Vacuum coating machine coating technology is a new technology developed in recent years. Its principle is that the metal solid is heated and vaporized in a high vacuum state, and then deposited on the surface of the substrate in the form of molecules or atoms, thereby forming a thin metal film on the surface of the plated part. Since the metal is evenly distributed in the coating machine cavity after vaporization, the metal film formed on the surface of the plated part is usually very uniform.

      With the continuous improvement of people's living standards, people's requirements for the decoration of commodities are also getting higher and higher, which brings new challenges to the decoration of various commodities. Traditionally, the surface metallization of non-metallic objects or the surface decoration of metal objects are usually method of electroplating. However, due to the high toxicity and serious pollution of traditional electroplating, this technology has been gradually eliminated by the society today with the gradual strengthening of environmental protection awareness.
      Compared with the traditional electroplating method, the vacuum coating technology has the advantages of good decorative effect, strong metallic feeling, low cost (about 1/3 to 1/2 of traditional electroplating), less pollution, and easy operation. Especially in the application of non-metallic objects, it has incomparable advantages over traditional electroplating. In view of this, vacuum coating has been widely used in the surface metallization of various non-metallic products.
       Vacuum coating technology is the most widely used in plastic products. Plastic products are not beautiful, easy to age, poor mechanical properties, poor heat resistance, high water absorption, which restrict their expansion of application. Through vacuum coating technology, the surface of plastic is metallized, and organic materials and inorganic materials are combined, which greatly improves its performance. physical and chemical properties.

The advantages of vacuum coating machine coating products are mainly reflected in:
       1. Easy to clean, no vacuuming.
       2. Make the plastic surface conductive;
       3. Improve the appearance, the surface is smooth, the metallic luster is colored, and the decoration is greatly improved;
       Fourth, reduce the water absorption rate, the more times of coating, the fewer pinholes, the lower the water absorption rate, the product is not easy to deform, and the heat resistance is improved;
       5. Improve the surface hardness. The original plastic surface is softer than metal and is easily damaged. Through vacuum coating, the hardness and wear resistance are greatly increased;
       6. Improve weather resistance. Generally, plastics age quickly outdoors, mainly due to ultraviolet radiation. After aluminizing, aluminum has the strongest reflection of ultraviolet rays. Therefore, the weather resistance is greatly improved;
