Vacuum sintering screw for Injection Molding Machine

Vacuum sintering screw for Injection Molding Machine

Vacuum sintering screw consist of high alloy steel core and surface NiCrBFe(Si), or NiCrBFe(Si)+WC, microstructure of screw steel core is pearlite or martensite,and screw surface is martensite or martensite+ WC. These screws possess excellent strength and toughness, high hardness, and excellent corrosion resistance, are suitable for halogen free and high glass fibre polymer material extrusion screw in severe wear and corrosion environment. The screw can be widely used in PE，PC，PA，PS，PMMA, ABS, PVC, PSU, POM, Al-plastics, plastics-wood polymer material injection molding.

Processing Technics:Heat treatment,Quenching, Nitriding treatment,Bimetallic alloy welding for screw,Bimetallic alloy centrifugal casting for barrel,Hard-chrome electroplating,

Excellent corrosion resistance, abrasion resistance and high working temperature

We can design the screw construction for you according to your finished products.
