First: Is the cost of pvd coating machine coating very high?

Although the use of PVD coating technology can produce high-quality film layers, the cost of PVD coating process is not high. It is a very cost-effective surface treatment method, so PVD coating technology has developed very fast in recent years. PVD coating has become the development direction of surface treatment in the hardware industry. PVD is the abbreviation of English Physical Vapor Deposition (Physical Vapor Deposition), which refers to the use of low-voltage, high-current arc discharge technology under vacuum conditions, using gas discharge to evaporate the target and ionize the evaporated material and gas. Using the acceleration of the electric field, the evaporated substances and their reaction products are deposited on the workpiece. NCVM=Non-Conductive Vacuum Metallization: Literally translated as non-conductive vacuum plating (metal surfaceization), process: non-conductive coating. In fact, PVD is mainly said from the perspective of physical and chemical comparison, while NCVM focuses on the effect of coating. Expressed. In fact, the two are the same.

Second: May I ask which industries are the current pvd coating machine coating technology mainly used in?
The application of PVD coating technology is mainly divided into two categories: decorative coating and tool coating. The purpose of decorative plating is mainly to improve the appearance and decorative properties and color of the workpiece while making the workpiece more wear-resistant and corrosion-resistant to extend its service life; this aspect is mainly used in various fields of the hardware industry, such as door and window hardware, locks, bathroom 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; , drill bits, etc.) and other products.

Third: What is the thickness of the coating film of the pvd coating machine?
The thickness of the PVD coating layer is micron level, and the thickness is relatively thin, generally 0.1μm ~ 5μm, and the thickness of the decorative coating layer is generally 0.1μm ~ 1μm, so the surface of the workpiece can be improved without affecting the original size of the workpiece. Various physical properties and chemical properties can be maintained, and the size of the workpiece can be maintained basically unchanged, and no further processing is required after plating.

Fourth: What are the types of films that the pvd coating machine can coat?
PVD coating technology is an environmentally friendly surface treatment method that can truly obtain micron-scale coatings without pollution. It can prepare various single metal films (such as aluminum, titanium, zirconium, chromium, etc.), nitride films (TiN [titanium ], ZrN [Zirconium Gold], CrN, TiAlN) and carbide films (TiC, TiCN), and oxide films (such as TiO, etc.).

Sixth: What are the characteristics of the film deposited by the pvd coating machine coating technology?
The film plated 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 can greatly Improve the appearance and decoration performance of the workpiece.
