Coating machines have been widely used in industries such as semiconductors, optoelectronics, healthcare, and aviation. In the field of chemical drugs, coating technology is used to ensure the purity and stability of materials; In the field of electronic optics, the manufacturing of high-precision components and devices cannot be separated from coating technology; In the fields of machinery and automotive manufacturing, coating technology is used for the treatment of metal surfaces; In the field of medical devices and food packaging, coating technology provides corrosion resistance and wear resistance.

Each type of coating machine has its specific working principle and application field. For example, a physical vapor coating machine utilizes energy such as electric arcs and high frequencies to evaporate or ionize metal and deposit it onto the substrate; The sputtering coating machine uses an arc beam, electron beam, or ion beam to peel off the metal target material and form a thin film.
