PVC Plastic Extruder Machine Bimetallic Conical Double Barrel And Screw
1 . Description
The bimetallic barrel for single screw is a kind of barrel moulding 2-5mm thick alloy coat on the barrel inner wall which has excellent corrosion resistance, abrasion resistance and high working temperature.And its useful service life is greatly improved contrast to the common nitrided barrel.Bimetal has more obvious advantage when processing special plastics to enhance the abrasion life, such as engineering plastics, flourine plastics,PPO,and etc.
The company uses special alloy powders being sprayed and welded on the screw's ridge, and used different alloys and welding methods for the screw of different functions.
