Injection Molding Machine

Plastic Injection
  • Injection molding is a manufacturing process for the fabrication of plastic parts.
  • A wide variety of products are manufactured using injection molding, which vary greatly in their size, complexity, and application.
  • The injection molding process requires the use of an injection molding machine, raw plastic material, and a mold.
  • Injection molding machines are typically characterized by the tonnage of the clamp force they provide.
  • All injection molding machines utilize a power source, injection unit, mold assembly, and clamping unit to perform the four stages of the process cycle.
  • The required clamp force is determined by the projected area of the parts in the mold and the pressure with which the material is injected.
  • Certain materials that require high injection pressures may require higher tonnage machines.
  • The size of the part must also comply with other machine specifications, such as shot capacity, clamp stroke, minimum mold thickness, and platen size.
  • Tonnage can vary from less than 5 tons to over 9,000 tons, with the higher figures used in comparatively few manufacturing operations.
Process
The plastic is melted in the injection molding machine and then injected into the mold, where it cools and solidifies into the final part. Injection molding machines consist of a material hopper, an injection ram or screw-type plunger, and a heating unit.

Process Cycle includes:
  • Clamping
  • Injection
  • Cooling
  • Ejection
