Definition and Function

Vacuum plating is a surface treatment technology that deposits a thin metallic or metallic-luster coating on a substrate in a vacuum environment through evaporation, sputtering, or ion plating (PVD).
A high-gloss topcoat is then applied to enhance surface gloss, protect the metal layer, and improve the overall appearance.
This combined process provides strong metallic luster, high reflectivity, excellent decorative effect, and improved wear, oxidation, and weather resistance.
It is widely used in automotive trim, household appliances, cosmetic packaging, electronic housings, and high-end decorative parts.

Colors

Silver

Gold

Black Chrome

Vacuum plating allows a wide range of metallic colors such as silver, gold, black chrome, titanium, and rose gold.

The addition of high-gloss paint enhances brightness, color stability, and durability. Typical finishes include:

High Gloss Silver – mirror-like bright silver, high reflectivity.
High Gloss Gold – rich, bright gold with strong visual impact.
High Gloss Black Chrome – deep metallic black with a premium look.
Color Coating – multi-color effects achieved through paint or interference film.
