The principle of the vacuum coating machine is to evaporate the substrate and deposit it on the surface of the workpiece under vacuum conditions. As the evaporation of air molecules will cause resistance, it will make the film rough, so only in a high vacuum can the film become fine and bright. If the vacuum is not high, the film will lose its luster and the adhesion will also become worse. The early vacuum coating was based on the natural scattering of evaporation, with low combining rate and poor gloss. Now using an intermediate frequency magnetron sputtering target will accelerate the evaporation of molecular bombardment targets, deposited on the substrate.
Function of water chiller
The magnetron sputtering target can generate a very high temperature to deform the launch gun, so it has a water jacket cooling gun. The chiller is a water cooling device that provides constant temperature, constant current and constant pressure water cooling equipment. Its working principle is to inject a certain amount of water into the water tank, cool it through the cooling system, and then send the water to the equipment that needs to be cooled by the water pump. After the cooling water absorbs the heat, it flows back to the water tank to achieve the cooling effect. The cooling water temperature can be automatically adjusted according to need, and water can be saved for long term use. Cold water can control the temperature of the vacuum coating machine to ensure high quality of coating. If it is not equipped with a chiller, the vacuum coating machine will not be able to plate high precision film.
