Dedicated 80/156 conical twin-screw barrel for PVC modification and granulation

This JCD 65/132 bimetallic conical twin screw barrel is specially designed for high-torque extrusion and high calcium PVC processing. It is widely used in high-fill PVC profile, pipe, wall panel and decorative extrusion production lines with calcium powder filling.

Adopting SACM645 alloy base with high-density bimetallic alloy layer, it has stronger wear resistance and torque bearing capacity than ordinary nitrided screw barrels. It ensures stable plasticizing and smooth extrusion even under long-term high-load operation, greatly extending service life when processing highly abrasive materials.

Q: Why use bimetallic for high calcium PVC?

A: Bimetallic structure provides much higher wear resistance, effectively resisting abrasion from calcium powder and extending service life by 2–3 times compared with standard nitrided barrels.

Q: Is this 65/132 barrel suitable for high-torque extruders?

A: Yes. It is reinforced for high-torque working conditions, with stable structure and no deformation during long-term heavy-duty extrusion.

Q: Can it be customized to my extruder?

A: Yes. We can customize installation size, length and structure according to your extruder drawings.

With precision machining and bimetallic alloy technology, JCD 65/132 conical twin screw barrel solves the problems of fast wear, poor plasticizing and unstable output in high calcium PVC extrusion. It is the ideal matching part for high-torque, high-fill extrusion production lines.
