptime over the next decade depends as much on parts strategy as it does on the initial purchase. When I negotiate a wholesale order, I treat the spare parts package as part of the deal, not an afterthought I scramble for once the warranty expires.

Éléments à vis, blocs à pétrir, and conveying elements

On a co-rotating intermeshing twin screw, the screws themselves are assemblies of individual segments keyed onto a shaft. This segmented design lets me tune the process and replace only the worn portions rather than scrapping an entire screw.

• Eléments de convoyage transport material forward; their flight depth and pitch set throughput.
• Blocs à pétrir deliver the dispersive and distributive mixing that makes the twin screw the workhorse of compounding. They are also among the first components to show wear because of the shear they generate.
• Éléments à vis in general are consumables on abrasive feedstocks. Glass-filled compounds and recycled streams with contamination chew through standard nitrided steel far faster than virgin resin, so I match the element metallurgy to the material I actually run.

Barils, high-torque shafts, and side feeders

The barrel forms the bore the screws rotate in, and like the elements it wears from the inside out. Bimetallic liners extend barrel life considerably on aggressive applications, and I always ask whether replacement barrel sections are stocked or made to order, because a custom-machined barrel can mean weeks of downtime.

The high-torque shaft transmits power from the gearbox into the screw assembly. Modern high-torque designs let a smaller-diameter machine push more output, but they concentrate stress, so I want spline and coupling spares on hand. The side feeder is the accessory that turns a general-purpose extruder into a true compounding extruder, metering fillers, fibres, or additives downstream of the main feed. If my formulation depends on high filler loading, the side feeder and its own small screw set become critical wear items in their own right.

Melt pumps, changeurs d'écran, and vacuum degassing

Downstream of the process section, three components govern output quality and consistency:

• Melt pump: A gear pump that stabilizes pressure and smooths output surge, essential when I need tight dimensional tolerance on a pelletizing or sheet line.
• Screen changer: Filters contamination from the melt. On a plastic recycling extruder this part earns its keep daily; a continuous or backflush screen changer avoids the line stops that a manual one forces.
• Vacuum degassing: Pulls moisture and volatiles out of the melt through vent ports. Lab and experimental units commonly bundle this in — Par exemple, un 25 mm, 7.5 kW, 50 kg/h wholesale lab unit ships with PLC control and vacuum degassing (Liste des extrudeuses à double vis de laboratoire de gros Accio, 2026, accio.com). I keep spare seals and check the vacuum pump as part of routine maintenance.

Stocking critical wear parts to avoid downtime

The economics here are straightforward: a few thousand dollars of shelf inventory protects against tens of thousands in lost production. My standing recommendation is to stock the items that both wear predictably and carry long lead times. A dedicated parts supply chain exists precisely because these components are consumable (see, Par exemple, the screw and barrel parts catalog at twinscrewextruder-parts.com).

• A full set of kneading blocks and the most-worn conveying elements.
• Barrel liner sections for the highest-shear zones, if the design allows liner replacement.
• Melt pump and gearbox seals, screen-changer screens, and vacuum vent gaskets.
• Shaft couplings and any proprietary fasteners.

I also confirm the part numbering and metallurgy at the time of purchase, because a wholesale machine assembled from generic parts can be impossible to re-source years later if the original drawings are not on file.

Efficacité énergétique, Sortir, and Operating Cost Analysis

Le prix d'achat est le plus petit chiffre du coût de vie d'une extrudeuse. Over a machine's working life, électricité, refroidissement, travail, et l'usure éclipse généralement la mise de fonds. Donc avant de m'engager dans une commande en gros, Je modélise le coût de fonctionnement, car une machine un peu plus chère mais plus efficace l'emporte presque toujours sur un horizon de plusieurs années.

Consommation d'énergie par rapport au débit (kW contre kg/h)

La métrique qui m'intéresse est la consommation d'énergie spécifique — puissance du moteur installée par rapport à la puissance nominale. Un contrôle de cohérence utile provient des spécifications de gros publiées: une fabrication indienne 100 L'extrudeuse à double vis semi-automatique kg/h est évaluée à 80 kW (Nouvelles machines en plastique, 2024, indiamart.com), tandis qu'une unité de laboratoire associe un 7.5 Moteur kW avec 50 kg/h de rendement (Action, 2026). Comparing the ratio rather than the headline numbers is what tells me whether a machine is efficient for its job.

Machine class	Sortir (kg/heure)	Installed power (kW)	Environ. kW per 100 kg/heure	Source
Laboratoire / experimental	50	7.5	~15 kW	Action (2026)
Production semi-automatic	100	80	~80 kW	Nouvelles machines en plastique (2024)

The contrast looks dramatic, and it illustrates an important point: lab units are not loaded the way a production line is, and rated power is not the same as actual draw under full process load. I read installed kW as the ceiling, then ask the supplier for measured consumption at my target throughput and material. A motor rarely runs at its nameplate; the real figure depends on screw configuration, fill level, and melt viscosity.

Systèmes de refroidissement: water vs air cooling cost impact

Barrel cooling is a recurring cost that buyers routinely underestimate. The two common approaches carry different cost profiles:

• Refroidissement par eau handles high heat loads efficiently and is standard on compounding and high-output lines. The tradeoff is the supporting infrastructure: a chiller, pumps, tuyauterie, and water treatment, all of which add to both capital and running cost.
• Refroidissement par air is simpler and cheaper to install, with lower maintenance, but it struggles to remove heat fast enough on high-throughput or high-shear processes.

For a lab-scale twin screw extruder or a modest pelletizing duty, air cooling often suffices. For a continuous PVC pipe extrusion line or a recycling operation running multiple shifts, I budget for water cooling and fold the chiller's energy draw into the total operating model, not just the extruder motor.

Automation grade and labor cost reduction

Automation grade is where operating cost meets headcount. The wholesale market spans a clear ladder from semi-automatic units (le 100 kg/h machine above is explicitly semi-automatic) up to fully automated, PLC-controlled lines with vacuum degassing and recipe management. A PLC-driven line holds process parameters tighter, réduit les déchets, and lets one operator supervise more equipment. In regions with higher labor rates, the payback on automation can be rapid; where labor is inexpensive, a semi-automatic machine may be the rational choice. I size automation to my own labor economics rather than buying the most automated option by reflex.

Estimating cost per kilogram of processed material

The figure that makes machines genuinely comparable is cost per kilogram of finished product. I build it from four inputs:

• Énergie: measured kW under load × local electricity rate ÷ kg/h de rendement.
• Travail: operator cost per hour ÷ kg/h de rendement, adjusted for automation grade.
• Pièces d'usure: annual spend on screw elements, blocs à pétrir, barils, and screens ÷ annual kilograms produced.
• Cooling and utilities: chiller energy and water cost allocated per kilogram.

Running this calculation across two or three candidate machines frequently reverses the ranking the sticker price suggests. A machine that costs more up front but draws less power per kilogram and runs

Assistance après-vente, Garantie, and Service

D'après mon expérience, the purchase price of a twin screw extruder tells you very little about its true cost of ownership. What determines whether a machine becomes a profit center or a recurring headache is everything that happens after the freight arrives: the warranty terms, the speed of technical support, and how quickly spare parts reach your floor. When I evaluate any Twin Screw Extruder Wholesale supplier, I weight after-sales commitments almost as heavily as the spec sheet, because a stalled compounding extruder with a six-week parts lead time can erase a year of margin.

