screw barrel for injection molding machines

Injection Molding Screw & Barrel

Screw and barrel are the most important components for Injection molding machines.
The Injection screw conveys, compresses, and melts resin pellets into a homogeneous state prior to injection. It often surfaced with hard cobalt- or nickel-based weldments or manufactured with tool steels that can be case-hardened or through-hardened.
The barrel is supporting the rotating and reciprocating screw and having consistent heat distribution across the entire barrel.
