Advantages of twin screw pe pipe extruder line :
1.Advanced Nitriding Technology
2.Anti-corrosion and Wear-resisting Duplex Metal Spraying Technoloy
2.Anti-corrosion and Wear-resisting Duplex Metal Spraying Technoloy
3. we uses special alloy powders being sprayed and welded on the screw's ridge,and uses
different alloy and welding methods for the screw of different functions.
Our counter rotating conical twin screw have following features :
- Conical twin screw machined on CNC"WMW" Germany make thread milling machines by simulation software for better performance.
- Conical twin screw and barrel are specially designed for high calcium loading.
- compact&reliable gearbox
- designed for high output at low screw speed and less power consumption.
- Two piece barrel construction for economical replacement can be provided.
- Bi-metallic screw&barrel can be provided for two-three times more lifespan than nitrided screw&barrel.
Features:
- Easy operation
- Optimum performance
- Durable
- Low power consumption
- Corrosion/wear resistance