Warranty Length and Coverage Scope

Warranty terms across this category vary more than buyers expect. I treat the headline duration as only the starting point and read the coverage scope line by line. The questions I always resolve before signing are these:

• Does coverage span the full drivetrain — the extruder gearbox, high-torque shaft, et moteur — or only the control cabinet and PLC?
• Are wear parts such as the screw element, kneading block, and barrel liners explicitly excluded, as they usually are?
• Does the warranty clock start at shipment or at commissioning? On a sea shipment, that difference can quietly consume two months of cover.
• Who pays freight on a warranted replacement part, and under which Incoterm?

For wear surfaces, I expect exclusions. The screw and barrel are consumables on any double screw extruder, and no reputable manufacturer warrants them against abrasive PVC or glass-filled compounds. What I do insist on is a clear, written statement of expected service life so I can budget replacements rather than be surprised by them.

Remote and On-Site Technical Support

The most useful support distinction I draw is between remote diagnostics and on-site service. Modern PLC-controlled units allow a supplier's engineers to log in, read fault histories, and adjust parameters without travel, which resolves a large share of issues within hours. On-site support matters most during installation and for mechanical faults that remote access cannot reach.

Before committing to a Twin Screw Extruder Wholesale manufacturer, I confirm three things: whether remote support is included or billed hourly, the realistic response window in my time zone, and the cost and visa logistics of dispatching a technician for an on-site visit. For overseas factories, on-site service often carries travel, accommodation, and day-rate charges that should be negotiated into the contract rather than discovered later.

Spare-Parts Lead Times

Spare-parts lead time is the variable I find most often ignored at the point of sale and most painful afterward. A specialized parts ecosystem does exist — dedicated suppliers stock screw-and-barrel assemblies and other extruder machine parts as standalone catalog items — but matching geometry to your specific machine takes time. To protect uptime, I ask every supplier for a tiered breakdown: which parts ship from stock, which are made to order, and the quoted lead time for each. For any plastic pelletizing machine running production schedules, I recommend buying a starter kit of fast-wearing screw elements and a spare screen changer cartridge up front, when freight can be consolidated with the machine.

Training and Documentation in Your Language

A capable machine is only as good as the operators running it. I require operation and maintenance documentation in my team's working language, not a machine-translated PDF, and I confirm whether operator training is included, offered remotely, or charged separately. For an industrial extrusion machine with vacuum degassing, side feeder, and melt-pump options, the commissioning recipe work is where training pays for itself — properly trained operators reach stable output and quality far faster.

Top Twin Screw Extruder Brands to Benchmark Against

I do not benchmark brands to find a single winner. I benchmark them to build a frame of reference — a way to judge whether a wholesale quote's spec claims are credible and whether the price reflects genuine value or simply a thinner build. Twin screw extruders span plastics, médicaments, transformation des aliments, and chemicals precisely because of their precision and versatility, and the brand tiers reflect different positions on the cost-versus-capability curve.

Premium Brands: Thermo-pêcheur, KraussMaffei, Berstorff, et Maris

The premium tier sets the engineering ceiling. Thermo Fisher is the reference point for laboratory and pharmaceutical co-rotating twin screw systems, where tight tolerances and validated processes matter more than throughput. KraussMaffei and Berstorff anchor high-output compounding and recycling; both appear regularly in used-machine inventories alongside Maris, with outputs ranging from 100 kg/h jusqu'à 4,000 kg/h according to Euro-Machinery's twin screw extruders category (2024). Maris is well regarded in masterbatch making and engineering-polymer compounding. When I read a wholesale spec sheet promising premium-brand throughput at a fraction of the price, these names are my reality check on what high-torque shafts, hardened barrels, and generous L/D ratios actually cost to build.

Volume Manufacturers: JWELL and China-Based Factories

The volume tier is where most wholesale sourcing happens. JWELL is a strong benchmark here — its conical counter-rotating twin screw extruders handle both soft and rigid PVC pelletizing with downstream die-face cutting and cooling, per JWELL Machinery (2024), which makes it a natural reference for any PVC pipe extrusion line or recycling project. Beyond named brands, the broader China-based factory base is deep: Made-in-China.com répertorie plus de 74,746 Vente en gros de produits d'extrudeuse à double vis d'occasion (2024), and its supplier filters distinguish manufacturer/factory, société commerciale, and group corporation business types with OEM/ODM capacity. That depth is an advantage, but it also means spec claims need independent verification, which is exactly what the premium benchmarks let me do.

Comparing Brand Value Against Wholesale Price

The table below frames how I read these tiers against the wide price reality of this market — depuis des listes de petits composants de moins de 2 $ US par unité à plus de 200 000 $ US par ensemble, comme documenté dans la liste de gros Accio (2026).

Étage	Marques représentatives	Tranche de prix indicative (par ensemble)	Plage de sortie typique	Meilleur ajustement
Prime / laboratoire	Thermo-pêcheur	High à cinq ou six chiffres USD	À l'échelle du laboratoire, 50–600 traitement tr/min	Pharmaceutique, R.&D, processus validés
Prime / production	KraussMaffei, Berstorff, Maris	Six chiffres USD neuf	100–4,000 kg/heure	Composition de gros volumes, recyclage
Tome nouveau	BIJOU, Usines basées en Chine	~15 000 $ US–$80,000+	~10–150 kg/h et plus	PVC, granulation, lignes clé en main
Utilisé / secondaire	Mixte (y compris. revente premium)	~25 000 $ US (PVC conique d'occasion) et plus	100–4,000 kg/heure	Capacité limitée par le budget

Sources: Euro-Machines (2024); Accio wholesale listing (2026); Made-in-China.com a utilisé une extrudeuse à double vis (2024); Nouvelles machines en plastique, Bahadurgarh (2024), qui énumère un 100 kg/h, 80 Unité semi-automatique kW à environ Rs 15,00,000 par pièce. Les fourchettes de prix sont indicatives et dépendent de la configuration.

Utiliser des références pour juger les réclamations relatives aux spécifications

Lorsqu'un devis de gros revendique un 40+ L/D ratio, vis co-rotatives s'engrenant, dégazage sous vide, et un changeur d'écran lourd à un prix bien en dessous de la bande de volume, Je recoupe le régime de la boîte de vitesses et la puissance du moteur (kW) against what premium builders charge for comparable torque density. The screw diameter naming convention common to wholesale lineups, with outputs from roughly 10 kg/h à 150 kg/h per twinscrewgranulator.com (2024), gives a sanity check: output that far exceeds what a stated screw diameter and motor should physically deliver is a red flag worth investigating before purchase.

Negotiation and Volume Discount Strategies

Negotiation in this category is rarely about shaving a few percent off a single machine. The real leverage comes from how you structure the whole deal — unités, accessories, fret, garantie, and the relationship that follows. I approach every Twin Screw Extruder Wholesale negotiation as the opening of a multi-year supply relationship rather than a one-time transaction, because that framing changes what a supplier is willing to concede.

Leveraging Multi-Unit Orders

The clearest lever is volume. Suppliers price marginal units far more aggressively than the first one because tooling, ingénierie, and setup costs are already absorbed. When I have a multi-line rollout, I quote the full program up front and ask for tiered pricing tied to committed quantities. Even when I cannot commit to all units immediately, a phased order with a stated forecast often unlocks the volume tier on the first batch, provided I am transparent about the schedule.

