Advantages of Twin conical screw and barrel for extruder:
1.Advanced Nitriding Technology
2.Anti-corrosion and Wear-resisting Duplex Alloy Spraying Technoloy
3.We use special alloy powders being sprayed and welded on the screw's ridge,and use different alloy and welding methods for the screw of different functions.
Application:
Rubber,various high glass fiber, mineral fiber and PPA,PPS, PA6T, LCP,VO fire protection, ferrous power, magnetic powder and etc. Meanwhile,Used for PVC + 30% CaCo3, recylced plastic material,etc.
