Product Application
PVC pipe expander machine is used for belling plastic UPVC pipe. This machine can be used in the whole production line after the conical twin screw extruder and other auxiliary machines. The belling machine can bell pipe into two types: R-type and U-type pipe. It can be used for belling drainage and water pipes with all kinds of sizes. The whole process requires no manual operation.
Key advantage: Full automatic, stable and reliable, easy to operate — reduces labor costs and improves production consistency.
Technical Specifications
Belling types: R-type / U-type
Belling range: 50-630mm
Cooling: Strong wind or water
Calibration: Vacuum calibration inside mould
Product Features
R-Type & U-Type Belling
Suitable for both R-type and U-type plastic pipes — belling range 50-630mm.
Inline or Standalone Use
Can be used in line with pipe production line or operated alone — maximum flexibility.
Full Automatic Operation
Stable, reliable, and easy to operate — no manual intervention required.
Advanced Cooling & Calibration
Vacuum calibration inside mould + forced air/water cooling outside — ensures pipe shape stability.
Strong Cooling System
Uses strong wind or water to cool PVC pipe after shaping — the pipe shape will not transform easily, ensuring dimensional accuracy and quality.
Production Integration
Can be used in the whole production line after the conical twin screw extruder and other auxiliary machines — seamless integration for continuous pipe manufacturing.