Bundling Accessories and Spare Parts

The second lever is the bundle. A bare extruder rarely runs production alone — it needs a side feeder, a melt pump, un changeur d'écran, downstream pelletizing or cooling, and a stock of wear parts. I negotiate these as a package rather than line items, because a supplier protecting a discount on the core machine will often concede generously on accessories and spares to keep the headline price intact. Folding a starter set of screw elements and kneading blocks into the deal also solves the spare-parts lead-time risk discussed earlier, at near-marginal cost.

Negotiating Freight, Garantie, and Training Inclusions

The third lever is the set of terms buyers too often accept as fixed. I push to bring freight Incoterms, extended warranty, remote support hours, and operator training inside the negotiated scope. For overseas turnkey extrusion production line purchases, converting an EXW quote into a clear delivered cost — and getting commissioning and a defined block of training included — frequently delivers more value than a price cut, because it removes hidden landed costs that would otherwise surface after the machine ships.

Building Long-Term Supplier Relationships

The most durable discount strategy I know is repeat business handled well. Suppliers reserve their best pricing, fastest parts allocation, and priority support for accounts they trust to pay on agreed milestones and order again. I formalize this by aligning payment milestones with QC inspection gates, honoring the terms precisely, and signaling future demand. Over several orders, that track record compounds into pricing and service no first-time buyer can negotiate. For background on supplier landscapes and configuration ranges as you prepare to negotiate, le Made-in-China.com twin screw extruder listings et le Euro-Machinery used twin screw extruder category are useful reference points for benchmarking both new and used-equipment pricing.

Common Mistakes to Avoid When Buying Wholesale

Over the years I have watched capable buyers make the same handful of errors when sourcing a twin screw extruder at wholesale. The machine itself is rarely the problem. The trouble usually starts with the assumptions that surround the purchase: what the quoted price actually covers, what happens between the factory floor and your loading dock, and how the equipment behaves once it is running on your shop floor. The mistakes below are the ones I see repeatedly, and each one carries a measurable cost.

Ignoring Total Landed Cost in Favor of Unit Price

The single most expensive error I encounter is treating the quoted screw extruder price as the final number. A double screw extruder advertised at an attractive figure can land at your facility 20 à 40 percent higher once freight, assurance maritime, droits d'importation, courtage en douane, manutention portuaire, and inland transport are added. The wholesale market itself signals how wide this range can be: published listings span from under US $2 per unit at extreme volume to over US $200,000 per set for industrial systems, selon une liste d'extrudeuses à double vis de laboratoire de plastique en gros Accio (2026, accio.com). When the headline number can vary by five orders of magnitude, the unit price alone tells you almost nothing. I always rebuild the quote into a total landed cost model before I compare two suppliers, because a higher ex-works price with favorable Incoterms frequently wins on the final delivered figure.

Skipping Pre-Shipment Inspection

Wholesale procurement, especially cross-border, removes you from the production line. Skipping a pre-shipment inspection means you are trusting that the extruder screw and barrel, the gearbox, the kneading block configuration, and the control panel all match your specification sheet. D'après mon expérience, the cost of a third-party inspection is trivial against the cost of receiving an industrial extrusion machine that fails commissioning. I treat inspection as non-negotiable: verify the L/D ratio, confirm screw diameter and screw element layout, run a no-load motor test, and photograph the nameplate against the agreed spec before the unit leaves the factory.

Overlooking Voltage and Electrical Compatibility

This one quietly derails commissioning more often than any mechanical fault. Extruder motor power, expressed in kW, must be matched to your facility's voltage, phase, and frequency. UN 100 kg/h, 80 kW semi-automatic twin screw extruder priced around Rs 15,00,000 par pièce, per New Plast Machinery, Bahadurgarh (2024, indiamart.com), is built to a regional electrical standard that may not match yours. I always confirm voltage, fréquence (50 contre 60 Hz), and phase in writing, and I budget for a transformer or VFD reconfiguration if the supplier's standard differs from my grid.

Underestimating Spare Parts and Downtime Costs

A compounding extruder is a consumable-intensive machine. Éléments à vis, blocs à pétrir, doublures de baril, screen changer components, and melt pump seals all wear. Buyers who negotiate only the machine price and ignore the spare parts package pay for it later in unplanned downtime. Before I commit, I request a recommended spares list with pricing and lead times for the screw and barrel set in particular, since these are the wear items that determine output kg/h consistency. Sourcing references such as a dedicated screw and barrel parts factory (twinscrewextruder-parts.com) confirm that aftermarket parts are widely available, but lining up a supplier before a failure beats scrambling during one.

Your Wholesale Twin Screw Extruder Sourcing Checklist

The catalogs I reviewed while researching this guide are full of specifications but offer almost no guidance on how to actually run a purchase. The checklist below is the process I use, sequenced so that each step de-risks the next. Work through it in order rather than jumping to supplier shortlists, because the early definition stage prevents most of the mistakes described above.

Étape 1: Define Application, Matériel, and Target Output First

Before contacting a single twin screw extruder manufacturer, I document three things. D'abord, the application: am I building a PVC pipe extrusion line, a masterbatch making operation, a plastic recycling extruder, or a pet food extruder? Deuxième, the material and its processing behavior, which drives the choice between a co-rotating twin screw for compounding and a counter-rotating or conical twin screw extruder for rigid and soft PVC pelletizing with downstream die-face cutting and cooling, as configured by JWELL Machinery (2024, jwell.com). Troisième, the target output in kg/h. Wholesale model lineups commonly use screw diameter as the naming convention, with output running from roughly 10 kg/h à 150 kg/h per twinscrewgranulator.com product specifications (2024, twinscrewgranulator.com), so fixing your output target immediately narrows the candidate models.

Étape 2: Shortlist and Vet Suppliers Against Certification Criteria

With a clear specification, I build a shortlist and filter it against business type and certification. Major marketplaces distinguish between manufacturer/factory, société commerciale, et types d'entreprises de sociétés de groupe, avec capacité OEM/ODM signalée séparément, per Made-in-China.com search filters (2024, made-in-china.com). I prioritize direct manufacturers when I want control over the build and a trading company only when it adds genuine consolidation value. On certification, common listings include CE, ISO9001:2008, ISO9001, BPF, et UL (Taxonomie des certifications Made-in-China.com, 2024). I match the certification to the application: GMP for a pharmaceutical experimental extruder, CE for European deployment, UL for North American electrical compliance.

Étape 3: Request Samples, Quotes, and Clear Incoterms

For a low-cost lab scale twin screw extruder I request a sample or a video of a trial run on my material. For an industrial unit, a sample is impractical, so I require a documented trial-run report instead. Every quote must specify the Incoterm explicitly. The difference between EXW, GOUSSET, CIF, and DAP determines who controls and pays for each leg of the journey, and it is the lever that turns unit price into landed cost. I ask each supplier to quote on the same Incoterm so the comparison is genuine.

