Customed gas pipe conic gear components and parts
45/90, 51/105, 55/110, 65/132, 72/152,80/156, 80/172, 92/188.
Advantages of65/132 conical twin screw and barrel for wpc extrusion line :
1.Advanced Nitriding Technology
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 onCNC"WMW" Germanymake thread milling machines by simulation software for betterperformance.
- Conical twin screw and barrel arespecially designed for high calcium loading.
- compact&reliable gearbox
- designed for high output at low screwspeed and less power consumption.
- Two piece barrel construction foreconomical replacement can be provided.
- Bi-metallic screw&barrel canbe provided for two-three times more lifespanthan nitrided screw&barrel.
