In the precision mold industry, molds are often subjected to high pressure, high temperatures, and repetitive friction, especially in processes such as plastic injection molding, die casting, and stamping. As a result, mold surfaces are prone to issues such as wear, galling, corrosion, and fatigue cracking. With increasingly stringent product dimensional tolerances and longer service life requirements, hard coating technologies have gradually become a crucial method to extend mold life and improve molding quality.Dah Young offers a range of specialized coating solutions tailored to mold usage conditions, such as TiN, CrN, TiAlN, and DLC coatings.

These coatings effectively enhance mold surface hardness, corrosion resistance, and release properties, while reducing friction coefficients and surface adhesion. For different materials and working conditions (such as aluminum alloy die casting, high-hardness cold work molds, and plastic mirror-finish molds), Dah Young also provides coating-related technical support, helping customers extend mold life while maintaining high-precision product quality and production stability.
