Components of Injection molding machine
For thermoplastics, the injection molding machine converts granular or pelleted raw plastic into final molded parts via a melt, injection, pack, and cool cycle. Atypical injection molding machine consists of the following major components:
A. The Injection System
The injection system consists of a hopper, a reciprocating screw and barrel assembly, and an injection nozzle. This system confines and transports the plastic as it progresses through the feeding, compressing, degassing, melting, injection, and packing stage.
