PVD and CVD are the most commonly used surface treatment methods for tools and moulds, CVD is based on chemical vapour deposition and PVD is based on physical vapour deposition, as they differ in principle, the final coating results are different and each has its own focus in application.

Vacuum coating is a physical vapor deposition process (PVD) in which a metal or metal compound is deposited onto the surface of a material (usually a non-metallic material) in the form of a vapor phase under a vacuum environment. It is also called vacuum metallization because the coating is often a thin metal film. Vacuum coating in a broader sense also includes the vacuum vapor deposition of non-metallic functional films such as polymers on the surface of metallic or non-metallic materials. Read More

 During the PVD vacuum coating process, pressure fluctuations in the coater chamber can lead to uneven coating and poor repeatability. A mass flow controller controls the reaction gas and a pressure controller controls the pressure of the inert gas in the chamber to improve the final plasma vapour deposition (PVD) results.

Specialised physical vapour deposition (PVD) coatings are widely recognised for the key role they play in improving operational performance and extending the life of parts in manufacturing and industry. Read More

Vacuum coating machine in the process of daily use, must be irregular maintenance maintenance, only reasonable maintenance and maintenance, in order to make the vacuum coating machine work, higher efficiency, longer service life, the probability of emergencies is lower, so as to achieve the role of cost reduction.
