Electropolishing Applications

When you need parts to have a consistent finish, free of imperfections, electropolishing can be an ideal process for your company’s small metal parts.

What is Electropolishing?

Electropolishing is a metal treatment process, often referred to as a “reverse plating process,” that electro-chemically removes the outermost layer of metal to create a uniform surface. Unlike other mechanical polishing processes, electropolished parts aren’t tumbled or vibrated, eliminating the risk for uneven surfaces. Instead, electropolished parts are immersed in a chemical bath, which removes a uniform layer of material and eliminates embedded contaminants and micro defects.

The Benefits of Electropolishing

A common purpose of electropolishing is to remove surface material in a systematic fashion in order to remove defects that can only be seen at a microscopic level. By having your parts electropolished, they will be more resistant to cracking and corrosion, making your parts more reliable and long-lasting. Although less common, you may have your parts electropolished for cosmetic reasons. Once metal products undergo electropolishing, they are cleaned, brightened and polished for an overall improved aesthetic appeal.

Common Applications

Because so many industries, including medical, dental, pharmaceutical, aerospace and more, utilize electropolishing for their products, it has become a common finishing procedure for many small metal parts, including:

  • Fasteners – Ideal for deburring threads, reducing galling, and improving corrosion resistance; it is especially useful for marine applications.
  • Springs – Ideal for reducing or removing cracks and fissures created during forming, as well as preventing premature product failure.
  • Wire racks – Ideal for removing weld discoloration and creating a clean, attractive, sanitary finish, as well as for improving corrosion resistance at the weld joints.
  • Blades – Ideal for creating a sharp, smooth surface. By removing, stamping, and grinding burrs, it eliminates the chance that flecks of metal will dislodge from the part.

The Benefits of Electropolishing for 440C Stainless Steel

If you’re manufacturing parts with 440C stainless steel and relying on passivation to get the finish you need, you may be overlooking an opportunity to dramatically improve the corrosion resistance of your parts.

Electropolishing for Better, More Durable Plated Parts

While electropolishing is best known for the results it achieves as the last step in the process for finishing critical metal parts, it can also be an interim step for improving the results of parts that will undergo plating.

Biocompatibility and Electropolishing for Medical Manufacturing

The biocompatibility of medical devices, implants and instruments to ensure that every part that comes into contact with the human body poses no risk of irritation or harm is a fundamental requirement for medical manufacturers.
