Advantages of Conical twin screw barrel for extruder:
1.Advanced Nitriding Technology
2.Anti-corrosion and Wear-resisting Duplex Alloy Spraying Technoloy
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.
REMARK:
· We are able to take mapping, design for clients and make products as per customer's drawing or sample excellently , also can help customer to repair the old screw and barrel by useing bimetallic-alloy process.
· Screw structure, compression ratio and material can be changed according to different products and output.
· Technological Process can be chosed acoodring to your requirments.
· Commonly used materials: 38crMoAIA, nitrogen treatment . Various high quality alloy steels , according to different usage, the choose for alloy is different, some require for abrasion-resistant while some require for corrsion resistant.
For standard, we have Fe-based, Ni-based, W2C alloy,Tunsten alloy etc for choice.
