Introduction to physical vapor deposition vacuum hot drilling decorative coating system
I. System overview and characteristics
Physical vapor deposition vacuum hot drilling decorative coating system is a set of efficient and accurate modern coating technology system. The system uses the principle of physical vapor deposition to decorate the hot drill material under vacuum environment, giving the hot drill material unique color, gloss and wear resistance. The system has the characteristics of simple operation, uniform coating, environmental pollution, etc., and can be widely used in jewelry, crafts, clothing and other industries.
2. Principle of physical vapor deposition
Physical vapor deposition is a technique that vaporizes the surface of a material source (solid or liquid) into gaseous atoms or molecules by physical methods, and deposits a thin film on the surface of a substrate. In the vacuum hot drilling decorative coating system, physical vapor deposition mainly uses electron beam or resistance heating to heat the coating material to the evaporation state, so that the evaporation particles directly shoot at the hot drilling matrix in the vacuum, and finally deposit a solid and beautiful film on the surface of the matrix.
