Injection Moulding Screw Barrel

About Injection Moulding Screw Barrel

The Injection Moulding Screw Barrel is a critical component of an injection molding machine, responsible for conveying, melting, mixing, and injecting plastic material into molds with high precision. Designed to operate under high temperature and pressure conditions, the screw barrel ensures uniform plasticization, consistent melt quality, and efficient production of molded plastic components.

At Raj Industries, Injection Moulding Screw Barrels are manufactured using premium-grade alloy steel and advanced heat treatment technologies to provide excellent wear resistance, corrosion resistance, and long operational life. Our screw barrels are customized to suit various machine brands, processing materials, and production requirements.
