Multi-Color PVD Vacuum Coating Machine for Stainless Steel Kitchen Sinks

Transform stainless steel sinks into premium, colorful, and durable masterpieces.

Upgrade your sink production line with our advanced PVD (Physical Vapor Deposition) vacuum coating system – engineered specifically for coloring stainless steel kitchen sinks. Achieve brilliant, uniform, and long-lasting finishes in any custom shade, from classic brushed gold to matte black and beyond.

Today’s homeowners and designers demand more than plain silver stainless steel. They want sinks that match modern kitchens – bold, elegant, and easy to clean. Our vacuum coating machine lets you deliver exactly that, with coatings that outperform traditional paint or electroplating.

Scratch & corrosion resistance Surface hardness >2000 HV; withstands acidic foods and detergents
Eco-friendly process Zero wastewater, no toxic chemicals, minimal energy consumption
Consistent premium look No streaks, unevenness, or edge defects – perfect for high-end brands
 
How It Works – The PVD Advantage

Our machine applies a thin, decorative, and functional ceramic or metal-based coating in a high-vacuum environment. Here’s the simplified process for stainless steel sinks:

  1. Loading – Sinks are hung on rotating fixtures inside the vacuum chamber.

  2. Vacuum pumping – Chamber pressure is reduced to 10⁻³~10⁻⁴ Pa.

  3. Plasma cleaning – Argon ions bombard the surface to remove oxides and contaminants at the atomic level.

  4. Coating deposition – Target materials (e.g., Ti, Cr, Zr, stainless steel alloys) are vaporized and react with nitrogen or carbon to form hard, colorful compounds (TiN – gold, ZrN – champagne, CrN – silver, TiCN – dark gray, etc.).

  5. Cooling & venting – Finished sinks are ready for packaging in 15–30 minutes.

Cycle capacity: 3–4 sinks per batch (depending on sink size and chamber dimensions).

 
Benefits for Your Sink Factory
✅ Fast Color Changeover

Switch from gold to black in under 5 minutes via pre-stored recipes – ideal for small-batch, high-mix production.

✅ High Throughput, Low Operating Cost

  • Rotating planetary system maximizes loading density.

  • Target material utilization rate >80%.

  • Automatic process monitoring reduces operator labor.

✅ Flawless Edge Coverage

Unlike spray painting or dipping, PVD coats 3D edges, inner corners, and under-rim areas uniformly – no exposed bare steel.

✅ Zero Deformation

The process temperature is typically 150–250°C – well below the distortion point of stainless steel. No warping, no post-straightening.

✅ Durability That Sells

PVD-coated sinks resist:

  • 48+ hours salt spray test (ASTM B117)

  • 1000+ cycles abrasion test

  • Boiling water, lemon juice, coffee, and wine stains
