Electropolishing Service

Eliminate Burrs, Micro Cracks & Other Imperfections Left Behind in the Manufacturing Process


Electropolishing Example: Raw, Passivated & Electropolished

UltraClean_03aWhen you manufacture products like helicopters, medical implants and surgical instruments, food processing equipment, and other critical metal parts, you don’t have a lot of room for error. A microscopic imperfection in a single metal part can mean disaster.

Machining can leave parts with a wide array of imperfections: microburrs, microcracks, free iron, stains, heat tint, oxide scale, and other surface defects that can compromise the fit, finish, function, and durability of metal parts.

Electropolishing eliminates these surface defects by removing a microscopically precise layer of surface material, to tolerances as low as +/-.0001″, depending on the alloy. This degree of precision and consistency, along with the ability to remove a variety of surface imperfections in one process, is why electropolishing is so often specified for critical metal parts – with 30 times more corrosion resistance than passivation.

Electropolishing also eliminates the need for mechanical metal finishing processes like hand deburring, tumbling, pickling, and cleaning.
