Jewelry Vacuum Coating (PVD)

Jewelry PVD is a type of physical vapor deposition vacuum coating. In a sealed high-vacuum furnace, target materials such as gold, titanium, zirconium, and chromium are ionized into atoms or ions, which are then uniformly deposited onto the surface of jewelry to form an ultra-thin metallic film. This replaces traditional electroplating and offers advantages such as wear resistance, colorfastness, environmental friendliness, and rich colors. It is widely used for stainless steel, silver, copper alloys, titanium steel jewelry, K-gold enhancement, and jade and pearl jewelry.

Two Mainstream Vacuum Coating Equipment in the Jewelry Industry

Multi-Arc Ion Plating Machine: The mainstay of jewelry mass production; the preferred choice for stainless steel and alloy materials.

Multi-arc ion plating equipment utilizes a cathode arc target to instantly ionize the target material at high temperature. High-density metal ions bombard the jewelry at high speed under a bias electric field, resulting in extremely strong film adhesion and fast deposition speed. It is suitable for mass production of bracelets, necklaces, rings, and complex openwork jewelry. It is also suitable for affordable stainless steel jewelry, silver jewelry anti-oxidation, hardware accessories, and watch straps.

Another type of coating equipment is the unbalanced magnetron sputtering coating machine: specifically designed for high-end jewelry and mirror-finish ornaments.

Magnetron sputtering equipment utilizes a magnetic field to confine argon ions to bombard the target material, resulting in smooth sputtering deposition of target atoms without arcing or droplets. The resulting film is extremely smooth, mirror-like, delicate, and transparent, capable of replicating the matte texture of 18K gold, platinum, and antique gold, and can also create iridescent and gradient two-tone jewelry.
