Electropolishing & Passivation for Medical

Medical devices, tools and surgical implants have to function flawlessly within a life or death context. Every component of these products has to be manufactured to a microscopic level of precision and consistency. There is no metal finishing process that can achieve better results than electropolishing.

Whitepaper: Electropolishing for Safer, Cleaner, More Durable Medical Parts

Small microburrs, fissures, cracks, and other defects left behind by machining on the surface of metal parts create an environment susceptible to bacterial and viral growth. Without a defect-free, ultraclean finish, metal instruments, medical implants, and other devices pose a risk to patient health and safety. Read our whitepaper to learn why electropolishing creates the most passive, pathogen-resistant surfaces.

Precision Electropolishing

Electropolishing's ability to remove a microscopically precise surface layer with absolute consistency leaves critical metal parts with an ultraclean and ultrasmooth surface that inhibits the growth of pathogens and makes reusable devices easier to clean, without burrs, micro cracks and other surface imperfections that can trap liquids and debris and give harmful bacteria a place to hide.

In fact, electropolishing is so effective at optimizing the surface of medical devices and parts that we are often consulted for help in the prototyping phase to ensure that features are designed in ways that make electropolishing even more effective and avoid common design flaws.

What Can and Can’t Be Passivated?

Passivation is a widely used chemical finishing process to remove contaminants and improve the corrosion resistance of metal parts, including stainless steel and alloys like Nitinol and titanium. While passivation can be effective for many parts, for certain parts and…

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.
