What is Electropolishing?

Electropolishing is a subtractive electro chemical process which removes material from a metallic product. It can also be called electrochemical polishing or electrolytic polishing but the process is the same. It is used to polish, passivate, and deburr metal parts and is used instead of abrasive processes for metal finishing. The end result is a cleaner, smoother and shinier finish on metal parts.

What Makes us Different?

Our attention to detail. We understand that electropolishing is probably one of the last process for your product and any error is at a cost of all of the previous steps. We will talk you through the electropolishing process and try to eliminate any errors before they occur. Our experience in the medical manufacturing field has taught us how to be precise.

At Classic Electropolishing, stainless steel is the most common product that we electropolish but we are able to do a variety of metals. We provide electropolishing to the highest standards and we adhere to ASTM B 912-02 (2008), Passivation of Stainless Steels Using Electropolishing.

Classic Electropolishing proudly serves advanced medical, automotive, aerospace, food and electronics manufacturers.
