Jewelry PVD Coating Machine

Jewelry PVD coating machine is a physical vapor deposition equipment specially designed for the jewelry industry, which is used to coat a very thin but high-performance film layer (such as gold, rose gold, black gold, platinum, colored titanium nitride, etc.) on the surface of jewelry.

This jewelry PVD coating machine integrates both of multi-arc ion plating and magnetron sputtering together, which is specifically designed for decorative coating in the jewelry industry. It is very good at depositing both decorative colored coatings and hard functional coatings.

Equipment Features

Dual-technology integration: multi-arc ion plating + magnetron sputtering 
Multi-arc ion plating offers high deposition rates and good adhesion

Magnetron sputtering produces fine, smooth coatings and supports the deposition of single-layer, multi-layer composite, and alloy films.

Capable of producing coatings such as TiN, TiCN, CrN, DLC (diamond-like carbon), and Au (gold) films.

Low-temperature ion-assisted cold plating process
Equipped with a low-temperature ion-assisted source, this process enables coating at room temperature without high-temperature heating of the workpiece,which can be preventing deformation of the jewelry substrate.

Fully Automatic Precision Control System
Integrated control method of industrial PC ensures precise regulation of vacuum levels, gas flow rates, target power, and coating duration.

Planetary Rotation Fixture 

The vacuum chamber inner is equipped with a planetary rotation fixture, which can ensure the
uniform coating of the workpieces.

Both of the inner and outer surfaces can be covered evenly with the coating layer.

Independent high-precision flow control for process gas, combined with multi-gauge vacuum monitoring.

The equipment is equipped with protective functions against water shortage, over-temperature, over-pressure, and power failure.

Rich coating color options
Available finishes include furnace gold, rose gold, gunmetal black, iridescent blue, antique bronze, silver, and black-gold.
custom-tailored matte and glossy textures are also supported.

Fashion jewelry
Stainless steel,titanium steel,brass,silver rings,necklaces,bracelets, stud earrings,pendants and jewelry accessories.

 

Affordable luxury hardware
Watch cases and straps,eyeglass frames, leather goods clasps and luggage hardware.

 

Small bathroom hardware and decorative ornaments
Coatings for small ceramic and glass art pieces.

Functional coating requirements
Wear-resistant and anti-fingerprint coatings for jewelry,DLC (Diamond-Like Carbon) ultra-hard protective films to enhance sweat and corrosion resistance.

 

Substrate compatibility
Stainless steel, titanium alloys, copper alloys, silver, ceramics and certain specialty plastics.

 Principle of Physical Vapor Deposition
The entire process mainly involves physical changes and basically does not use harmful chemical solutions.

 Low temperature process
Most jewelry PVD coating processes can be completed at relatively low temperatures

This is critical for jewelry materials that are not resistant to high temperatures to avoid deformation of the material or damage to the gemstone.

Rich coating types
By choosing different targets (pure metals such as gold, silver, chromium; alloys; compounds such as TiN, ZrN, TiC, TiCN, etc.) and introducing different reaction gases (such as nitrogen, oxygen, acetylene, etc.), extremely diverse colors and effects can be deposited.

Excellent film performance
High hardness and wear resistance:

Especially ceramic film layers such as titanium nitride, which have a much higher hardness than gold itself, can significantly improve the scratch resistance and wear resistance of the jewelry surface and maintain long-lasting gloss.

Excellent adhesion

The film layer is firmly bonded to the substrate (gold, silver, copper alloy, stainless steel, etc.) and is not easy to peel off.

Good corrosion resistance

Can effectively resist corrosion from sweat, cosmetics, air, etc., extend the service life of jewelry and maintain color.

Good biocompatibility

Commonly used membrane materials (such as titanium, zirconium, gold and their compounds) usually have good biocompatibility and are suitable for skin contact.

Good uniformity and coverage

Even complex shapes (such as ring inner walls, grooves, and fine textures) can achieve relatively uniform coating coverage.

Dense and pure coating

The vacuum environment reduces impurity contamination, and the formed membrane layer has a dense structure, low porosity, and more stable performance.
