The coating technology of vacuum coating machine is widely used in plastic products. Plastics are often used in water cups, tableware, toys, decorations and so on. Plastics are easy to form, low in cost, light in weight and non-corrosive. Plastic products are widely used, but their shortcomings restrict their wider application. Through the application of vacuum coating technology, the plastic surface is metallized and organic and inorganic materials are combined, which greatly improves its physical and chemical properties. The advantages of vacuum coating technology are mainly shown in the following aspects:

1. Make the plastic surface conductive;

2, easy to clean, no dust.

3. Improve the appearance, smooth surface, colorful metallic luster, and greatly improve the decoration.

4. Reduce the water absorption rate. After coating, the pinhole decreases and the water absorption rate decreases.

5. Improve the surface hardness. The original plastic surface is softer than metal and vulnerable to damage. Through vacuum coating technology, the hardness and wear resistance are greatly increased.

6. Weather resistance can be improved. Generally, plastics will age very quickly outdoors, mainly due to ultraviolet radiation. After aluminum plating, aluminum has the strongest reflection on ultraviolet rays, so the weather resistance is greatly improved.

The application of vacuum coating machine coating technology in plastics shows that the advantages of plastics are more prominent, the application fields are more extensive, and it is more popular with people.
