The first, Is the cost of vacuum coating machine very high?

Although PVD coating technology can be used to coat high-quality films, the cost of PVD coating process is actually not high, and it is a very cost-effective surface treatment method. Therefore, PVD coating technology has developed rapidly in recent years. PVD coating has become the development direction of surface treatment in hardware industry. PVD is the abbreviation of Physical Vapor Deposition in English, which means that under vacuum condition, low voltage and high current arc discharge technology is adopted, gas discharge is used to evaporate the target and ionize the evaporated substance and gas, and the evaporated substance and its reaction products are deposited on the workpiece by the acceleration of electric field.NCVM = Non-conductive vacuum metallization: literally translated as non-conductive vacuum plating (metal surface plating), process: non-conductive coating. In fact, PVD is mainly said from the perspective of physical and chemical comparison, while NCVM focuses on the effect after coating. In fact, the two things are the same.

Second: What industries are the coating technology of vacuum coating machine mainly used in at present?

The application of PVD coating technology is mainly divided into two categories: decorative plating and tool plating. The purpose of decorative plating is mainly to improve the appearance and decoration performance and color of the workpiece, and at the same time make the workpiece more wear-resistant and corrosion-resistant and prolong its service life; This aspect is mainly used in various fields of hardware industry, such as door and window hardware, locks, sanitary hardware and other industries. The purpose of tool plating is mainly to improve the surface hardness and wear resistance of the workpiece, reduce the friction coefficient of the surface and improve the service life of the workpiece This aspect is mainly used in various products such as cutters, turning tools (such as turning tools, planing tools, milling cutters, drill bits, etc.).

Third: What is the thickness of the coating film of the vacuum coating machine?

The thickness of PVD coating film is micron, which is generally 0.1 μ m ~ 5 μ m, and the thickness of decorative coating film is generally 0.1μm~1μm, so it can improve various physical and chemical properties of the surface of the workpiece without affecting the original size of the workpiece, and keep the size of the workpiece basically unchanged.

Fourth: What kinds of films can be plated by the vacuum coating machine?

PVD coating technology is an environment-friendly surface treatment method which can truly obtain micron-scale coating and has no pollution. It can prepare various single metal films (such as aluminum, titanium, zirconium, chromium, etc.), nitride films (TiN[, ZrN〔, CrN, TiAlN), carbide films (TiC, TiCN) and oxide films (such as TiO, etc.).

Fifth: What are the characteristics of the film coated by vacuum coating machine ?

The film deposited by PVD coating technology has the characteristics of high hardness, high wear resistance (low friction coefficient), good corrosion resistance and chemical stability, and the life of the film is longer; At the same time, the film layer can greatly improve the appearance and decoration performance of the workpiece.
