Equipment application


Plastic has the characteristics of light weight, excellent performance, easy molding, easy processing and so on. It has a wide range of applications. It is an indispensable material in daily life and national economy. However, it has some disadvantages such as lack of metallic luster, low surface hardness and easy aging. In order to overcome the shortcomings and improve the additional functions of plastics and further expand the use of plastics, it is necessary to treat the surface of plastics. The coated plastic products have strong metallicity, high brightness and little environmental pollution in the production process.

The application of vacuum coating technology in plastics, resins and other industries has greatly expanded its use in various fields. Through PVD, plastic products can show good metal texture, improve the appearance and decoration of plastic products. At the same time, due to the metallization effect, its electrical, thermal and corrosion resistance properties are also greatly improved, and the mechanical strength of its surface is improved 。 After the surface of plastic products is vacuum coated with a certain metal film, it will have the color of the metal, thus playing a surface decoration function, such as aluminum, chromium, brass, stainless steel, etc. have different colors. Using plastic instead of metal to produce some parts with complex shapes can save a lot of working procedures, improve work efficiency and save a lot of metal materials. If the coating layer is aluminum, it can also be colored by coating or other methods to obtain various colors, and the decoration effect is very good.

Generally, the process of vacuum coating on plastic and other products is: surface cleaning → electrostatic removal → primer spraying → primer baking → vacuum coating → topcoat baking → topcoat baking → packaging.
