Rubber Extrusion Screw Barrel

Durable Screw and Barrel Solutions for Rubber Extrusion

Rubber extrusion places demanding requirements on screw and barrel performance. Rubber compounds can have high viscosity, strong friction, and different levels of filler loading, making stable conveying, controlled shear, and wear resistance essential.

PIPLL provides customized screw and barrel solutions for rubber extrusion equipment. Our solutions are designed to support reliable processing, stable output, and long service life for a wide range of rubber compounds and extrusion profiles.
