Mold coatings refer to a special treatment applied to the mold surface, creating a protective layer that enhances hardness, wear resistance, and corrosion resistance. Additionally, they can withstand the degradation caused by high temperatures, high pressures, and chemical substances such as acids and bases.

The primary purpose of the coating is to protect the mold surface from oxidation, corrosion, and wear. Without the protective coating, the mold surface is prone to damage, leading to a shorter mold lifespan and higher costs.

Mold coatings can also improve the coefficient of friction of molds, making the molding process smoother and more efficient, thereby enhancing the production efficiency and quality of the molds.
