Product Description
A parallel twin screw extruder is widely used in plastic compounding, masterbatch production, polymer modification, and reactive extrusion. Featuring parallel co-rotating, intermeshing screws, it delivers efficient material conveying, uniform melt plasticization, and consistent dispersive and distributive mixing. This screw configuration also provides stable temperature control throughout the extrusion process, helping maintain product quality and process reliability.
The machine is suitable for processing a broad range of materials, including engineering plastics, filled polymers, color and additive masterbatches, recycled plastics, and wood-plastic composites (WPC). Its flexible screw design allows manufacturers to optimize mixing performance for different formulations and production requirements. As a result, parallel twin screw extruders are widely adopted in industries requiring high-quality compounding, pelletizing, and continuous extrusion with consistent output and efficient production.
Our parallel twin screw extruder features a modular co-rotating screw design that provides excellent dispersive and distributive mixing for a wide variety of polymer formulations. By selecting different screw element combinations, manufacturers can optimize material conveying, melting, mixing, and degassing based on specific production requirements.
The modular screw and barrel configuration allows the extrusion system to be adapted for multiple applications, including color masterbatch production, engineering plastic compounding, filled polymer processing, additive blending, and reactive extrusion, reducing equipment investment while improving production flexibility.
The extrusion system is equipped with a high-torque gearbox and optimized screw geometry to ensure stable material processing under high-load operating conditions. With a torque density of up to 12–15 Nm/cm³, the machine is capable of processing highly filled formulations containing up to 85% mineral fillers, while maintaining efficient melt mixing and stable extrusion performance.
Depending on the selected model, production capacities range from 50 kg/h to 5,000 kg/h, making the equipment suitable for laboratory development, pilot production, and large-scale industrial manufacturing.
The extruder adopts a multi-zone barrel heating system combined with liquid cooling and an advanced PID temperature control system to maintain stable processing conditions throughout the extrusion process. Temperature fluctuations are controlled within ±1°C, helping improve melt uniformity while reducing the risk of thermal degradation when processing heat-sensitive materials.
Integrated process monitoring and production data recording provide better process traceability and quality consistency, making the system suitable for applications that require stable manufacturing conditions, including engineering plastics, specialty compounds, and selected food-grade or pharmaceutical polymer materials.
To improve equipment durability, the parallel twin screw extruder is manufactured with bi-metallic wear-resistant barrels and hardened alloy screw elements, providing reliable performance when processing abrasive materials such as mineral-filled compounds, glass fiber-reinforced plastics, and engineering polymers.
Under normal operating and maintenance conditions, key wear components are designed for a service life exceeding 20,000 operating hours. The segmented barrel and modular screw construction also simplify maintenance by allowing individual components to be replaced without dismantling the complete extrusion system, helping reduce maintenance time and production downtime.
The Parallel Twin Screw Extruder is widely used for producing high-performance plastic compounds by blending base resins with fillers, reinforcing agents, and functional additives. Its efficient mixing capability ensures uniform material dispersion, making it suitable for manufacturing engineering plastics, glass fiber-reinforced compounds, flame-retardant materials, and mineral-filled polymers. These compounds are commonly used in the automotive, electrical, electronics, and industrial manufacturing sectors.
With precise temperature control and excellent dispersive mixing, the extruder is an ideal solution for manufacturing color masterbatches, black and white masterbatches, and functional additive masterbatches. It provides consistent pigment dispersion and additive distribution, helping improve the quality and processing performance of finished plastic products used in packaging, consumer goods, household appliances, and injection molding applications.
The high-torque transmission system enables the extruder to process highly filled polymer formulations containing up to 85% mineral fillers, as well as wood-plastic composite (WPC) materials. It is widely applied in the production of WPC decking, fencing, wall panels, outdoor flooring, PVC compounds, and calcium carbonate-filled plastics, where stable mixing and continuous production are essential for maintaining product quality.
The Parallel Twin Screw Extruder is also suitable for plastic recycling, polymer modification, and reactive extrusion. It can process recycled PE, PP, ABS, PS, and engineering plastics by incorporating stabilizers, compatibilizers, and performance-enhancing additives to improve material properties. This makes it an effective solution for manufacturers seeking to increase recycled material utilization while producing consistent, high-quality plastic pellets for reuse in various industrial applications.