Étape 4: Confirm QC, Payment Milestones, and After-Sales Terms

Avant de signer, I lock down four contractual elements. Contrôle de qualité: the inspection point and acceptance criteria. Payment milestones: I avoid full prepayment and structure payments against deposit, pre-shipment inspection pass, et livraison. After-sales: warranty term, disponibilité des pièces de rechange, assistance à la mise en service à distance, and response time. Documentation: the spec sheet, attestations, and electrical compatibility confirmation attached to the contract. These terms are exactly where the catalogs fall silent, et c'est là que la plupart des conflits sont gagnés ou perdus.

Foire aux questions sur la vente en gros d'extrudeuses à double vis

Ce sont les questions que me posent le plus souvent les acheteurs qui entrent pour la première fois sur le marché de gros., ainsi que les réponses que je donne sur la base des données actuelles du marché.

Quel est le MOQ typique pour une commande en gros d'extrudeuse à double vis?

Pour machines industrielles complètes, la quantité minimale de commande est souvent un seul ensemble, which is why wholesale listings quote prices "per set" or "per piece." Les marchés secondaires et de laboratoire sont suffisamment profonds pour que l'achat d'une unité unique soit standard. Remises sur volume et sub-US $2 les chiffres par unité n'apparaissent que pour les plus petits produits expérimentaux ou au niveau des composants en quantités très élevées, not for production extruders.

What lead times should I expect?

Lead time depends on whether you buy new or used. A used machine can ship within days of payment because it already exists. A new build, particularly an OEM/ODM configuration with a custom screw element and kneading block layout, typically runs several weeks to a few months. I always get the lead time in writing and tie it to a payment milestone.

How is wholesale pricing structured?

Pricing scales with screw diameter, output kg/h, puissance du moteur en kW, and automation level. A lab unit with a 25 vis mm, 7.5 Moteur kW, 50 kg/h de rendement, Contrôle par API, and vacuum degassing sits at the low end (Liste des laboratoires Accio, 2026), while a 100 kg/h, 80 kW production machine runs around Rs 15,00,000 (Nouvelles machines en plastique, 2024). The table below summarizes representative wholesale tiers.

Étage	Representative spec	Prix ​​indicatif	Source
Laboratoire / experimental	25 vis mm, 7.5 kW, 50 kg/heure, API, dégazage sous vide	Low end of wholesale range	Action (2026)
Used conical (Tuyau en PVC)	Conique contrarotatif, soft/rigid PVC	~US $25,000 par ensemble	Fabriqué en Chine.com (2024)
New production	100 kg/h, 80 kW, semi-automatic	~Rs 15,00,000 par pièce	Nouvelles machines en plastique (2024)
Industriel / rendement élevé	High-torque shaft systems, jusqu'à 4,000 kg/heure	Up to US $200,000+ par ensemble	Euro-Machines (2024); Action (2026)

Should I buy new or used?

This is the decision framework competitors rarely provide. I choose used when budget is the binding constraint, when I need fast delivery, or when the application is forgiving. The secondary market is genuinely deep: Made-in-China.com répertorie plus de 74,746 Vente en gros de produits d'extrudeuse à double vis d'occasion (2024), and Euro-Machinery's used inventory spans recognized brands such as Berstorff, KraussMaffei, and Maris with outputs from 100 kg/h à 4,000 kg/heure (2024, euro-machinery.com). I buy new when I need a warranty, contrôle précis du processus, a specific certification, or a turnkey extrusion production line with full after-sales support. For a used purchase, pre-shipment inspection of the screw and barrel wear is even more critical than it is for new equipment.

Which certifications and compliance marks should I require?

As a quick reference: CE for sale and operation in the European Economic Area, UL for North American electrical safety, ISO9001 (including the older ISO9001:2008) as a manufacturer quality-system signal, and GMP for any pharmaceutical or food-contact application. These are the marks commonly listed across wholesale platforms (Taxonomie des certifications Made-in-China.com, 2024). I require the actual certificate documents, not just a checkbox on a listing, and I attach them to the purchase contract.

How do I avoid the most common wholesale mistakes?

Compare on total landed cost rather than unit price, insist on pre-shipment inspection, confirm voltage and electrical compatibility in writing, and budget for spare parts and the intermeshing twin screw wear items from day one. These four habits address the failures I see most frequently.

Where can I find reliable wholesale suppliers?

Reliable supply falls into three channels. Large B2B marketplaces aggregate manufacturers, trading companies, and group corporations with searchable certification and business-type filters. Specialist new-equipment manufacturers publish detailed spec lineups for compounding and granulating machines. Dedicated used-equipment dealers and auction platforms hold deep inventory of branded secondary machines. Across all three, the entity that I treat as the safest counterpart is a verified direct manufacturer with the certifications my application requires and a documented after-sales structure, because that combination is what protects the purchase long after the machine arrives.

What Is Twin Screw Extruder Wholesale and Why It Matters for B2B Buyers

When I source extrusion equipment for procurement teams, I define twin screw extruder wholesale as the bulk or trade-channel purchase of double screw extrusion machines directly from manufacturers, usines, or trading companies rather than through single-unit retail. The distinction matters because the wholesale channel changes everything about how you negotiate price, quantité minimum de commande, personnalisation, et support après-vente.

Définition: What You Are Actually Buying

A twin screw extruder uses two intermeshing screws rotating inside a barrel to convey, fondre, mélanger, and pressurize material. D'après mon expérience, the wholesale conversation begins with three architectural choices. A co-rotating twin screw configuration is the workhorse for compounding and masterbatch making extrusion because the screws turn in the same direction and deliver strong distributive mixing. A counter-rotating twin screw runs the screws in opposite directions for high-pressure, low-shear work. A conical twin screw extruder, where the screw diameter tapers along its length, is the standard for soft and rigid PVC pelletizing with downstream die-face cutting and cooling, as JWELL Machinery describes for its PVC conical twin-screw pelletizing line (JWELL Machinery, 2024).

Acheter un fabricant d'extrudeuse à double vis The specifications that drive a wholesale quote are the screw diameter, le rapport L/D (the ratio of screw length to diameter), the extruder motor power in kW, and the rated extruder output in kg/h. Wholesale model lineups commonly use screw diameter as the naming convention, with output ranging from roughly 10 kg/h à 150 kg/h across a single catalog (twinscrewgranulator.com, 2024). Inside the barrel, the kneading block and individual screw element segments are configurable, which is why two machines with identical screw diameters can behave very differently.

Contexte du marché: How Deep the Wholesale Market Runs

The wholesale market for these machines is large and layered. Made-in-China.com alone lists over 74,746 Vente en gros de produits d'extrudeuse à double vis d'occasion, which signals a deep secondary market alongside new equipment (Fabriqué en Chine.com, 2024). Pricing reflects that breadth. Wholesale unit prices range from under US $2 per unit at scale for small components or accessory listings to over US $200,000 per set for full industrial systems (Action, 2026). For context across the spectrum:

• A wholesale lab twin screw extruder with a 25mm screw, 7.5Moteur kW, 50 kg/h de rendement, Contrôle par API, and vacuum degassing sits at the entry of the range (Action, 2026).
• Used conical twin screw PVC pipe extruders are quoted around US $25,000 par ensemble (Fabriqué en Chine.com, 2024).
• An Indian-made 100 kg/h, 80kW semi-automatic twin screw extruder is priced around Rs 15,00,000 par pièce (Nouvelles machines en plastique, Bahadurgarh, 2024).

