Vacuum coating of manufacturer's vacuum coating equipment
The vacuum coating equipment vacuum coating technology of vacuum coating machine manufacturers first appeared in the 1930s. Industrial applications began to appear in the 1940s and 50s. Industrial mass production began in the 1980s. It has been widely used in other industries. Vacuum coating refers to the deposition of a certain metal or metal compound on the surface of a material (usually a non-metallic material) in the form of a vapor phase in a vacuum environment, which is a physical vapor deposition process. Because the coating is often a metal film, it is also called vacuum metallization.
In a broad sense, vacuum coating also includes vacuum deposition of non-metallic functional films such as polymers on the surface of metal or non-metal materials. Among all the materials to be plated, plastic is the most common, followed by paper coating. Compared with metals, ceramics, wood and other materials, plastics have the advantages of abundant sources, easy control of performance, and convenient processing. Therefore, a wide variety of plastics or other polymer materials are used as engineering decorative structural materials and are widely used in automobiles, home appliances, and daily use. Packaging, craft decoration and other industrial fields. However, most plastic materials have defects such as low surface hardness, insufficient appearance, and low wear resistance. For example, a very thin metal film can be deposited on the plastic surface to give the plastic a bright metal appearance. It can greatly increase the wear resistance of the surface of the material, and greatly broaden the decoration and application scope of the plastic.
