Seal Selection For Vacuum Coating Machine

The sealing form can be selected according to the degree of vacuum needed and the actual working needs.

After the seal has been water-cooled, its temperature is about 80°C, and individual parts can reach temperatures above 100°C. Therefore, we should choose the more ideal seal material.

For vacuum sealing rubber materials, in addition to requiring a smooth surface, no scratches, no cracks, but also require a low permeability and out-gassing rate, good heat resistance and oil resistance, but also have a certain degree of strength, hardness and elasticity Wait.
