Metal Finishing Processes

Nickel Plating

  • Bright
  • Semi-Bright
  • Sulfamate

Black Oxide Coatings

  • Hot or cold options
  • Powder or liquid additives

Tin Plating

  • Bright
  • Matte
  • 60/40 Tin Lead
  • 90/10 Tin Lead

Electroless Nickel Plating

  • Phosphorous content requirements – 1%-5% low phosphorous, 6%-9% mid phosphorous, 10%-12% is high phosphorous
  • Deposit brightness – deposits can be dull, semi-bright or mirror bright depending on customer requirements
  • Production requirements – mid phos can plate twice as fast on a new make-up
  • Corrosion resistance – 1 mil of high phos should give 1000 salt spray hours, 1 mil of mid phos should give 100 hours
  • Composite coatings – EN Teflon, EN Boron Nitride, EN Diamond

Zinc Plating

  • Alkaline Zinc – Cyanide free bright deposit, great throwing power with excellent corrosion protection
  • Acid Zinc – Excellent brightness, operates with or without Boric acid, High temperature tolerance
  • Alkaline Zinc-Nickel – Superior corrosion protection, ease of use additives
  • Acid Zinc-Nickel – Excellent corrosion protection, high productivity
  • Passivates – Clear, Clear blue, Yellow, black and CR (VI) – free
  • Sealers- Organic or inorganic
