Magnetron Sputtering Vacuum Coating System for Automotive Wheel Rims – Gold / Silver / Chrome / Black Chrome Finishes
Upgrade your wheel finishing capabilities with our advanced Mid-Frequency Magnetron Sputtering Vacuum Coating System, specifically engineered for automotive wheel rims. This high-performance PVD (Physical Vapor Deposition) machine delivers premium metallic finishes – gold, silver, chrome, and black chrome – with outstanding adhesion, corrosion resistance, and consistent color uniformity. Ideal for OEM manufacturers, aftermarket wheel producers, and coating service centers seeking eco-friendly, durable, and high-gloss decorative coatings.
Features
Versatile Color Options
Achieve four popular finishes on a single system:
Gold – Luxury, high-end appearance
Silver – Classic bright metallic look
Chrome – Mirror-like reflective finish
Black Chrome – Sleek, sporty, and modern
Mid-Frequency Magnetron Sputtering Technology
Stable plasma discharge, no arc damage
High deposition rate for increased throughput
Excellent film density and smoothness
Eco-Friendly & Compliance
Zero hexavalent chromium, no heavy metal waste – fully complies with global environmental regulations (RoHS, REACH)
Dry, clean process – no toxic effluents or sludge disposal costs
Low energy consumption compared to traditional electroplating
Superior Coating Performance
Outstanding adhesion (scratch and peel resistant)
High hardness (≥ 8H) & wear resistance
Excellent corrosion resistance (salt spray test > 240 hours)
UV and weather resistance – retains gloss and color under harsh conditions
Designed for Wheel Rims
Large chamber capacity accommodates multiple rims per batch (e.g., 4–8 pieces, up to 24″ diameter)
Uniform coating on complex geometries – spokes, inner barrels, and edges
Programmable multi-layer structures (base + color + top coat)

Typical Process Flow
-
Loading – Mount wheel rims on rotating fixtures inside vacuum chamber.
-
Evacuation – Pump down to high vacuum.
-
Cleaning – Glow discharge plasma cleaning to remove surface contaminants.
-
Sputtering – Mid-frequency power sputters target material; metal ions deposit on rims.
-
Coloring – Introduce reactive gas (N₂, O₂, or C₂H₂) to achieve desired gold/silver/chrome/black chrome tone.
-
Venting & Unloading – Cool, vent, and remove finished rims.
All steps fully automated via user-friendly recipe control.
