PPR Extrusion Screw Barrel

High-Performance Screw Barrel Solutions for PPR Pipe Extrusion

PPR pipe extrusion requires consistent melt quality, stable pressure, efficient plasticization, and reliable long-term operation. The screw and barrel are key components that influence pipe surface quality, wall-thickness consistency, output efficiency, and energy consumption.

PIPLL provides customized screw and barrel solutions for PPR pipe extrusion lines. Our systems are engineered according to the extruder model, pipe diameter, material grade, output target, and production conditions.
