Evaporation coating machine is used to coat aluminum on plastic surface

Evaporative vacuum coating machine is a special equipment for evaporating aluminum plating on plastic surface. It has fast film forming rate, strong film layer, bright color, and the film layer is not easily polluted. The electroplating equipment can obtain good compactness, high purity and uniform film thickness. The film layer does not produce waste liquid or waste water, which can avoid environmental pollution. It is an ideal equipment for large-scale production. The equipment is widely used, mainly in industries such as automotive reflective nets, handicrafts, jewelry, shoes and hats, watches, lamps, and decorations. It is mainly composed of four parts: vacuum chamber, exhaust system, evaporation system and electrical equipment.

The preparation of the film by the vacuum coating machine can prevent the contamination of the film material and the surface of the plated parts, eliminate the space collision, improve the compactness of the coating, and can prepare a single compound coating with special functions. In order to improve the uniformity of the coating thickness of the vacuum coating machine, a planetary mechanism or a rotating device is clamped in the vacuum chamber of the vacuum coating equipment, such as a planetary motion mode, the film uniformity of the motion mode is good, and the step coverage of the vacuum coating equipment coating The vacuum coating chamber with good performance, large carrying capacity and full use of effective space is a common mode of movement. The exhaust system is generally composed of mechanical pumps, diffusion pumps, pipes and valves. In order to increase the flow rate of the pump, a mechanical pump and a diffusion pump between the superchargers can be added. Therefore, not only the exhaust system with low pressure in a relatively short period of time to ensure a fast working cycle, but also the need to ensure that the vapor source of gas and the surface of the vapor-deposited workpiece are quickly removed. The evaporation system of the vacuum coating equipment includes electrical equipment and a heating evaporation source. The electrical equipment includes measuring the thickness of the vacuum film and a console.
