In daily life, the application of coating technology is everywhere, such as bathroom, furniture, electronic products, packaging materials, decoration fields, etc., which can not be separated from the coating technology of vacuum coating machine. The application fields are different, the required effects are different, and the coating technology used is also different. The most commonly used coating technologies are evaporation coating, ion coating and magnetron sputtering coating. So what are the differences and advantages of these coating technologies?

Evaporation coating technology can be resistance evaporation, electron beam evaporation, induction evaporation, etc. In general decoration field, there are many evaporation vacuum coating machines, so the technology applied by ordinary evaporation coating machines is naturally resistance evaporation technology. In daily life, some objects don't have high requirements on the surface film structure and adhesion, and the melting point of the film material to be plated is relatively low, so everyone generally chooses evaporation coating because the evaporation coating machine has the advantages of simple coating technology, low equipment investment cost and high efficiency. Generally, electron beam evaporation coating technology is adopted, which is almost always used in the optical field, because electron beam evaporation coating technology has the advantages of high speed, high efficiency, wide application fields, but high cost. Therefore, there are many applied optical fields.

Ion plating technology includes evaporation ion plating and sputtering ion plating. It can also be divided into multi-arc ion plating, cathodic ion plating and so on. The application of these coating technologies is also determined according to the advantages of the coating technology itself, the material characteristics of the substrate to be plated and what film layer to be plated. Ion plating with vacuum coating machine is widely used in decoration fields, such as bathroom, watch, clock, mechanical parts, car lamps and other fields.

The coating technology of magnetron sputtering vacuum coating machine is divided into DC magnetron sputtering coating technology, medium frequency magnetron sputtering coating technology and radio frequency magnetron sputtering coater. These three coating technologies are also determined according to the required substrate materials and what target materials need to be plated. For example, if pure metal is plated, DC magnetron sputtering coating machine is generally selected. Compound film coating, generally choose medium frequency magnetron sputtering coating technology; If the insulating film is coated, there will be more radio frequency sputtering coating technology.
