High-Torque Twin Screw Extruder Barrel with Bimetallic Alloy Liner and Modular Construction for Plastic Compounding

This high-torque twin screw extruder barrel system is developed for plastic compounding, polymer blending, and chemical reaction extrusion processes that require strong mechanical support, stable processing conditions, and long operational life. It is suitable for high-load extrusion, intensive mixing, dispersion of fillers and fibers, reactive processing, and continuous chemical extrusion, covering applications such as engineering polymers, modified plastics, filled compounds, functional masterbatches, and specialty chemical products.

The barrel system adopts a robust modular construction and supports multiple liner solutions, including wear-resistant alloys, corrosion-resistant materials, bimetallic liners, and powder metallurgy-based composites, enabling reliable performance in environments with abrasive fillers, aggressive additives, and elevated temperatures. Through advanced metallurgical bonding methods, precision heat treatment, and CNC machining, the barrel achieves excellent concentricity, high structural strength, and consistent internal geometry.

An integrated multi-zone temperature control design, combining efficient heating elements and optimized cooling channels, ensures accurate thermal management throughout the extrusion process. This improves melt stability, reaction control, and overall product consistency. Compatible with co-rotating twin screw extruders, the barrel system can be fully customized in diameter range, processing section layout, liner material selection, and application-specific requirements, making it an effective solution for manufacturers seeking high-performance twin screw extruder barrels for plastic and chemical extrusion systems with high torque capacity, durability, and process flexibility.
