Vacuum evaporation coating is to heat the material to be coated in a vacuum state, reach a certain temperature to evaporate it and enter the space in the form of molecules or atoms to achieve the purpose of coating. The vacuum coating is uniform and strong in adhesion, and the mechanical and chemical properties of the tool are improved. At the same time, the purity of the film is very high, the density is good, and the surface is bright, which greatly improves the output of the product.
