    Operating characteristics and selection method of vacuum coating machine

    Author: Qingzhou Tianbao machinery technology co.,ltd. Date: 2021-07-06 Click:

    The vacuum coating machine uses physical and chemical means to coat a layer of special performance coating on the solid surface, so that the solid surface has better performance than the material itself, so as to increase product quality, increase product life, save energy, and achieve better results. Economic benefits.

    The general working process of vacuum coating technology is as follows: Prime the product. In this way, small defects on the surface of the product can be covered, and the adhesion between the metal film and the product can be increased. Then vacuum coating, choose different metals to evaporate according to the different requirements of different products and customers, so as to achieve the metal effect on the surface of the product.



    Then the metal film is protected by ultraviolet spraying method to make the product meet some testing requirements. Some customers will also require halfway procedures after painting and before spraying, in order to achieve the purpose of increasing the color and achieving more appearance requirements. You can also adjust the surface gloss of the product, so that the surface effect changes from a mirror effect to a matte effect.

    The key points of vacuum coating machine procurement are as follows:

    1. The furnace body can be made of stainless steel, carbon steel or a combination of materials.

    2. According to the process requirements, different specifications and different types of coating equipment are selected, including resistance evaporation, electron beam evaporation, magnetron sputtering, magnetron reactive sputtering, ion plating, hollow cathode ion plating, multi-arc ion plating, etc.

    3. The fixture operation has rotating, rotating and rotating + rotating modes. Users can put forward corresponding requirements according to the size and shape of the substrate. Speed range and precision: ordinary adjustable and frequency conversion speed regulation.

    4. The vacuum system is composed of mechanical pumps, diffusion pumps, oil booster pumps, expansion pumps, Roots pumps, crucible wheel molecular pumps, etc. and supporting pneumatic, manual, and electric valves, pipelines, etc.

    5. The vacuum chamber body, the diffusion pump lack phase, lack of water, air pressure, electrical load overpressure, overcurrent and other abnormal situations with sound and light alarm.

    The above are the operating characteristics of the vacuum coating machine and how to choose. If you want to know other news, you can consult us, and we hope that our answers will be helpful to you.
