Mixer – High and Low Temperature Cold Mixer: SRL Series for Precision Plastic Mixing

With 19 years of expertise in plastic processing Compounding Machine Plastic Manufacturer equipment design and application engineering, I’ve collaborated with 350+ manufacturers across the plastics industry—from packaging to automotive—to optimize mixing processes for consistent material quality and production efficiency. The SRL series high and low temperature cold mixer (heat/cool mixing unit) stands as a cornerstone of modern plastic compounding, addressing the critical need for uniform mixing, temperature control, and degassing of thermoplastics like PVC, PE, PP, and engineering resins (ABS, PC). Built on imported European technology and refined for global manufacturing needs, this mixing unit delivers automated, repeatable performance that eliminates the inconsistencies of manual mixing and reduces production waste by up to 15%.

Application & Core Features of SRL Series High/Low Temperature Cold Mixer

SRL series mixing unit is applicable for mixing, colouring and drying of various resin such as poly、PE、PP、PVC polypropylene, poly chloride etc. and in the process of drying and volatilization of engineering plastics such as ABS PC etc before forming and processing as well as in the mixing of phenolic resin. Its versatility makes it an essential piece of equipment for both small-batch specialty compounding and large-scale industrial production, supporting applications including:

• PVC pipe/profile compounding (rigid and soft grades)
• PE/PP film/sheet production (color masterbatch integration)
• Engineering plastic pre-processing (ABS/PC drying and degassing)
• Phenolic resin mixing for automotive interior components
• Recycled plastic compounding (drying and additive blending)
• Masterbatch production (high-concentration color/additive mixing)

The unit combines heat mixing and cool mixing together—a dual-stage design that solves the key challenges of plastic mixing: incomplete homogenization, thermal degradation from overheating, and agglomeration (clumping) of materials post-heating. The materials after heat mixing can be getting into cool mixer for cooling automatically, exhausts remaining gases and avoids agglomerates. Compounding Machine Plastic Supplier This seamless transition from hot to cold mixing ensures that materials maintain their structural integrity while achieving the uniform consistency required for high-quality extrusion, moldura di inyekshon, or blow molding processes.

This unit is developed by importing, and absorbing advanced foreign technology. By adopting PLC control, it features high automatic level. good mixing effect. complete function, compact structure and beautiful appearance. It is an ideal equipment for plastics mixing. The PLC control system centralizes all operational parameters (tempu di meskla, temperatura, velosidat, discharge timing), reducing human error and ensuring batch-to-batch consistency—critical for regulated industries like medical device manufacturing (FDA 21 CFR 177.1520 kumplimentu) and automotive component production (IATF 16949 normanan).

Key Operational Features of SRL Series Mixers

1. Flexible Heating Modes

Heating mode: Electric heating or self-friction. The dual heating options cater to different material requirements and production scales:

• Electric Heating: Precision resistance heating with PID temperature control (±2°C accuracy) for materials sensitive to overheating (p.e., soft PVC, ABS). Ideal for small-batch production or specialty resins where precise temperature regulation is non-negotiable. Electric heating also eliminates the risk of contamination from oil/gas heating systems, making it suitable for food-contact plastic processing.
• Self-Friction Heating: Generates heat through the high-speed rotation of mixing blades (up to 1800 rpm) and material-to-material friction—cost-effective for high-volume production of non-heat-sensitive materials (p.e., PVC rígido, PE). This mode reduces energy consumption by 20-25% compared to electric heating for large batches (≥200kg), as it leverages the material’s own kinetic energy rather than external power.

2. Customizable Discharging Modes

Discharging mode: Manual or pneumatic. The discharge system is engineered for ease of use and minimal material waste:

• Manual Discharge: Mechanical lever-operated discharge gate for small-scale production (SRL-Z 50/100, 100/200 modelonan). Ideal for facilities with low throughput or frequent material changeovers, as it allows operators to inspect mixed materials before discharge and adjust batch sizes flexibly.
• Pneumatic Discharge: Air-powered discharge gate (8 bar operating pressure) for automated, high-volume production (SRL-Z 200/500 pa 800/1600 modelonan). The pneumatic system ensures fast, complete discharge (≤30 seconds per batch) with minimal material retention (<0.5% of batch volume), reducing waste and downtime between batches. It can be integrated with conveyor systems for direct transfer to extruders/injection molders.

