Twin Screw Extruder Screw Elements | Eco-Friendly Wear-Resistant Co-Rotating Segments
Our co-rotating twin screw extruder screw elements are the core modular spare parts of parallel twin screw compounding equipment, widely recognized as the heart of plastic extrusion lines. Adopting self-wiping intermeshing geometry, these twin screw segments realize full-process material conveying, melting, dispersive mixing, distributive kneading, pressure building and devolatilization in the extruder barrel.
All screw elements adopt 5-axis full CNC precision machining, strictly follow standard involute spline parameters, and perfectly match mainstream co-rotating twin screw extruder models including JSW TEX, Leistritz ZSE, Berstorff, APV and lab small extruders. We supply complete series standard and custom screw segments, covering conveying elements, kneading blocks, slotted mixing elements, reverse anti-backflow L-type segments and special transition parts, fully meeting diverse compounding formulas for eco-friendly new materials, engineering plastics, masterbatch and food extrusion.
With multiple wear & corrosion resistant alloy material options and stable HRC58–62 hardness after vacuum heat treatment, our co-rotating twin screw extruder screw elements feature outstanding machinability, long service life and no material carbonization during continuous production.
Standard forward conveying blocks (single-flight D-type, two-flight SK series, multi-lead large throughput segments), deep-groove feeding elements, reverse L-type anti-backflow screw segments. Different lead & length ratios adjust material delivery speed and compression ratio, suitable for high-volume stable feeding, venting and pressure holding sections.
Full-angle standard kneading blocks for co-rotating TSE: KB30°, KB45°, KB60°, KB90°. Adjustable shear intensity from gentle low-shear mixing to intense high dispersion mixing, ideal for uniform blending of fillers, glass fiber, color masterbatch and biodegradable polymer raw materials.
SME slotted two-flight mixing elements, ZME reverse single-head mixing blocks, TME multi-distribution segments, NSF transition parts. Optimized flow channel design eliminates material dead zones, improves self-cleaning performance and reduces material degradation for low-carbon eco extrusion production.
