Are you still worried about choosing a suitable vacuum coating equipment?
First of all, we need to know the definition of vacuum coating machine, which mainly refers to the use of some equipment that needs to be carried out under a high degree of vacuum. So what types of vacuum coating equipment are there? It includes many types including PLD laser sputter deposition, magnetron sputtering, and vacuum ion evaporation. The main idea of the researchers' design of vacuum coating equipment is to divide it into two types: evaporation and sputtering. The principle of this product is also quite simple, that is, the material on the surface is completely evaporated in different forms of atomic groups and ions by heating the surface material, and finally all settles to the surface of the substrate to form a thin film through the film-forming process.
The beginning of vacuum coating equipment is a long time ago. The original vacuum coating technology first appeared in the 1930s, and it was applied in industrial applications more than ten years later. The time when vacuum coating equipment was widely used was in the 1980s. The method used by the vacuum coating equipment belongs to a kind of physical vapor deposition process. Because the metal film is often used for its coating, it is also called vacuum metallization. It also has a broader meaning, that is, the surface vacuum evaporation of metal or non-metal materials produces many films with non-metal functions such as polymers. Among all the plated materials of vacuum coating equipment, in the long-term development, plastic is now the most common material, followed by paper. Compared with metal, wood and metal, its cost is cheaper and more economical. The performance is also easier to be regulated, the processing is very convenient, and the variety is easy to choose, so it is widely used in the automotive packaging industry. However, as a vacuum coating equipment, plastic is not the only one, because its hardness is not enough, its appearance is not beautiful, its wear resistance is low, and its service life is short. Therefore, many manufacturers will coat the surface of the plastic with a layer of hard and beautiful metal to improve its performance.
