Description:

A plastic injection molding machine consists of several key components that work together to melt the plastic material, inject it into a mold, and then cool and eject the molded part. Here’s a breakdown of the major components and their functions:

Key Components of Injection Molding Machines:

  1. Injection Unit:

    • Function: This is responsible for melting and injecting the plastic material into the mold.
    • Components:
      • Hopper: A container that feeds plastic pellets into the machine.
      • Screw or Plunger: The screw (or sometimes a plunger in specific machines) rotates and pushes the plastic material through the barrel and into the mold. The screw also helps melt the plastic through friction and heat.
      • Barrel: A heated chamber that helps melt the plastic as it is being moved by the screw.
      • Nozzle: The point at which the molten plastic is injected into the mold cavity.
