An automatic plastic injection molding machine is a high-speed industrial system that melts polymer granules and injects them into a mold to manufacture identical plastic parts with no human help. It uses PLC controls, a hydraulic or servo clamping unit, and a heated injection barrel.
Main Parts
Hopper: Holds raw plastic pellets and feeds them into the barrel.Injection Screw: Melts and pushes the liquid plastic forward.
Clamping Unit: Holds and locks the mold tightly shut under high tonnage pressure.
PLC Controller: Manages cycle times, temperatures, and automated triggers.
Ejector Pins: Push the final cooled part out of the open mold.
