Advantages of 80/156 conical twin screw and barrel for wpc extrusion line:
1.Advanced Nitriding Technology
2.Anti-corrosion and Wear-resisting Duplex Metal SprayingTechnoloy
2.Anti-corrosion and Wear-resisting Duplex Metal SprayingTechnoloy
3. we uses special alloy powders beingsprayed and welded on the screw's ridge,and uses
different alloy and welding methods forthe screw of different functions.
Our counter rotating conical twin screw have followingfeatures :
- Conical twin screwmachined on CNC"WMW"Germany make thread milling machines by simulation software for betterperformance.
- Conical twin screwand barrel are specially designed for high calcium loading.
- compact&reliablegearbox
- designed for highoutput at low screw speed andless powerconsumption.
- Twopiece barrel construction for economical replacement can beprovided.
- Bi-metallic screw&barrel can be provided fortwo-three times more lifespan than nitridedscrew&barrel.
Features:
- Easyoperation
- Optimumperformance
- Durable
- Lowpower consumption
- Corrosion/wearresistance
