Vacuum silver plating domestic power supply and imported power supply price

Vacuum silver plating domestic power supply and imported power supply price

Vacuum power supply, the gap between domestic power supply and imported power supply is still relatively obvious, of course, the price is relatively favorable, a domestic 20KW intermediate frequency power supply is about 80,000, an imported intermediate frequency power supply is 200,000, the performance and reliability of imported power supply, The stability will be better. The domestic power supply may be better than the imported power supply in terms of service because the origin is in China.

Control system, many vacuum coating machines now use fully automatic control, but the difference in automatic control is still very large, most of them are still in semi-automatic state, which can truly realize fully automatic control, one-button operation coating equipment Not much, and functional modules vary greatly in automatic control to give adequate safety interlocks in operation.

Whether it is necessary to configure the low temperature trap PolyCold, the low temperature trap can be said to be a kind of icing on the cake, it can greatly improve the pumping speed, adsorb the condensable gas in the vacuum chamber on the cold coil, and purify the vacuum chamber. The atmosphere makes the film quality better. In the hot and humid summer, the use of low temperature traps undoubtedly improves the production efficiency to a great extent.

There are basically two types of vacuum pumping systems at present, one is a diffusion pump system, the other is a molecular pump system. The molecular pump system belongs to a clean pumping system. There is no oil return phenomenon of the diffusion pump, and the pumping speed is relatively stable and relatively Saving electricity and electricity expenses are a large part of the production and operation costs of coating enterprises. It is very important for the regular maintenance of the pump system, especially the regular replacement of the lubricating oil. Pay attention to the selection of the oil brand. The wrong choice can easily damage the vacuum pump.

At present, the vacuum detection system basically uses a combination of composite vacuum gauge, thermocouple gauge + ionization gauge. When this combination encounters a process of filling a large amount of gas containing C element, the ionization gauge is easily poisoned, causing damage to the ionization gauge. If For the process of plating gas containing a large amount of C element, it can be considered to configure a capacitor film gauge.
