Key Capabilities
- PVC and PU pellets can be processed into variable-diameter or straight tubing at line speeds of approximately 10–50 m/min.
- The screw and barrel use 38CrMoAlA nitrided steel, while the extrusion head and die are made from corrosion-resistant S136 mold steel with a mirror finish.
- Temperature is controlled within ±1°C during extrusion.
- Servo closed-loop control regulates each change in tubing diameter. A specially designed flow path inside the extrusion head guides the molten material gradually from one diameter to another, while stable melt pressure and temperature keep the tapered transition smooth and free of defects.
