Vacuum Pump in Coating Technology

In terms of coating technology, what are the application aspects of vacuum technology?

Vacuum technology plays a decisive role in many coating processes, such as vapor deposition of metals, plastics or glass. In many cases, these processes cannot be realized without vacuum. Generally, at the beginning of the process, a medium or high vacuum is applied to the chamber to exhaust the vacuum, then the reaction gas or gasified solid raw materials are extracted.

These coating processes have a common requirement: the chamber must be kept in a medium or high vacuum which fully meets the requirements of the coating process. These coating processes help to change the surface characteristics of the material, such as hardness or corrosion resistance. In addition, vacuum coating can also improve the adhesion or wettability of materials, or make the surface of materials maintain maximum hydrophobicity or hydrophilicity.

We provide a large number of vacuum solutions for different coating processes. In addition to independent vacuum pumps, we also supply a full set of vacuum systems. Single-stage rotary vane vacuum pump is especially suitable for coating process. Practice has proved that rotary vane vacuum pump combined with Roots vacuum pump is a standard solution for medium vacuum coating application. Various types of variable pitch screw vacuum pumps and Roots vacuum pumps can also be provided, so that the design of the vacuum system can fully meet the requirements of the coating process. If high vacuum is needed, we have turbomolecular vacuum pump and diffusion vacuum pump, which can be combined with the front pump to meet the coating process requirements.
