Introduction To The High Vacuum Coating Machine
What Is Vacuum Coating?
Vacuum Coating is a thin film technology for applying films to thin coatings by creating an atmospheric environment with a source of atomic or molecular air. Physical vapor deposition (PVD) and chemical vapor deposition (CVD) are considered to be the most attractive vapor deposition technologies. The most common PVD coating process is sputter deposition and evaporation.
The Structure Of The High Vacuum Coating Machine
Auxiliary Pumping System
The process of exhausting is as follows: the pump first heats the room to the bottom of the cavity below about 2.0 * 10-2PA, which provides the necessary conditions for installing the pump on the next body. Then, when the diffusion pump absorbs the room, the machine works together with the oil to be dispersed. The pumps are connected in series.
The Vacuum Body- The Vacuum Chamber
According to the different requirements of these products, the size of the hole is different. Commonly used room lengths are 1.3 m, 0.9 m, 1.5 m, 1.8 m, etc. The frame of the house is made of stainless steel, which is strong and rust-free. Each part of the house has a connection valve for the connection of different pumps.

Booster Bump
A booster pump, also known as a submersible pump, is a mechanical device with a pair of high-speed rotating bi-lobed or multi-lobed rotors. Since it works in the same way as a root blower, it can also be called a booster pump. The pump has a high pump capacity and a pressure range of 100-1 Pa. This pump cannot work in air, its function is only to make the difference between air and air. pump to complete. Therefore, it must be used in a mechanical pump.
Mechanical Pump
A mechanical pump is usually used with a small pump hole. It uses oil to maintain the seal effect and relies on a mechanical system to change the volume of the vacuum tube and pump. The volume of the gas expands continuously to achieve a vacuum state.
Oil Diffusion Pump
The optimum working pressure of the mechanical pump is only 10-2 Pa. When it reaches 10-1 Pa, the actual pump speed is only 1/10 of the standard value. If you want to get a higher clearance, you have to use an oil pump.
The Use Of The High Vacuum Coating Machine
A vacuum coating generally heats the evaporation pellet as the sweat on the surface material in an atomic or ionic manner. Then, it is applied to seeds to create a film. In the case of PVD plating process, during the process, electrons or high-energy lasers are used to throw the desired material, and the surface material is ignited by atomic groups and it is an ion, and finally it is placed on the surface of the substrate to form a film.
Features Of High Vacuum Machines
The vacuum coating equipment uses a box-type structure, and the ventilation system is installed on the back. Easy operation and maintenance. The entire surface is smooth and easy to clean.
The air system of the air conditioning machine has the advantages of high pumping speed, short pumping time, large space and small production cycle.
The page is rotated from the top center. The water is cooled and sealed magnetically. The conversion is stable and reliable.
The vacuum coating machine uses an advanced coating control system, the operation interface is beautiful and convenient, the system is stable and reliable, and the system can be operated manually, the medium is automated and fully automated.
