The plastic mold is a combined plastic mold used for compression molding, extrusion, injection, blow molding and low foam molding. Inject into the cavity of the plastic mold, then heat preservation, pressure retention, and cooling to form.

The process of making plastic molds is as follows:
1. During injection molding, the mold is clamped on the injection molding machine, and the molten plastic is injected into the molding cavity, and is cooled and shaped in the cavity.
2. The upper and lower molds are separated, and the product is ejected from the mold cavity and out of the mold through the ejection system.
3. The mold is closed again for the next injection, and the entire injection process is carried out in cycles.