Used-machine inventory adds another tier, spanning brands like Berstorff, KraussMaffei, and Maris with outputs from 100 kg/h jusqu'à 4,000 kg/heure (Euro-Machines, 2024). That range is the reason I always tie a buyer's target output to a price band before we shortlist any twin screw extruder for sale.

Key Applications That Justify the Investment

Les extrudeuses bivis servent les plastiques, médicaments, transformation des aliments, et produits chimiques en raison de leur précision, versatilité, et efficacité (Haut 20 Fabricants d'extrudeuses à double vis, 2025). In practical terms, I see the same machine class deployed as a twin screw granulator for compounding, as the core of a PVC pipe extrusion line, as a plastic recycling extruder, as a pet food extruder, and as a pharmaceutical compounding extruder. Pharmaceutical experimental extruders, par exemple, operate across a 50-600 rpm range for lab-scale processing (China laboratory twin screw extruder factory, 2024). The intermeshing twin screw design is what lets one platform cover so many jobs.

Why the Wholesale Channel Matters for B2B Buyers

Here is the gap I see most often: catalogs list specifications but do not translate them into purchasing decisions, and almost none explain the full wholesale buying process. Buying wholesale is not just a lower sticker price. It is access to OEM/ODM customization, volume-based payment milestones, and a direct line to the factory engineering team that built your extruder screw and barrel. It also exposes you to risks a retail purchase would not, which is exactly why supplier selection deserves its own discipline.

How to Choose the Right Twin Screw Extruder Wholesale Supplier

Choosing a Twin Screw Extruder Wholesale supplier is where most of the value, et la plupart des risques, vies. I evaluate suppliers across business type, capacité technique, attestation, and commercial terms before I let total landed cost decide between finalists.

Vendor Evaluation: Know Who You Are Buying From

Supplier filters on the major B2B platforms distinguish manufacturer/factory, société commerciale, et types d'entreprises de sociétés de groupe, with OEM/ODM capacity noted separately (Fabriqué en Chine.com, 2024). This classification is the first thing I check. A manufacturer gives you direct engineering access and better margins on customization of the kneading block, side feeder, pompe à fonte, changeur d'écran, and high-torque shaft. A trading company can broaden selection but adds a markup and a communication layer. Neither is wrong, but you should know which one you are paying.

Certifications That Carry Weight

Common certifications listed across the wholesale market include CE, ISO9001:2008, ISO9001, BPF, et UL (Fabriqué en Chine.com, 2024). I treat CE as the baseline for any machine shipping to Europe, GMP as non-negotiable for pharmaceutical and food extrusion, and UL as the marker for North American electrical compliance. I always ask for the actual certificate number and verify it rather than accepting a logo on a brochure.

Drapeaux rouges dont je m'éloigne

• Quotes with no breakdown of screw diameter, L/D ratio, extruder motor power kW, and extruder output kg/h. Vague specs hide vague machines.
• Certification logos with no verifiable numbers.
• Refusal to allow a factory audit or third-party inspection.
• Prices far below the market bands above with no explanation. An industrial extrusion machine priced like a component listing is a sourcing-error risk.
• No clarity on whether the unit is new, utilisé, or refurbished, and no service or parts commitment for the extruder gearbox and wear components.

Liste de contrôle de diligence raisonnable

Before issuing a purchase order, I work through this checklist with the buyer:

1. Confirm business type (manufacturer vs trading company) and years of operation.
2. Validate certifications (CE, ISO9001, BPF, UL) by number.
3. Request reference installations matching your output target and material.
4. Obtain a full technical datasheet: configuration des vis, L/D ratio, motor kW, dégazage sous vide, pompe à fonte, changeur d'écran, control system.
5. Define MOQ, Incoterms (GOUSSET, CIF, or DAP), and payment milestones (typical structure is a deposit, a pre-shipment balance against inspection, and a retention against commissioning).
6. Arrange QC inspection before shipment, ideally a factory acceptance test under load.
7. Calculate total landed cost: fret, devoirs, conversion de tension, et mise en place.
8. Confirm spare parts availability and warranty terms.

New vs Used vs OEM/ODM: A Decision Framework

One framework competitors rarely provide is the new/used/OEM choice laid out against what actually matters in a B2B purchase.

Critère	Nouveau (Direct usine)	Utilisé / Secondary Market	OEM/ODM Customized
Typical price band	NOUS $25,000 à $200,000+ par ensemble (Action, 2026)	~US $25,000 per set for used PVC lines (Fabriqué en Chine.com, 2024)	New-build premium plus engineering fees
Délai de mise en œuvre	Modéré (build-to-order)	Rapide (en stock)	Le plus long (conception + construire)
Output flexibility	Catalog range ~10 to 150 kg/heure (twinscrewgranulator.com, 2024)	Large, jusqu'à 4,000 kg/h on brand units (Euro-Machines, 2024)	Tailored to spec
Personnalisation	Limited to standard options	As-is	Complet (éléments de vis, side feeder, contrôles)
Risk profile	Low with verified supplier	Plus haut; inspect wear on screw and barrel	Low technically, higher on lead-time slippage
Best for	Standard compounding or pelletizing	Budget-constrained or proven processes	Unique materials or formulations

I steer buyers toward used equipment when the process is well understood and downtime tolerance is high, and toward OEM/ODM when the material or formulation falls outside standard machine envelopes. For most first-time buyers, factory-direct new equipment from a verified twin screw extruder manufacturer is the lowest-regret choice.

Find Wholesale Suppliers of Twin Screw Extruders for B2B Bulk Purchase

Once the evaluation framework is set, the practical question is where to actually find suppliers and how to run the bulk purchase cleanly. I split sourcing into channels, then layer in the commercial mechanics that determine whether a wholesale deal succeeds.

Key Considerations Before You Source

I start every sourcing project by fixing three numbers: target output in kg/h, the material to be processed, and the maximum total landed cost. Those three constrain the search far better than a screw diameter alone. From there I match the requirement to a channel. Global B2B marketplaces such as Made-in-China.com and HiSupplier carry the broadest manufacturer and trading-company selection, while specialist used-equipment platforms like Euro-Machinery and Bid on Equipment list branded secondary inventory with documented outputs (Euro-Machines, 2024).

Practical Tips for Bulk Purchase

• Confirm voltage and frequency early. A machine built for 380V/50Hz may need conversion for a 480V/60Hz plant, and that cost belongs in the quote, not the surprise column.
• Negotiate payment against milestones, not calendar dates. Tie the pre-shipment balance to a passed factory acceptance test on the extruder gearbox, moteur, et système de contrôle.
• Specify Incoterms explicitly. The gap between FOB and DAP can be a five-figure swing on a heavy turnkey extrusion production line.
• Budget for commissioning. Installation, alignement, and a supervised first run protect a six-figure asset.
• Inspect wear surfaces on any used extruder screw and barrel. These are the most expensive parts to replace and the easiest to misrepresent.

Contexte de l'industrie: Reading the Wholesale Landscape

The breadth of this market is both an advantage and a trap. Avec plus 74,746 used twin screw extruder listings on a single platform (Fabriqué en Chine.com, 2024) and price points spanning under US $2 to north of US $200,000 (Action, 2026), comparison shopping without a fixed specification target leads to noise rather than insight. The lab-scale tier illustrates the point well: a wholesale lab unit at 25mm screw, 7.5kW, et 50 kg/h with PLC and vacuum degassing serves R&D and small-batch pharma, while regional manufacturers like New Plast push 100 kg/h, 80kW production machines (Nouvelles machines en plastique, 2024). Knowing which tier you belong in is what turns a sprawling wholesale catalog into a shortlist.

