Cosmetic bottles and caps metallizing vacuum coating machine

The working principle of the Cosmetic Bottles And Caps Metallizing Vacuum Coating Machine is mainly based on the metal evaporation and deposition process under a vacuum environment. The equipment uses a vacuum system to pump the coating chamber to a high vacuum state. At this time, the air pressure in the coating chamber is low, which provides good conditions for metal evaporation and deposition. Then the equipment heats the metal source material to the evaporation temperature through the heating system, so that metal atoms or molecules escape from the source material and form metal vapor. The metal vapor diffuses to the surface of the cosmetic bottle and bottle cap under a vacuum environment and condenses on the surface to form a metal film. The detailed working steps are as follows:
Vacuuming: After the equipment is started, the vacuum system starts to work and gradually extracts the air in the coating chamber until the preset vacuum degree is reached. The high vacuum state helps to reduce the interference of gas molecules on metal vapor and improve the coating quality.
Heating evaporation: When the vacuum degree reaches the requirement, the heating system starts to work and heats the metal source material to the evaporation temperature. After obtaining enough energy, metal atoms or molecules escape from the source material to form metal vapor.
Diffusion and deposition: Metal vapor diffuses freely in a vacuum environment. When it encounters the surface of the cosmetic bottle and bottle cap with a lower temperature, the metal atoms or molecules will lose energy and condense on the surface to form metal nuclei. With the continuous supply of metal vapor, the metal nuclei gradually grow and connect with each other, eventually forming a uniform and dense metal film on the surface.
