How Do Semi-Automatic Blow Molding Machines Work?

The operation of a semi-automatic blow molding machine involves several steps:

  1. Preform Creation: The first step involves creating a preform or parison, which is a tube-shaped piece of plastic that will be heated and inflated.
  2. Heating: The preform is heated to a specific temperature to ensure it becomes pliable.
  3. Molding: The heated parison is placed in a mold. Air is then injected into the preform, causing it to expand and take the shape of the mold.
  4. Cooling: Once the product has taken shape, it is cooled to set the plastic.
  5. Unloading: Finally, the molded part is removed from the machine, and the process can begin again.
