Electropolishing for Interior & Exterior Auto Parts

Electropolishing small, critical interior auto parts greatly reduces the threat of lingering metal shavings, burrs and embedded contaminants that can compromise a vehicle’s performance. The process removes a precise amount of surface metal from parts to brighten, deburr, improve corrosion resistance, and remove imperfections and contaminants left behind by stamping, tumbling and other manufacturing processes.

Auto manufacturers also need a process to remove weld discoloration and improve corrosion resistance of exterior metal parts. Electropolishing does all of this in one process, giving the stainless steel a uniformly bright, shiny and chrome-like appearance. Stringent salt spray and humidity tests show that electropolished parts have much higher ability to withstand corrosion and the effects of harsh elements like road salt, which causes corrosion and discoloration over time.

We recommend sending samples for electropolishing so that you can evaluate both finish and dimensional changes. If electropolishing is planned during the design stage, the material removal can be factored into your final size specifications.
