1. What are some typical applications of PVD coating?
Applications of PVD coating include

  • Kitchen and bath fixtures (faucets, nozzles, showerheads, and other accessories)
  • Writing instruments
  • Door hardware
  • Jewelry
  • Automotive components
  • Musical instruments
  • Eyeglasses frames
  • Marine hardware
  • Firearm components
  • Medical equipment
  • Golf clubs and other sporting goods

2. What substrates can be PVD coated?
ECF can apply PVD coatings on a wide variety of substrates including plastics such as ABS, polycarbonate, and PC-ABS; all common metals and alloys; glass; and ceramics.

3. Is a surface finish required to PVD coat a product?
PVD coating can be applied directly to stainless steel and titanium; however, other substrates must be nickel or chrome plated before PVD coating can be applied. Because PVD coating conforms to the surface of the substrate, plating is necessary to ensure a smooth surface for coating. Plating also provides corrosion resistance.

4. What are ECF’s PVD machine capabilities?
The PVD facilities at ECF include two industrial-sized PVD machines supplied by Hauzer Techno Coatings of the Netherlands. These vacuum chambers are made of stainless steel, and the space within the chambers can be evacuated to the order of 10-6 atm. within 15 minutes by using four turbo-molecular vacuum pumps.  Because of this high vacuum environment, coatings prepared within can attain very high purity, thereby reproducibility of specific color finish can be readily achieved, run after run.

5. What are ECF’s PVD machine capacities?
Each of our PVD chambers is capable of handling load volume of 5 ft. in height by 3 ft. in diameter, up to 2000 lbs.

6. What size parts can ECF PVD coat?
Our PVD carousels can accommodate parts up to 29 inches in length and 8.5 inches in width. Carousel spindles (which hold parts during coating) are custom designed according to specific part dimensions.

7. How can PVD finishes be cleaned?
PVD coated products can be cleaned with soft cloths, water, and mild soap. Cleaning products designed to remove tarnish or rust containing hydrochloric, hydrofluoric, phosphoric acid, or other caustic agents should not be used on PVD coatings, nor should bleach or scouring pads.
