Plastic molds need to be finely and intensively processed in the production process to ensure product quality and dimensional accuracy. In order to protect the plastic mold from scratches, corrosion and other damage, a protective film can be used for protection.

The protective film can be attached to the surface of the mold to avoid damage to the surface of the mold when the plastic flows. At the same time, the protective film can prevent plastic stains or oxidation from contacting the plastic mold, and protect the luster and appearance of the mold surface. This can prolong the service life of the plastic mold, reduce production costs and waste of time, and improve production efficiency.
