Electropolishing Removes. Electroplating Adds.

Electropolishing is often confused with electroplating, but the processes work in opposite ways.

Electroplating deposits a coating onto a metal surface. Electropolishing removes a microscopic, controlled layer from the existing stainless steel surface.

By reducing microscopic high points and surface imperfections, electropolishing can create a smoother, brighter and more uniform surface. It can also reduce small burrs, improve cleanability and support corrosion resistance.

Electropolishing is not a coating. It changes the surface of the existing metal.

Process Control You Can Document

Quality and repeatability matter whether we are processing one large fabrication or a high-volume run of small components.

We mix and maintain our electropolishing electrolyte in-house. This gives our team direct control over a key part of the process and helps us maintain consistent processing conditions.

Depending on your project requirements, we can also maintain processing records and provide a Certificate of Performance documenting the work completed.