Recommended Starting Points

For active sourcing, I point buyers to the established manufacturer directory at Made-in-China.com's twin-screw extruder category, which exposes the business-type and certification filters discussed above, and to Euro-Machinery's used twin screw extruder inventory for branded secondary-market units. I treat these as research entry points, then move the conversation off-platform to direct negotiation, factory audit, and a documented purchase agreement before any payment changes hands.

Compare wholesale prices for twin screw extruders across manufacturers

When I benchmark wholesale prices for twin screw extruders, the first thing I tell buyers is that "price" only becomes meaningful once you anchor it to screw diameter, sortir, and condition. The spread is enormous. I have seen marketplace listings advertise units for under US $2 each at bulk scale, while a fully configured compounding extruder can exceed US $200,000 per set on the same platform (Liste des extrudeuses à double vis de laboratoire en plastique Accio en gros, 2026, https://www.accio.com/plp/wholesale-plastic-lab-twin-crew-extruder-1-set). That four-order-of-magnitude gap is not a pricing error. It reflects how broadly the term "twin screw extruder wholesale" gets applied, from desktop lab equipment to 4,000 kg/h industrial lines.

What actually drives the screw extruder price

D'après mon expérience, four variables explain most of the price you will be quoted. Screw diameter and L/D ratio set the throughput envelope. Motor power in kW and gearbox torque rating govern how aggressively you can compound. Configuration depth, meaning whether the machine ships with a side feeder, pompe à fonte, changeur d'écran, and vacuum degassing, swings the bill of materials significantly. Enfin, condition, new versus used versus reconditioned, can cut the headline number by half or more.

To make this concrete, here is how representative wholesale offers line up across manufacturers and channels. I have normalized each entry to the spec the seller published so you can compare like with like rather than chasing a single misleading number.

Source / canal	Taper	Representative spec	Condition	Prix ​​indicatif
Accio wholesale lab listing (2026)	Lab scale twin screw extruder	25 vis mm, 7.5 kW, ~50 kg/h, API + dégazage sous vide	Nouveau	Niveau d'entrée; annonces groupées allant de moins de 2 $ US/unité à des ensembles de configurations plus élevées
Nouvelles machines en plastique, Inde (2024)	Extrudeuse de composition semi-automatique	100 kg/h, 80 kW	Nouveau	~Rs 15,00,000 par pièce (≈ NOUS $18,000)

Lire le tableau sans se tromper

Le conseil pratique que je donne à chaque responsable des achats est d'arrêter de comparer les prix des étiquettes et de commencer à comparer le coût par kg/h de production fiable.. Un États-Unis $18,000 Machine indienne évaluée à 100 kg/h et un US $25,000 ligne conique utilisée, regardez de près sur le papier, but the conical counter-rotating geometry is purpose-built for soft and rigid PVC pelletizing with downstream die-face cutting and cooling (Ligne de granulation conique à double vis en PVC JWELL Machinery, 2024, https://www.jwell.com). If your feedstock is a heat-sensitive PVC compound, the cheaper co-rotating compounder is not actually a substitute. Match the screw geometry to the polymer before you let price drive the decision.

Industry context matters here too. Twin screw extruders span plastics, médicaments, transformation des aliments, and chemicals precisely because their modular screw elements and kneading blocks deliver precision and versatility across very different viscosities (Haut 20 Fabricants d'extrudeuses à double vis, 2025, https://www.example-blog.com/twin-screw-extruder-manufacturers). A pharmaceutical lab extruder running 50–600 rpm carries validation overhead that a plastics pelletizer never will (Liste des usines d'extrudeuse à double vis de laboratoire en Chine, 2024). That overhead is baked into the wholesale price, so cross-industry price comparisons rarely hold.

Identify reliable China-based twin screw extruder manufacturers

Most wholesale twin screw extruder supply still routes through China, and the depth is real: Made-in-China.com alone lists more than 74,746 Vente en gros de produits d'extrudeuse à double vis d'occasion, which tells you the secondary market is mature and well-stocked (Made-in-China.com a utilisé une extrudeuse à double vis, 2024, https://m.made-in-china.com/wholesale/used-twin-screw-extruder_2.html). The challenge is not finding suppliers. It is separating a genuine twin screw extruder manufacturer from a trading company reselling someone else's barrels and screws.

Read the business-type filter first

Before I email a single supplier, I use the marketplace business-type filters. Made-in-China.com explicitly distinguishes manufacturer/factory, société commerciale, and group corporation, and flags OEM/ODM capacity (Filtres de recherche pour extrudeuse à double vis Made-in-China.com, 2024, https://www.made-in-china.com/products-search/hot-china-products/Twin-screw_Extruder.html). For most buyers I steer toward verified manufacturer/factory accounts, because that is where you get direct control over the extruder screw and barrel metallurgy, gearbox sourcing, and high-torque shaft tolerances. Trading companies have a place when you want one contract to bundle a turnkey extrusion production line from multiple makers, but you accept a margin and a layer of distance from quality control.

Use certifications as a filter, not a guarantee

Certifications narrow the field quickly. The common taxonomy I look for includes CE, ISO9001:2008, ISO9001, BPF, et UL (Taxonomie des certifications Made-in-China.com, 2024, https://www.made-in-china.com/products-search/hot-china-products/Twin-screw_Extruder.html). Ma règle de base: ISO9001 signals a documented process, CE matters for European installation, UL matters for North American electrical compliance, and GMP is non-negotiable if you are buying a pharmaceutical or food extruder. A supplier that cannot produce the actual certificate PDF on request, rather than a logo on a listing, gets dropped.

A short factory-vetting checklist

This is the gap I see competitors leave wide open. Catalogs publish specs but never tell you how to vet the company behind them. Here is the sequence I run:

• Confirm business type and ask for the business license; cross-check the registered name against the marketplace account.
• Request three reference installations with the same screw diameter and output you need, ideally in your target industry.
• Ask whether the gearbox, moteur, and screen changer are made in-house or bought in, and from whom.
• Request a live or recorded factory walkthrough showing screw element machining and assembly, not just a finished-goods warehouse.
• Verify spare-parts lead time for screw elements, blocs à pétrir, et des barils; a manufacturer that cannot quote a wear-part replacement is a red flag.

For homework, the marketplace and supplier directories I lean on most are Made-in-China.com and a focused manufacturer catalog such as the twin screw granulator product line, which documents output from roughly 10 kg/h à 150 kg/h using screw diameter as the naming convention (spécifications du produit twinscrewgranulator.com, 2024, twinscrewgranulator.com). That naming convention is a quick literacy test: a credible manufacturer can map a model number straight to screw diameter, L/D ratio, and rated kg/h without hesitation.

Nouveau, utilisé, or OEM/ODM

Reliability also depends on which channel fits your risk tolerance. I frame it as three lanes. New from a verified factory gives you warranty and current screw geometry but the highest price. Used from a broker like Euro-Machinery puts premium European brands such as Berstorff, KraussMaffei, and Maris within reach at outputs from 100 kg/h à 4,000 kg/heure, with the tradeoff of buying wear history (Euro-Machines, 2024, Euro-Machines). OEM/ODM suits buyers who need a specific compounding extruder configuration or private branding and have the volume to justify tooling. Decide the lane before you negotiate, because each one changes what "reliable" even means.

