The Vacuum Evaporation Coating

- May 15, 2020-

The vacuum evaporation coating heats the coating material in a vacuum environment, causing it to evaporate in a very short time. The evaporated coating molecules are deposited on the plastic surface to form a coating layer. This method is simple, convenient, easy to operate, film forming speed, high efficiency, is the most widely used technology in thin film vacuum preparation, but the thin film and the matrix is poor, the process repeatability is not good, can only evaporate aluminum such as low melting point metal.
