PVD Vacuum coating equipment has many sources of pollution


PVD Vacuum coating equipment has many sources of pollution, and its surface formation process is often the first pollution. Adsorption phenomena, drying and leaching processes, chemical reactions, mechanical treatments, and diffusion and segregation processes all increase various surface contaminants. The surface of the plated part before coating must be clean, otherwise the plated film will not have good adhesion. This is also true in the vacuum diffusion welding process. The strength of the welded joint is closely related to the surface cleaning treatment.

Since each manufacturer is different, the accessories used by manufacturers are also different, so the prices between manufacturers are also different. The equipment of vacuum coating equipment is basically the same, that is, in terms of hardware, the first thing you choose depends on whether the manufacturer you choose is highly qualified and has sufficient experience.

 

In fact, there are many factors that determine the price of vacuum coating equipment. Because the market is changing with each passing day, buyers must want both cheap and good. So last year's price and this year's price may be two concepts. When we buy, we should not blindly choose only the cheap ones, and we must purchase according to our own needs.


There are several types of vacuum coating equipment, depending on the process and equipment configuration, the evaporation coating machine is at 150 to 400 thousand, the multi-arc ion coating equipment is at 300 to 1.2 million, the magnetron sputtering coating equipment is at 600 to 1 million, and the tool coating equipment is at 700 to 1 million.
