Prepping Your Metal Parts for an Electropolishing Finishing 

The road to the final product of a crafted metal piece is long, but often, the most important part of the metal crafting process is its finishing. The finishing process and the techniques used determine what the final product of the metal will look like – it determines how the surface appears and behaves when put to industry use.

In order to craft materials that are in compliance with industry standards, the finishing process used on the metal is important to ensuring durability and cleanliness – two characteristics of the finished metal that are growing more and more crucial in today’s work environments.

If you determine that electropolishing is the most appropriate finishing method for your metal parts, there are a few steps you can make to prepare your parts for the treatment before sending in bulk parts to production.

Prep Your Metal by Removing Larger Surface Imperfections  

While electropolishing will create the foundation for a beautifully reflective and shiny surface, it’s important to remove any scratches, macro burrs, and any traces of adhesive, coatings, or lubricants from your metal part prior to sending it for electropolishing finishing treatment.

Ensure Metal Welds are Uniform, Clean, and Airtight

Does your metal part have welds? Before undergoing the electropolishing process, it’s important to ensure that all welds have been cleaned and that they are uniform and airtight. Without an airtight seal, fluids can become trapped beneath the surface or in crevices. Once left to sit, they can be very difficult to remove post-treatment.

Know Your Desired Ra Value Prior to Electropolishing

Your microfinish value, or Ra value, determines how rough—on a micro level—the surface of your metal part will be post-finishing treatment. Understanding your desired Ra value and texture of the finished metal will better help your production team treat your parts. Depending on your preferences, your production team may suggest additional treatments to achieve the desired Ra value.
