High-Performance Material Twin Screw Extruder Screw Elements with Precision Splined Bore and Modular Screw Design

This is a core conveying and mixing component for twin-screw extruders, widely used in plastic compounding, polymer processing, new energy materials, and chemical industries. It is designed to precisely transport, shear, and blend materials under high-temperature, high-torque conditions.

• Precision Splined Bore: The internal spline design ensures a secure, high-torque connection with the extruder shaft, enabling reliable power transmission even under heavy loads.
• High-Performance Material: Manufactured from premium high-speed tool steel (e.g., 6542, W6Mo5Cr4V2) or nickel-based alloys, with heat treatment to achieve exceptional hardness, wear resistance, and corrosion resistance for long service life.
• Modular Screw Design: As part of a modular system, these elements can be freely combined with different lead lengths and pitch profiles to achieve customized conveying, shearing, mixing, and venting processes.
• Precision Machining & Surface Finish: The spiral surfaces are precision-machined and polished to minimize material adhesion, ensuring continuous, stable extrusion performance.

• Plastic modification, masterbatch production, and engineering plastic compounding
• Biodegradable and compostable plastic processing
• New energy materials (e.g., lithium battery anode/cathode materials) mixing
• Specialized chemical powder and filler masterbatch extrusion

• convey screw segment
• mixing screw segment
• kneading block&disk
• transition screw element
• deep groove transfer element
