The role of zinc alloy die casting electroplating mainly has the following aspects.

1. Improve the surface hardness and wear resistance: through electroplating, a layer of high hardness and strong wear resistance can be formed on the surface of zinc alloy die casting, which can effectively protect the surface of zinc alloy die casting from being worn or scratched.

2. Improve the corrosion resistance of the surface: zinc alloy die-casting parts may be affected by environmental factors such as oxidation and corrosion during long-term use, resulting in rust or corrosion on the surface. Through electroplating, a layer of anti-corrosion coating can be formed on the surface of zinc alloy die casting, which can effectively protect the surface of zinc alloy die casting from corrosion.

3. Beautify the surface: Through electroplating, a layer of bright, smooth, and beautiful coating can be formed on the surface of zinc alloy die casting, improving the appearance quality of zinc alloy die casting, and increasing its aesthetics and decoration.

4. Improve electrical and thermal conductivity: the surface of zinc alloy die-casting parts after electroplating can improve its electrical and thermal conductivity, which is conducive to the application of zinc alloy die-casting parts.

In summary, zinc alloy dies casting electroplating can improve the surface hardness, wear resistance, corrosion resistance, beauty and electrical conductivity, thermal conductivity, and other properties, can effectively improve the service life and appearance quality of zinc alloy die casting, is conducive to zinc alloy die casting in a variety of applications to get a better play.