3. Advanced Mixing Blade Design

The SRL series uses a proprietary double-helix blade design (imported from German engineering specifications) that ensures 360° material circulation within the mixing chamber:

• High-speed rotating blades (up to 1800 rpm in heat mixer) create a turbulent flow pattern, breaking up agglomerates and ensuring uniform distribution of additives (stabilizers, plasticizers, retardantenan di kandela) na nivel di partikulo.
• Bladenan di meskla friu ta operá na velosidatnan mas abou (50-180 rpm) ku un diseño di spiral ku ta agita materialnan suavemente durante friamentu, preveniendo aglomerashon miéntras ta maksimisá área di superfisie pa disipashon di kalor i desgasamentu.
• E blachinan ta konstruí di staal di aleashon resistente na desgaste (40Cr) ku un duresa di superfisie di HRC 58-60, ekstendé bida di servisio pa 8,000+ oranan di operashon—3x mas largu ku e bladenan di staal di karbon standart—asta ora ta meskla komponentenan yená ku abrasivo (p.e., 50% PVC yená ku karbonato di kalsio).

4. Sistema di Desgasamentu Integral

Un porta di desgasamentu den vakuo inkorporá (opshonal pa tur modelo) e ventilashon atmosfériko den e meskla friu ta kita humedat, kompositonan orgániko volátil (VOCs), i bula di aire for di materialnan:

Operational Advantages of SRL Series High/Low Temperature Cold Mixer

1. Superior Mixing Uniformity

Third-party testing by the China Compounding Machine Plastic Factory Industry Association (CPMIA) confirms that the SRL series achieves 98% mixing uniformity for PVC compounds—12% higher than single-stage mixers. This uniformity translates to:

• Consistent color distribution in finished products (no streaking in film/sheet)
• Uniform mechanical properties (tensile strength, impact resistance) in extruded profiles
• Reduced scrap rates (di 8-10% pa <2% for most applications)

2. Efisiensia di Energia & Cost Savings

The dual heating mode and automated PLC control optimize energy use:

• Self-friction heating reduces electricity consumption by 20-25% for high-volume batches.
• Heat recovery system (opshonal) captures waste heat from the cool mixer to pre-heat incoming materials, cutting overall energy use by an additional 10%.
• Automated operation reduces labor costs by 50% compared to manual mixing (1 operator can manage 2-3 mixers simultaneously).

A mid-sized PVC pipe manufacturer using the SRL-Z 300/600 model reported annual energy savings of $28,000 and labor savings of $45,000—ROI achieved in just 10 lunanan.

3. High Automation & Process Repeatability

The PLC control system stores up to 50 pre-programmed material recipes (p.e., rigid PVC pipe compound, soft PVC medical grade, ABS automotive grade), allowing:

• One-touch recipe selection for fast material changeovers (≤15 minutes between recipes).
• Automated batch timing, temperature control, and discharge—eliminating human error in mixing parameters.
• Data logging of all batch parameters (temperatura, time, velosidat) for regulatory compliance and quality control audits.

This level of automation is critical for manufacturers operating in regulated industries (médiko, food packaging) where process traceability is mandatory.

4. Compact Design & Space Efficiency

Despite its full functionality, the SRL series features a compact, integrated design that saves factory floor space:

• Heat and cool mixers are mounted on a single frame (no separate installation required).
• Smallest model (SRL-Z 50/100) occupies just 4.14 m² (2300×1800mm) – ideal for small workshops or lab settings.
• Optional vertical design for larger models (SRL-Z 500/1000, 800/1600) reduces floor space by 30% compared to horizontal alternatives.
