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.

PVD coating is a common tool coating used in industrial production and has been developed for a long time, and is widely used in cutting tools, tooling and other finishing industries. However, as the level of industrial production increases, the requirements for tool coatings are becoming higher and higher. Although the preparation methods are progressing, it is inevitable that there will still be some shortcomings in the preparation process. Read More

The specific principle of PVD (ion coating) technology is the use of low voltage, high current arc discharge technology under vacuum conditions, the use of gas discharge to evaporate the target material and make the evaporated material and gas are ionised, the use of electric field acceleration, so that the evaporated material and its reaction products deposited on the workpiece.

The production conditions of die casting moulds are the most demanding, with metal solutions at high temperatures of 600-800°C, injection through high pressures and constant thermal expansion and contraction of the mould surface, resulting in a very short service life for die casting moulds, which constantly require mould repair and maintenance during production. The main causes of die casting mould failure are cracking, erosion, sticky material and deformation. Read More

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.

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.
