1. Color diversity: PVD (Physical Vapor Deposition) technology can produce a variety of color coatings to meet the needs of different users.

2. Wear and corrosion resistance: PVD coating has high hardness and wear resistance, which can resist scratches and wear in daily use, and also has good corrosion resistance.

3. Improving product quality: PVD technology can produce various single metal films, nitride films, carbide films, as well as oxide films, achieving diverse colors and textures.

4. Environmental friendliness: Compared with traditional processes, PVD technology does not produce toxic or harmful substances during the production process, making it more environmentally friendly.
