The vacuum coating furnace uses a vacuum system in a specific space of the furnace cavity to discharge some of the substances in the furnace cavity, so that the pressure in the furnace cavity is less than a standard atmospheric pressure, and the space in the furnace cavity is thus in a vacuum state.

When the vacuum work is performed during use, the vacuum pump will discharge the raw materials diffused in the inside of the device out of the device, thereby affecting the coating quality of the device.
