Carbide alloy screw barrel for plastic screw extruder

 

 

Techincal Advantages of  Bimetallic Nitrided treatment Paralllel twin screw barrel :

1.Advanced Nitriding Technology .2.Anti-corrosion and Wear-resisting Duplex Metal Spraying Technology.

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.What's more,we use

   the centrifugal casting technology of barrel for the excellent performance on wear-proof.

Especially 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
