6 Benefits of Electropolishing for Medical Device Manufacturing

By Pat Hayes, VP Business Development

Electropolishing is an electrochemical process that removes a microscopically precise layer of surface material from a metal part, resulting in an ultrasmooth, defect-free surface and enhanced resistance to corrosion, among other benefits. The process is a preferred finishing method among medical manufacturers due to its ability to improve the durability, cleanability and pathogen-resistance of metal parts.

The Electropolishing Process: How It Works

The electropolishing process involves immersing a metal part in an electrolyte solution while applying an electrical current to the bath. The electrical current reacts with the metal to dissolve surface impurities, removing a rough and uneven surface layer and revealing an ultrasmooth, ultraclean finish.

From microcracks and burrs to other surface defects, electropolishing eliminates impurities and leaves parts with improved cleanability, corrosion resistance, and…
