Ultra cleaning and Decorative Finishes

Electropolishing for Ultra-Cleaning & Decorative Finishes

Electropolishing is best known for its ability to produce a bright, mirror-like finish but there’s far more to it than just good looks. Beneath the shine lies one of its most important benefits: deep surface cleansing. Because electropolishing removes a thin layer of surface metal, it also eliminates virtually all surface contaminants leaving parts ultra-clean and free from embedded debris, grinding residue, dust, oils, and even polishing compounds.

This makes electropolishing the ideal process for applications where cleanliness, precision, and corrosion resistance are critical.

Clean, Precise, and Ready for Use

Electropolishing is especially effective at removing heat tint and oxide layers from welding or heat treatment. By selectively removing surface material, we can eliminate even deeply embedded contaminants. Once processed, your part is clean, passive, within tolerance, and ready for assembly no further finishing required.

Why Choose Electropolishing?

No Coatings, No Flaking

Unlike paints, platings, or Teflon, electropolishing doesn’t add anything to the surface it refines the existing one. That means there’s nothing to peel, chip, or abrade over time. This is a major advantage in industries where flaking materials can cause contamination or failure, such as food production, pharmaceuticals, cleanrooms, or high-vacuum systems.

Non-Distorting
Electropolishing is gentle on parts. There’s no mechanical stress, no distortion, and no risk of damaging fine details or delicate shapes. It’s perfect for fragile or intricate components where traditional polishing just won’t work.
Enhanced Corrosion and Stain Resistance

By smoothing out the surface and removing impurities, electropolishing significantly boosts resistance to rust, tarnish, and oxidation especially in stainless steel, but also in copper, brass, aluminum, and carbon steel. While it’s not a full replacement for heavy-duty coatings in harsh environments, it still adds a valuable layer of protection.

Improved Weldability
Electropolished parts often weld better and cleaner. In precision spot welding, for example, improved conductivity allows for stronger welds at lower voltages. The smooth surface also means less weld spatter and reduced surface damage in brazing or fusion welding operations.

Why Choose Electropolishing?

One customer brought us a switch component made from a soft beryllium-nickel alloy. The part had fine ribs cut by wire EDM, shaped, and heat-treated. It showed visible contamination and recast material under 100x and 500x magnification—all of which needed to be removed without damaging the fragile structure. Due to the delicate nature of the alloy and tight dimensional tolerances, mechanical cleaning methods weren’t an option. Chemical etching was also ruled out because of inconsistent material removal.
Using precise material removal control, we eliminated surface and sub-surface contamination across the entire part. Even the amorphous layer from EDM processing was removed, revealing clean, base metal. The final result met strict cleanroom standards and, thanks to the stress relief provided by the process, extended the part’s life under high-cycle switching conditions.
