Description
Conical twin screws are core wear-resistant components for conical twin-screw extruders. Designed for processing PVC, WPC, TPE, TPU and other polymer materials, they realize stable plasticization, uniform mixing and continuous extrusion. Our products adopt advanced heat treatment and precision machining technology. Standard specifications are in stock, and customized dimensions can be produced based on customer drawings to match pipe, sheet and profile extrusion lines.
