- surface coating of automotive casings
There are generally two types of coating technologies widely used in the automotive industry, the first being PVD (Physical Vapor Deposition) technology. It refers to the use of arc (low voltage and high current) discharge technology in vacuum, which uses gas discharge to evaporate the target material, and ionize both the evaporated substance and gas. Under the action of an electric field, the evaporated substance and its reaction products will deposit on the workpiece. The technique of depositing a thin film with a certain special function on the surface of a substrate.If you want to deposit a thin film on the surface of the substrate, it is necessary to create a good vacuum environment. Therefore, we need to choose suitable and high-quality vacuum pumps and filters.
The second one is PMC. It is an environmentally friendly surface treatment method that can achieve coatings at the micrometer or even nanometer level. The technology is used for surface coating of various materials for automotive interior and exterior decoration. As it can adjust the color of the film layer, it is often used to generate colorful film layers, and the overall visual effect is very gorgeous. PMC is also applied in the lamination technology of various metal material coatings and the layering of ceramic compound materials.
The above two technologies are common vacuum coating technologies in the automotive industry. Vacuum coating technology is applied in many industries. Besides decorative purposes, according to different film performance, it can achieve different effects such as salt spray resistance, scratch resistance, corrosion resistance, anti-static, fingerprint resistance, conductive and thermal conductivity, etc.
LVGE has been engaged in the vacuum filtration for over 10 years. We has served many vacuum coating applications and also collaborated with well-known automotive manufacturers. We believe that our rich case studies can support us in recommending or designing suitable filters for you!
