Intaa waxaa dheer, midabada leh cabbirka walxaha waaweyn ama agglomerates waa in la burburiyaa oo la miiriyaa (20-40 mesh) to improve dispersibility, iyo wasakhda (qaybo bir ah, siigada) waa in meesha laga saaraa si looga fogaado xidhashada qalabka extrusion iyo cilladaha masterbatch.

2.3.3 Xakamaynta Parameters Extrusion.
Twin-screw extrusion is the core step of TPE masterbatch processing, and the key parameters (heerkulka, xawaarihii xawaaruhu, cadaadiska extrusion, xawaaraha quudinta) must be precisely controlled to match the TPE type:
- – Xakamaynta heerkulka: The barrel is divided into 4-6 qaybaha xakamaynta heerkulka (qaybta quudinta, qaybta dhalaalidda, qaybta isku dhafka, qaybta isku midka ah, dhiman madaxa qaybta). The temperature of each section is adjusted according to the TPE processing temperature.

The temperature control precision should reach ±1℃ to avoid TPE degradation and pigment decomposition.
- – Xawaaraha isku dubaridka: The screw speed ranges from 200-800 rpm, adjusted based on TPE viscosity. High-viscosity TPEs (VAT, TPC) require higher screw speed (500-800 rpm) to generate sufficient shear force for pigment dispersion; low-viscosity TPEs (TPS) use moderate speed (300-500 rpm) to avoid material overflow.
- – Cadaadiska Soo Bixinta: The pressure ranges from 5-12MPa, kept stable (fluctuation ≤±0.5MPa) to ensure uniform mixing and shaping. High-viscosity TPEs require higher pressure, while low-viscosity TPEs use moderate pressure.
- – Feeding Speed: Adjusted to match the screw speed and extrusion speed, ensuring stable and uniform feeding. For high-viscosity TPEs, a forced feeding device is used to avoid material accumulation.
2.3.4 Post-Processing.
After extrusion, the strip-shaped masterbatch is cooled (water tank cooling, 20-30℃), granulated (particle size 2-5mm), screened (to remove unqualified particles), and packaged (sealed and moisture-proof packaging). For moisture-sensitive TPE masterbatch (TPU, TPA), the finished product is dried again before packaging to prevent moisture absorption.

4. Zhuoyue’s Full Series Extruders: Professional Solutions for TPE Masterbatch Processing
Zhuoyue has long been engaged in the research, development, and production of high-performance twin-screw extruders, and has accumulated rich experience in TPE masterbatch processing. Based on the unique processing characteristics of TPEs (viscosity sare, temperature sensitivity, moisture absorption) and the diverse needs of manufacturers (different TPE categories, production scales, application fields), Zhuoyue has launched a full series of extruders suitable for TPE masterbatch processing, oo ay ku jiraan HTS BASIC, HTS PLUS, HTS SUPER, ZTE, and HTE series. Each series has targeted performance advantages, providing personalized and efficient processing solutions for TPE masterbatch manufacturers of different scales.
4.1 Core Advantages of Zhuoyue’s Extruders for TPE Masterbatch Processing
Zhuoyue’s extruders are specially optimized for TPE masterbatch processing, with the following core advantages to meet the strict requirements of TPE processing:
4.1.1 Excellent Mixing and Dispersing Effect.
TPE masterbatch requires uniform dispersion of pigments and additives to avoid affecting the material’s elasticity and mechanical properties. All Zhuoyue’s twin-screw extruders adopt an intermeshing co-rotating structure, with a reasonable screw pitch, lead, and compression ratio design. The intermeshing and rotating of the twin screws generate strong shear force and kneading force, which can fully break pigment agglomerates and ensure uniform dispersion of pigments, sidayaal, and additives in the TPE matrix. The mixing uniformity reaches more than 95%, which is far higher than that of ordinary extruders.
Intaa waxaa dheer, the screws adopt a modular design, which can freely combine different screw elements (gudbinta, isku dhafka, xiirid) according to the TPE type. Tusaale ahaan, high-viscosity TPV/TPC masterbatch requires more mixing and shearing elements to enhance dispersion; low-viscosity TPS masterbatch uses more conveying elements to improve production efficiency.
4.1.2 Precise Temperature Control, Avoiding TPE Degradation.
TPEs are sensitive to temperature, and excessive temperature or temperature fluctuation can lead to material degradation (such as TPU hydrolysis, TPC chain scission). All Zhuoyue’s extruders adopt an advanced intelligent temperature control system, leh 4-6 independent temperature control sections, temperature control precision of ±1℃, and real-time temperature monitoring and alarm functions. The barrel adopts a double-layer jacket design, realizing rapid heating and cooling, and improving temperature response speed. The die head is equipped with an independent temperature control device, ensuring stable shaping of the masterbatch strip.
4.1.3 High Wear Resistance and Corrosion Resistance.
Some TPE masterbatches (such as TPA, TPC) contain high-hardness pigments or additives, which can wear the screw and barrel. Zhuoyue’s extruders use high-quality wear-resistant materials and advanced manufacturing technologies: HTS PLUS/SUPER/HTE series screws and barrels are made of imported wear-resistant alloy steel, undergoing bimetallic composite or laser cladding treatment, adkaanta dusha sare ≥65 HRC (HTS SUPER series ≥70 HRC), service life 2-3 times that of ordinary extruders; HTS BASIC/ZTE series screws and barrels are nitrided, surface hardness ≥60 HRC, meeting the needs of ordinary TPE masterbatch processing.
4.1.4 Vacuum Exhaust and Moisture Removal Capabilities.
TPEs such as TPU and TPA have high water absorption, and moisture can cause bubbles and defects in the masterbatch. All Zhuoyue’s mid-to-high-end extruders (HTS PLUS/SUPER/HTE) are equipped with a vacuum exhaust device, which can effectively remove moisture, volatile substances, and air in the material, ensuring the density and quality of the masterbatch. The vacuum degree is adjustable (0.06-0.09MPa), adapting to different moisture content requirements.
4.1.5 High Production Efficiency and Energy Saving.
Zhuoyue’s extruders adopt high-torque gearboxes and optimized screw structures, with strong conveying capacity and high production efficiency. Compared with ordinary extruders, production efficiency is increased by 20%-50%, and energy consumption is reduced by 15%-25%. Tusaale ahaan, HTS SUPER series production capacity reaches 1000-3000kg/h, suitable for large-scale mass production; ZTE series production capacity is 50-400kg/h, suitable for small-batch production.
4.1.6 Intelligent Control and Easy Operation.
All extruders adopt a PLC intelligent control system and touch screen operation interface, which can store up to 100 sets of formula and processing parameters. When switching between different TPE masterbatches, only the corresponding parameters need to be called, avoiding repeated debugging. The HTS SUPER series is equipped with cloud control functions, realizing remote parameter adjustment, la socodka xogta wax soo saarka, iyo dayactirka saadaalinta, xaqiijinta maamulka wax soo saarka garaadka.
