Twin screw extruder screw elements are modular components installed on the screw shaft, responsible for conveying, melting, mixing, dispersing, and pressurizing materials inside the barrel.
Their performance directly affects product quality, output stability, and component service life.
At ZHITIAN, screw elements are engineered not only as replaceable parts, but as process-critical components developed based on real extrusion conditions.
ZHITIAN screw elements are manufactured using selected tool steels, PM-HIP materials, and corrosion-resistant alloys. Material choice is matched to abrasion level, fillers, and processing temperature, rather than relying on a single “universal” grade.
Strict control of spline geometry, pitch accuracy, and profile tolerance ensures high compatibility with mainstream twin screw extruders, including ZSK-type machines, without assembly stress or abnormal wear.
Conveying elements, kneading blocks, and mixing elements can be freely combined to support compounding, reactive extrusion, and granulation processes.
Balanced hardness and toughness help reduce chipping, adhesive wear, and fatigue damage under continuous high-torque operation.
Polymer compounding
Petrochemical and masterbatch granulation
Engineering plastics processing
Filled and reinforced materials
Color masterbatch production
Recycling and reprocessing lines
| Parameter | Description |
Outer Diameter | Customized according to extruder size |
Spline Type | Compatible with mainstream twin screw systems |
Element Types | Conveying, kneading, mixing, special profiles |
Material Options | Tool steel, PM-HIP alloys, corrosion-resistant alloys |
Surface Treatment | Nitriding or material-based wear resistance |
Manufacturing Standard | CNC machining + strict inspection |
The correct screw element selection depends on material abrasiveness, filler content, processing temperature, and required mixing intensity.
ZHITIAN provides technical support to help customers configure screw elements based on process objectives rather than catalog matching.
Wear-resistant screw elements use optimized alloy systems and controlled hardness distribution to withstand abrasive fillers and long production cycles, while standard elements are typically suited for low-wear applications.
They are widely used in plastics, petrochemical compounding, masterbatch production, recycling, and other continuous extrusion industries.
ZHITIAN specializes in the manufacturing of twin screw extruder screw elements, barrels, shafts, and gearboxes, with extensive experience in alloy material development and precision machining.
By focusing on material science, manufacturing control, and application feedback, ZHITIAN delivers screw elements designed for real-world extrusion reliability, not just nominal specifications.
