Product Introduction

Conical Twin Screw Barrel Set for PVC Pipes and Fittings

The conical twin screw barrel set is an essential component for PVC pipe extrusion, enabling manufacturers to produce high-quality pipes in an efficient and cost-effective manner.

The conical shape of the barrel set ensures that the material is mixed thoroughly, resulting in a smooth and uniform melt.

The screw configuration can be customized to suit the specific requirements of each PVC pipe extrusion process, ensuring optimal performance and efficiency.

It helps to increase the production output, resulting in higher profits. The extrusion process is also more efficient, with less energy being consumed to melt the PVC resin.

Additionally, the conical twin screw barrel set ensures that the resulting PVC pipe is of higher quality, with improved mechanical properties and a more consistent wall thickness.

Comparing to Single Screw Barrel, twin screw barrel is gradually adopted by many manufacturers because of its high efficiency, which has higher requirements for machining clearance. Our company has a professional team to help users solve design problems, and can also process according to the samples or drawings provided by customers.
