A PVC pipe extruder screw barrel directly affects plasticizing quality, output and production stability. PVC is heat-sensitive, so the screw design must provide efficient mixing without excessive shear or melt temperature.
For PVC pipe extrusion, parallel twin screw and conical twin screw barrels are widely used. Screw geometry should match the PVC formulation, CaCO3 content, machine model and required output.
If your extruder has lower output, unstable plasticizing or excessive screw wear, replacement may improve production performance.