Understand minimum order quantity (MOQ) for twin screw extruder wholesale

MOQ for capital equipment behaves very differently from MOQ for consumables, and this trips up first-time buyers constantly. Pour machines industrielles complètes, the practical MOQ is often a single set. Listings quote prices "per set" and "per piece" precisely because one unit is a real order at this price point (Fabriqué en Chine.com, 2024, https://m.made-in-china.com/wholesale/used-twin-screw-extruder_2.html; Nouvelles machines en plastique, 2024, https://www.indiamart.com/new-plast-machinery/extruder-machine.html). The sub-US $2 "wholesale" figures you see attached to lab units almost always refer to component-level or bulk-quote pricing tiers, not a one-machine purchase. Read the unit of measure carefully before you assume a bargain.

Where MOQ actually bites

The real MOQ negotiation happens on spare parts and OEM configurations. If you commission a custom screw and barrel profile or a private-label run, the supplier needs minimum volume to amortize tooling. For wear parts, éléments de vis, blocs à pétrir, et des barils, I always negotiate the spares package into the original machine order, because ordering a single element later often triggers a higher per-piece price or a minimum-batch requirement. Bundling these at purchase is the single most effective MOQ lever I use.

MOQ is only half the cost story

Here is what catalogs almost never address, and what I insist clients model before signing: total landed cost. The machine price is the beginning, not the end. A realistic landed-cost build-up looks like this:

• Ex-works machine price plus any spare-parts bundle.
• Incoterms exposure: whether you are quoted FOB, CIF, or DAP changes who pays ocean freight and insurance.
• Import duties and VAT in your jurisdiction.
• Voltage and frequency conversion if the extruder motor power is wired for a different grid.
• Installation, mise en service, et formation des opérateurs, especially for a turnkey extrusion production line.
• Inland freight and rigging for a multi-ton industrial extrusion machine.

D'après mon expérience, fret, devoirs, and installation can add 15 à 40 percent on top of the ex-works number for an overseas purchase. Un États-Unis $25,000 used conical PVC line can quietly become a US $32,000 to US $35,000 commitment once it is energized on your floor. Build that into the comparison so a low MOQ on an attractive machine does not mask a high total cost.

Payment milestones and QC: protecting a single-unit order

Because the practical MOQ is often one expensive set, payment structure does the work that volume cannot. The structure I prefer ties money to verifiable progress: a deposit to start production, a payment after a pre-shipment factory acceptance test where you watch the machine run your material to rated output, and a balance after delivery or successful commissioning. I treat the pre-shipment inspection as mandatory for any twin screw extruder for sale at this value, whether through a third-party QC firm or my own engineer on site. For lab-scale units, a documented run confirming the rated 50 kg/h output and PLC plus vacuum degassing function is enough; for an industrial compounding extruder, I want a sustained run at full kg/h with the side feeder, pompe à fonte, and screen changer in the loop.

Put together, the buying process I recommend is concrete: confirm the supplier business type and certifications, lock the screw geometry to your polymer, negotiate the spares package into the MOQ, model total landed cost including Incoterms and voltage, and gate payment on a pre-shipment QC inspection. That sequence is what turns a confusing wholesale price range into a defensible purchasing decision.

Bringing It All Together: Sourcing With Confidence in 2025

After guiding procurement teams through dozens of extrusion equipment purchases, I have learned that a successful twin screw extruder wholesale deal rarely hinges on the lowest sticker price. It hinges on alignment: matching the machine's configuration to your material, your output target, and your total cost of ownership. The wholesale market is wide enough to accommodate almost any budget, from lab-scale units listing for a few hundred dollars to fully integrated compounding lines exceeding US $200,000 par ensemble (Liste des extrudeuses à double vis de laboratoire en plastique Accio en gros, 2026). That range is precisely why a disciplined sourcing process matters more than catalog browsing.

D'après mon expérience, the buyers who avoid costly mistakes are the ones who treat specifications as purchasing inputs rather than marketing copy. A 25mm lab unit with a 7.5kW motor and vacuum degassing solves a very different problem than a 100 kg/h, 80kW semi-automatic production extruder priced near Rs 15,00,000 par pièce (Nouvelles machines en plastique, 2024). Understanding your L/D ratio requirement, your screw diameter and output expectations in kg/h, et que vous ayez besoin de vis à engrenage co-rotatives pour le mélange ou d'une conception conique contra-rotative pour le granulage du PVC, une vague séance de shopping devient une décision défendable..

Le canal de vente en gros récompense également les acheteurs qui regardent au-delà de l'unité elle-même.. Que vous choisissiez un nouvel équipement auprès d'un fabricant vérifié d'extrudeuse à double vis, une machine remise à neuf provenant d'un marché secondaire approfondi qui répertorie des dizaines de milliers de produits d'occasion (Fabriqué en Chine.com, 2024), ou une version OEM/ODM configurée selon vos spécifications, les mêmes principes fondamentaux s'appliquent. Vet the supplier's business type, confirmer les certifications telles que CE et ISO9001, verrouiller les Incoterms et les étapes de paiement, et le budget pour le coût au débarquement du fret, devoirs, conversion de tension, et l'installation ajoute tranquillement. Fais ça, et le modèle de vente en gros devient un véritable avantage plutôt qu'un pari.

Point clé	Explication
Match configuration to material, not price	Co-rotating screws suit compounding and masterbatch making, while conical counter-rotating designs are built for soft and rigid PVC pelletizing with die-face cutting (JWELL Machinery, 2024). Buying on price alone risks the wrong screw and barrel geometry for your process.
Read specs as purchasing decisions	Diamètre de vis, L/D ratio, puissance du moteur en kW, and output in kg/h define throughput and quality. Wholesale lineups often name models by screw diameter with outputs from roughly 10 à 150 kg/heure (twinscrewgranulator.com, 2024), so translate each figure into your real production target.
Total landed cost beats unit price	Un États-Unis $25,000 used PVC pipe extruder (Fabriqué en Chine.com, 2024) can cost far more once freight, droits d'importation, voltage adaptation, and commissioning are added. Always model the full landed cost before comparing suppliers.

