Small Parts Coating Painting Machine PVD Vacuum Plating Equipment
Our Small Parts Coating Machine is a specialized PVD (Physical Vapor Deposition) vacuum plating system designed for batch processing of miniature and precision components. Integrating cathodic arc evaporation and magnetron sputtering technologies, it applies hard, wear-resistant, decorative, or functional coatings onto small parts such as fasteners, cutting tools, jewelry, watch cases, electronic connectors, and medical instruments. The system features a rotating barrel or planetary fixture to ensure 360° uniform coverage, even for complex geometries.
Features
Dual Deposition Technology: Combines arc evaporation for dense, highly adhesive coatings (e.g. TiN, CrN, AlTiN) with sputtering for smooth, defect-free decorative films (e.g. gold, rose gold, black).
Optimized for Small Parts: Specialized substrate holders including rotating cages, barrels and multi-level planetary trays that tumble or rotate parts for uniform coating without line-of-sight shadowing.
High Vacuum and Fast Cycle: Ultimate vacuum <= 6.7 x 10^-4 Pa; pump-down time < 15 minutes. Typical coating cycle: 2 to 4 hours per batch depending on thickness and material.
Precise Process Control: PLC and HMI touchscreen with fully automated recipe storage for gas flow, bias voltage, arc current and deposition time. Real-time monitoring and data logging.
Excellent Coating Properties: Hardness up to 40 GPa (e.g. AlTiN), coefficient of friction as low as 0.2, corrosion resistance salt spray test >120 hours, and available colors including gold, rose gold, black, blue and rainbow.
Energy and Cost Efficiency: Optimized chamber design reduces pumping and heating losses. Small batch size (10 to 150 kg per cycle) minimizes energy per part.
Eco-Friendly: Closed-loop water cooling, no chemical waste, meets EU RoHS standards.
Available Fixtures for Small Parts
| Fixture Type | Best for |
|---|---|
| Rotating Barrel | Tiny parts: screws, nuts, pins, electronic terminals, balls |
| Planetary Trays | Flat or slightly complex parts: watch cases, jewelry, medical instruments |
| Spindle and Cage | Parts requiring minimal contact: drills, end mills, cutting inserts |
Custom fixtures available upon request.

| Common Coatings | Features |
| TiN | TiN (Titanium Nitride) This coating has become the choice for general machining and wear applications. It works well when shops are machining carbon steels and stainless steels. The coating is also a favorite for decorative items that need a gold appearance and good wear resistance. Injection molders find it works superior to chrome and nickel wet bath platings for release, wear and corrosion protection. Rubber molders have found the coating to provide better release and corrosion properties than wet bath platings. |
| TiCN | TiCN (Titanium Carbonitride) This coating provides higher abrasion resistance and a lower friction coefficient than TiN, CrN and TiAlN but it has a lower temperature threshold. It is superior to the TiN when machining stainless steels, high nickel alloys, cast iron, non-ferrous materials and plastics. |
| AlTiN | AlTiN (Aluminum Titanium Nitride) This coating has the highest temperature resistance of any of the coatings available. It also provides a high degree of surface hardness and maintains that hardness at elevated temperatures. It is the coating of choice when you are dry machining, machining titanium alloys, inconel, stainless alloys and cast iron. The advantage of the AlTiN film is its ability to produce the Al2O3 when high temperatures are encountered. |
| CrN | Chromium Nitride A good tribological coating and the best coating for corrosion protection CrN is a versatile performance coating. On steel substrates our CrN coating provides improved adhesion, oxidation resistance and corrosion protection compared to titanium based coatings. In difficult, demanding forming applications CrN has excelled in providing increased tool life. If you are machining titanium CrN will provide you with increased tool life under specific operating conditions. The die casting industry has experienced remarkable gains in tool life due to the protection from heat checking and die wear provided by the chromium based coatings. Injection molders have also experienced improved performance when using the CrN coating in place of wet bath hard chrome plating. |
| ZrN | ZrN (Zirconium Nitride) This coating has become the choice for machining, forming or punching nonferrous materials and plastics. It can also be used to machine cast iron alloys as well. The coating is a favorite for decorative items that require a brass appearance and good wear resistance. ZrN can be used as a barrier film for corrosion protection.. |
