What does the coating of the injection mold do to the mold?

With the development of injection mold processing technology, its structure becomes more and more complex, along with the emergence of new plastic materials, more and more plastic materials cause a lot of corrosion and wear on the mold. The solution is to choose a suitable coating to protect the injection mold. Enhance the flow of the plastic melt in the injection mold.

By applying multiple layers of coating to each location on the surface of the metal intermediate layer where the coating is needed, the surface of the injection mold that is cracked by corrosion can be protected by the coating so that the cracks do not continue to spread and corrode downward. In addition, the coating also prevents corrosion during the plastic injection molding process, such as corrosion caused by moisture in the particles.

Due to the special structure of the coating, the coating also has the advantage of greater coating density and adjustable micro-roughness. In addition, the coating is more resistant to oxidation and has a higher coating adhesion to solve corrosion, wear and adhesion problems on the surface of the injection mold.
