China Conical Double Screw Barrel for PVC

For bimetallic screw ,we have adopted advanced technique(HP/HVOF)of surface harden Process by the whole screw surface,WPT1 alloy with corrosion resistant suits for nylon,PVC,PC,PMMA and so on.WPT2alloy corrosion resistant and high temperature resistant Suits for magnetic power ,maanetic powder,magnesium and alumimum powder.Bakelite injection and so on .WPT3 is compatible with WPT1 and WTPT2.
For bimetallic barrel ,we have raised the proportion of tungsten contained in alloy to 30%and 50%from previous10%,and we also have increasedthe processing length to 4000mm from the previous length of 3000mm.

Technical Parameters

The main advantage of screw barrel:
a. Advanced Nitriding Technology
b. Anti-corrosion and Wear-resisting Duplex metal Spraying Technoloy
c. 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.
