Co-rotating Twin Screw Extruder | High Torque Parallel Twin Screw Compounding Granulation Solution

A Co-rotating Twin Screw Extruder, also named Double Screw Extrusion Granulation Machine and standard Parallel Twin Screw Compounding Granulator, is the most mainstream core extrusion equipment for plastic modification, blending, filling and masterbatch production in global plastic industry. Our optimized High Torque Co-rotating Twin Screw Extruder upgrades transmission structure and screw torque design, delivering stronger mixing capacity, higher production stability and wider material adaptability than ordinary twin screw units, supporting diversified customized formula granulation for various modified plastic manufacturers, masterbatch factories and material research laboratories.

Target Application & Matching Specialized Model Classification

We develop targeted dedicated models corresponding to different modification demands, covering all your compounding production requirements:

Glass fiber reinforcement modification
Our PA/ABS/PC Glass Filled Twin Screw Pelletizing Machine and matched Twin Screw Extruder for Glass Fiber Reinforced Plastic are specially configured with screw elements for uniform glass fiber dispersion, preventing fiber breakage and agglomeration. They stably produce high-rigidity, high-strength glass-filled pellets for automotive parts, electronic housings and engineering plastic structural components.
High inorganic filling modification
The customized PP Calcium Carbonate Filled Twin Screw Granulator is designed for high loading talc powder, calcium carbonate, talcum and mineral filler filling. It solves poor feeding, powder overflow and uneven dispersion issues during high-filler production, widely applied for low-cost modified PP, injection molding filler materials and plastic film raw material production.
Masterbatch production line
Both Filler Masterbatch Twin Screw Pelletizing Machine and general-purpose Masterbatch Twin Screw Extruder adopt precise metering feeding, multi-stage vacuum devolatilization and efficient homogenization structure. They are suitable for black masterbatch, white masterbatch, color masterbatch and functional additive masterbatch continuous extrusion granulation, ensuring uniform pigment dispersion and stable color consistency of finished masterbatch pellets.
Polymer alloy blending & compatibilization
Our Polymer Blending Twin Screw Extrusion Machine realizes uniform melting, shearing and compatibilizing blending for incompatible polymer systems like PC/ABS, PP/PE, PA/PP alloy materials. It improves material toughness, weather resistance and comprehensive mechanical properties to meet high-end alloy plastic downstream application standards.
Laboratory small-scale research model
The compact Lab Twin Screw Extruder serves university laboratories, material R&D institutions and new material pilot test workshops. It features small occupied area, easy screw disassembly, adjustable process parameters and low trial raw material consumption, ideal for new formula trial production, formulation testing and small-batch sample preparation before mass production.

Core Advantages of Our High Torque Co-rotating Twin Screw Extruder

First, our whole series takes Parallel Twin Screw Compounding Granulator as basic structural design, adopting modular barrel and segmented combined screw configuration. Customers can freely adjust screw layout, length-diameter ratio and vacuum exhaust sections according to different formulas of filling, reinforcement, blending and devolatilization, realizing flexible switching between multiple production processes.

Second, the upgraded High Torque Co-rotating Twin Screw Extruder enhances gearbox load capacity and transmission stability, supporting long-term continuous high-load operation, increasing unit output while reducing energy consumption per kilogram of pellets. Multi-group vacuum exhaust channels effectively remove moisture, volatile monomers and residual small-molecule impurities, avoiding bubble, yellowing and poor surface defects of final plastic pellets.

Third, complete supporting auxiliary configurations are optional: side feeding device for adding powder/fiber, underwater pelletizing, water-ring cutting and strand pulling cutting systems, automatic batching feeding system, and online viscosity monitoring module. Whether you purchase a standalone Double Screw Extrusion Granulation Machine host or a full turnkey compounding pelletizing production line, we can complete customized layout design according to your factory site, hourly output target and formula characteristics.

For plastic modification enterprises, masterbatch manufacturers and new material R&D institutes, our series co-rotating twin screw extrusion equipment covers mass industrial production and laboratory small trial production scenarios. We provide pre-sales formula consultation, process scheme customization, overseas on-site installation & commissioning, operator technical training and 12-month whole machine warranty service, becoming your reliable long-term partner for plastic compounding and twin screw extrusion granulation projects.
