Vacuum Plating

Vacuum vapor deposition: Under high vacuum, thin layers of metal are attached to the plastic surface through evaporation and condensation of metal filaments. During the process of vacuum vapor deposition, the metal (most commonly aluminum) is melted and evaporated in just a few seconds, and the whole cycle generally does not exceed 15s, with a layer thickness of 0.8-1.2uM.

Design of vacuum evaporation plastic products should avoid large flat surfaces, sharp corners and sharp edges. Concave and convex patterns, textures or arched surfaces work best. Vacuum vapor deposition is difficult to obtain an optically flat-like product surface.

Vacuum plating surface is plated with lacquer, and water plating surface is plated with metal layer.

The surface hardness of vacuum plating is lower than that of water plating, and the wear resistance is also lower, and it is easy to age and lose color in sunlight, but the pollution is less. Vacuum plating is not conductive

Currently, water plating is used in heavy industries (automobiles, etc.), while vacuum plating is widely used in household appliances and cosmetic packaging.

If the hardness of vacuum plating can reach the level of water plating, then water plating will disappear.

At present, many cell phones use PVD vacuum ion plating, which not only can provide beautiful color but also good wear resistance. But it is more expensive and costly.
