Silicone Extrusion Screw Barrel

Precision Screw and Barrel Solutions for Silicone Extrusion

Silicone extrusion requires stable feeding, gentle plasticization, accurate temperature control, and clean material handling. Whether producing silicone tubes, profiles, foam products, or medical-grade components, the screw and barrel system directly affects surface finish, dimensional consistency, output stability, and material waste.

PIPLL provides customized screw and barrel solutions for silicone rubber extrusion equipment. Each solution is designed according to the silicone compound, extruder model, product profile, output target, and curing process.
