Electro Polishing

is a “reverse plating” process that uses an electrochemical solution to remove the outer skin of a metal part. …Electropolishing stainless steel significantly improves a part’s corrosion resistance, leaving it with a lasting bright finish.

Some Industries that use electropolish:

  • Dental, Medical and Orthopedic Equipment
  • Aerospace Equipment
  • Bio Pharmaceutical
  • Food Processing
  • Food and Beverage

Common Parts that are electropolished:

  • Stainless Steel Pump Parts
  • Springs, Nuts + Bolts
  • Fittings + Piping




Why Electro Polish?

The electropolishing process may improve a surface finish by up to 50%. The electropolishing reaction removes material while it improves surface roughness. Because of the material removal, process runtimes are often limited to maintain dimensional tolerances.

How is electropolishing done?

Electropolishing is an electrochemical finishing process that removes a thin layer of material from a metal part, typically stainless steel or similar alloys. The process leaves a shiny, smooth, ultra-clean surface finish. … Both are non-mechanical, chemical processes, but only electropolishing uses electrical current.

What is the difference between electropolishing and passivation?

Passivation is a chemical process designed to remove free iron and other contaminants from the part surface. Electropolishing is an electro-chemical process that removes surface metal which improves micro finish, provides deburring and adds to the aesthetics of your part.