Conseils d'approvisionnement exploitables pour les acheteurs B2B

• Define your process envelope first. Document the polymer or formulation, target output in kg/h, and whether you need a compounding extruder, extrudeuse de recyclage du plastique, or pet food extruder before you request a single quote. This filters suppliers fast and prevents over- ou sous-dimensionnement.
• Verify the supplier's business type. Distinguish a manufacturer or factory from a trading company or group corporation, and confirm OEM/ODM capacity where relevant (Filtres de fournisseurs Made-in-China.com, 2024). A direct factory relationship usually means better pricing transparency and clearer accountability for the extruder gearbox, vis, and barrel.
• Demand certification evidence. Ask for current CE, ISO9001, and where applicable GMP or UL documentation rather than logos on a brochure. Certifications such as CE and ISO9001:2008 are standard across the category (Fabriqué en Chine.com, 2024), so missing paperwork is a red flag.
• Negotiate Incoterms and payment milestones explicitly. Tie payments to verifiable stages, such as deposit, pre-shipment inspection, et réception après mise en service, et confirmez si les devis sont EXW, GOUSSET, ou CIF. Cela vous protège sur une machine d'extrusion industrielle qui peut être expédiée pendant des semaines.
• Peser délibérément le neuf, l'occasion et l'OEM/ODM. Un marché secondaire profond couvrant des marques comme Berstorff, KraussMaffei, and Maris with outputs from 100 à 4,000 kg/heure (Euro-Machines, 2024) peut apporter une forte valeur ajoutée, mais seulement après avoir évalué l'usure de l'arbre, pièces de rechange disponibles, et durée de vie restante par rapport à une nouvelle construction.
• Inspectez avant d’accepter. Organiser un audit d'usine ou une inspection de contrôle qualité par un tiers couvrant l'alignement des arbres à couple élevé, état du bloc de pétrissage et de l'élément à vis, side feeder, pompe à fonte, changeur d'écran, et fonction de dégazage sous vide. Détecter un défaut au sol coûte beaucoup moins cher qu'après l'installation.

FAQ

Comment choisir un fournisseur en gros fiable d’extrudeuse à double vis?

D'après mon expérience, la fiabilité des fournisseurs se résume à vérifier le type d'entreprise avant toute autre chose. Made-in-China.com's search filters distinguish between manufacturer/factory, société commerciale, and group corporation, avec la capacité OEM/ODM (Filtres de recherche pour extrudeuse à double vis Made-in-China.com, 2024, lien). Je confirme toujours que je fais affaire avec une véritable usine plutôt qu'avec un revendeur., parce que cela détermine si je peux auditer la production, négocier directement les spécifications de la boîte de vitesses et des vis et barillets, et sécuriser les pièces de rechange plus tard. Ma courte liste de contrôle: demander la licence commerciale, demander une vidéo de l'étage de montage, obtenir des références d'acheteurs de ma région, et confirmer qu'ils peuvent fournir un granulateur à double vis ou une extrudeuse de mélange correspondant à mon application exacte plutôt qu'une unité générique du catalogue.

Quel est le compromis coût/qualité dans les extrudeuses en gros?

L'écart de prix ici est énorme, et c'est précisément pourquoi le compromis est important. Wholesale unit prices range from under US $2 per unit at scale to over US $200,000 par ensemble (Liste des extrudeuses à double vis de laboratoire en plastique Accio en gros, 2026, lien). A rock-bottom screw extruder price almost always signals compromises in the high-torque shaft, gearbox metallurgy, or barrel hardening — the components that fail first under continuous load. I treat the extruder motor power (kW) and L/D ratio as quality proxies: an underpowered motor or a short L/D suggests the manufacturer cut corners on the parts that drive throughput and melt quality. My rule is to spend on the gearbox and screw elements, because those determine the machine's service life, and never to chase the lowest quote without seeing third-party material certificates.

Should I buy new or used for my first wholesale order?

For a first wholesale order, I weigh the depth of the secondary market against my tolerance for risk. The used inventory is genuinely deep — Made-in-China.com alone lists over 74,746 Vente en gros de produits d'extrudeuse à double vis d'occasion (Made-in-China.com a utilisé une extrudeuse à double vis, 2024, lien), and used conical PVC pipe units are quoted around US $25,000 per set there. Euro-Machinery's catalog carries premium brands like Berstorff, KraussMaffei, and Maris with outputs from 100 kg/h à 4,000 kg/heure (Catégorie extrudeuses bivis Euro-Machinery, 2024). Used equipment from a reputable European source can deliver excellent value, but for a first order I usually lean new unless I can inspect the used machine in person or commission a professional condition report, because a worn intermeshing twin screw set is expensive to replace and hard to assess from photos.

How do I verify a manufacturer's certifications?

I never accept a certification claim at face value. The common certifications you will see listed include CE, ISO9001:2008, ISO9001, BPF, et UL (Taxonomie des certifications Made-in-China.com, 2024). My verification routine is to request the certificate document directly, note the certificate number and issuing body, then check that number against the issuing body's online registry. GMP matters specifically if I am buying a pharmaceutical or lab scale twin screw extruder, while CE is the baseline for European import. If a supplier cannot produce a scannable, traceable certificate, I treat the claim as unverified and move on.

What output rating do I actually need for my product?

This is where most buyers overspend or underbuy. Wholesale model lineups commonly use screw diameter as the naming convention, with output ranging from roughly 10 kg/h à 150 kg/heure (spécifications du produit twinscrewgranulator.com, 2024). I size the machine to my realistic production target plus a modest growth buffer, not the headline maximum. A lab scale twin screw extruder — say a 25 vis de mm avec un 7.5 kW motor delivering 50 kg/h with PLC and vacuum degassing (Liste des extrudeuses à double vis de laboratoire de gros Accio, 2026) — suits trials and small batches, while a 100 kg/h, 80 kW industrial unit (priced around Rs 15,00,000 per piece by New Plast Machinery, 2024) fits steady commercial runs. Buying far above your real extruder output (kg/heure) wastes capital and energy; buying below it forces overtime and premature wear.

What is the difference between conical and parallel twin screws?

The geometry dictates the application. A conical twin screw extruder uses screws that taper from a wider base to a narrower tip, which concentrates torque at the feed end and excels at heat-sensitive materials — it is the standard for soft and rigid PVC pelletizing with downstream die-face cutting and cooling (Ligne de granulation conique à double vis en PVC JWELL Machinery, 2024). Parallel screws maintain a constant screw diameter along their length, giving more flexibility for kneading block and screw element configurations, which makes them the workhorse for compounding, masterbatch making, and plastic recycling. In short, I reach for conical when processing PVC powder and parallel when I need a versatile compounding extruder with modular mixing zones.

Which extruder configuration is best for PVC pipe?

Pour PVC, Je précise presque à chaque fois une double vis conique contrarotative. La géométrie contrarotative assure un transport positif et doux, traitement à faible cisaillement dont le PVC rigide a besoin pour éviter la dégradation thermique, et le cône conique gère bien l'alimentation en poudre à faible densité apparente. Une ligne complète d'extrusion de tuyaux en PVC associe généralement cette extrudeuse à un dégazage sous vide pour éliminer les matières volatiles., un changeur d'écran, et les étapes d'étalonnage et de refroidissement en aval. La même plate-forme conique contrarotative est utilisée pour la granulation du PVC souple et rigide avec découpe à l'emporte-pièce. (JWELL Machinery, 2024), donc si j'effectue à la fois des travaux de canalisations et de granulés, cela me donne de la flexibilité sur une seule base de machine.

Quelles pièces de rechange dois-je commander avec la machine?

Acheter des pièces de rechange avec la machine est bien moins cher que de les acheter sous la pression des temps d'arrêt. My standard initial order covers a full set of wear-prone components: replacement screw elements and kneading blocks, a spare barrel liner or full screw-and-barrel set if budget allows, joints et garnitures, a screen changer breaker plate with screen packs, and key consumables for the side feeder and melt pump. I source these from a dedicated parts manufacturer so they match the original geometry — Screw And Barrel factory inventories these exact components (Extruder Machine Parts). I also confirm gearbox oil specification and order the first oil change supply up front, since that single step protects the most expensive subsystem on the machine.
