Double alloy screw for Injection Molding Machine

Double alloy screw for Injection Molding Machine

Double alloy screw processing technology is mediumcarbon alloy steel forging，heat treatment，machining，and plasma surfacing Ni-alloy in screw flight.microstructure of screw steel is tempered sorbite, or martensite + carbides. These screws possess good strength and toughness, and high hardness. The screw can be widely used in PE，PC，PA，PS，PMMA，ABS，PVC，PSU，POM polymer material injection molding.
