The vacuum coating of automatic vacuum coating equipment is a technology that produces thin film materials by physical methods. In the vacuum chamber, the atoms of the material are separated from the heating source and hit the surface of the object to be plated. This technology was first used to produce optical lenses, such as nautical telescope lenses, and later extended to other functional films, record aluminum plating, decorative coating and material surface modification, such as imitation gold plating on watch casings, mechanical knife coating, and changing processing Red hard. There are three forms of vacuum coating, namely evaporation coating, sputtering coating and ion plating.


The automatic vacuum coating machine prepares the film in vacuum, including the simple substance or compound film of crystalline metal, semiconductor, insulator, etc. Although chemical vapor deposition also uses vacuum methods such as reduced pressure, low pressure or plasma, vacuum coating generally refers to the use of physical methods to deposit thin films. There are three forms of vacuum coating, namely evaporation coating, sputtering coating and ion plating.


The functions of vacuum coating are multifaceted, which also determines that its application occasions are very rich. In general, the main functions of vacuum coating include imparting a high degree of metallic luster and mirror effect to the surface of the plated parts, making the film layer have excellent barrier properties on the film material, and providing excellent electromagnetic shielding and conductive effects.
