Vacuum coating machine coating technology is widely used in plastic products. Plastics are often used in water cups, tableware, toys, decorations, etc. Plastics have the characteristics of easy molding, low cost, light weight, and no corrosion. Plastic products are widely used, but due to Its shortcomings restrict the expansion of applications. Through the application of vacuum coating technology, the surface of plastic is metallized, and organic materials and inorganic materials are combined, which greatly improves its physical and chemical properties. The advantages of vacuum coating technology are mainly reflected in the following aspects:

 1. Make the plastic surface conductive;
       2. Easy to clean, no vacuuming.
       3. Improve the appearance, the surface is smooth, the metallic luster is colored, and the decoration is greatly improved.
       4. Reduce the water absorption rate. After coating, the pinholes are reduced and the water absorption rate is reduced.
       5. Improve the surface hardness, the original plastic surface is softer than metal and more susceptible to damage. Through vacuum coating technology, the hardness and wear resistance are greatly increased.
       6. It can improve the weather resistance. Generally, plastics will age very quickly outdoors, mainly due to ultraviolet radiation. After aluminized, aluminum has the strongest reflection of ultraviolet rays, so the weather resistance is greatly improved.
       The coating technology of vacuum coating machine is applied in plastics, the advantages of plastics are more prominent, the application fields are also more extensive, and it is more favored by the people.
