The medium frequency magnetron sputtering coating equipment has the advantages of fast sputtering rate and high deposition rate, which completely overcomes hitting the target arc and effectively controls the poisoning phenomenon. Alloy film, multilayer composite film, etc. can be plated on the surface of metal products and non-metal products. The product has beautiful coating, fine surface, wear-resistant and color-resistant characteristics, and can be plated in a variety of colors. At present, it has been widely used by well-known domestic OEM manufacturers. It is widely used in surface treatment and processing of mobile phone cases, computer accessories, magnesium alloy parts and high-end bathroom hardware.
