pvd coating machine, that is, physical vapor deposition coating machine, according to its working principle and technical characteristics, can be divided into the following categories:
First, vacuum evaporation coating machine
Vacuum evaporation coating machine is a kind of PVD coating machine, which uses physical methods to vaporize the surface of the material source (solid or liquid) into gaseous atoms, molecules or partial ionization into ions, and deposits a film with a special function on the surface of the body through a low-pressure gas or plasma process. This equipment is mainly composed of a vacuum pumping system and an evaporation chamber. The vacuum pumping system consists of ultra-high vacuum pumps, low vacuum exhaust lines and valves to create and maintain a high vacuum environment. The evaporation chamber is mostly made of stainless steel and is equipped with components such as evaporation source, paint sheet, evaporation space and baffle to control the flow of evaporating atoms. Vacuum evaporation coating machine has the characteristics of high precision and high efficiency, widely used in plastic, metal, ceramics, synthetic resin, wood and other products surface treatment.
Two, vacuum sputtering coating machine
Vacuum sputtering coater is another common PVD coater. It uses high-energy particles (such as ions) to bombard the target, so that the target atoms or molecules are sputtered out, and deposited on the surface of the substrate to form a film. This coating method can obtain a more uniform and denser film, and is suitable for plating a variety of complex metal, alloy and compound films. Vacuum sputtering coater has a wide range of applications in industrial production, especially in the need of high precision and high wear resistance.
Three, vacuum ion coating machine
Vacuum ion coater is one of the fastest growing PVD coating technologies in recent years. It combines the advantages of evaporation coating and sputtering coating, and uses plasma technology in the coating process to ionize the film material and accelerate the bombardment to the substrate surface, so as to achieve the coating effect of high quality, high hardness and high adhesion. Vacuum ion coating machine is widely used in the surface treatment of various industrial products, such as decoration, metal cutting tools, architectural glass, automotive glass, flat panel display and so on. In addition, it can also be used to make anti-counterfeiting film, aircraft protective coating and so on.
In summary, PVD coater can be divided into three categories according to its working principle and technical characteristics: vacuum evaporation coater, vacuum sputtering coater and vacuum ion coater. Each type of coating machine has its own unique application areas and advantages, and users can choose according to their specific needs and budgets.
