Choosing the Right Bimetallic Screw Barrel for Your PVC Applications

When sourcing a bimetallic screw barrel for high-filled PVC, several key factors must be considered to achieve your production objectives.

September 13, 2026

A high calcium carbonate screw barrel must withstand severe abrasion when processing PP or PE with high CaCO3 filler content.

Standard screw barrels may wear quickly, increasing the clearance between screw and barrel. This can lead to lower output, unstable melt pressure and poor plasticizing.

For high-filler production, wear-resistant bimetallic materials and suitable screw geometry can significantly extend service life.

If you need a replacement high calcium carbonate screw barrel, send us your screw diameter, L/D, CaCO3 percentage, required output and drawing. We can manufacture it according to your application.
