When consid­ering a metal finishing process to solve common metal surface problems, submitting a sample for processing can be a great opport­unity to learn the types of results the selected method will yield as well as how it will affect your metal components themse­lves. If you’re working with protot­ypes, submitting a sample for processing should be your first step to ensure that the process will result in an optimal finish for the intended applic­ation.

lectro­pol­ishing offers a variety of benefits including improved corrosion resist­ance, deburring, ultrac­lea­ning, microf­inish improv­ement, and more. Here are the basics you’ll need to provide when submitting a sample part for proces­sing:

1. Describe the Current Surface Problem

Electr­opo­lishing can resolve or improve many of the most common metal surface problems. Unders­tanding the exact surface problem your components are suffering from is a critical for identi­fying the best final finishing method that will address your issue. Whether your parts are experi­encing premature part failure, corrosion problems, contain burrs, or have microf­inish problems, it’s important to descri­bethe exact problem when submitting your parts for electr­opo­lis­hing.

2. Indicate Present Solution to Surface Problem

In addition to describing the surface problem of your parts, it’s important to know what current finishing method you are using to address it. This will provide a baseline and a comparison for results achieved from electr­opo­lis­hing.

3. Provide Info Regarding Compon­ent’s Material

While Able Electr­opo­lishing can electr­opolish nearly any metal alloy – from the stainless steel families to titanium - it’s important to know the exact compos­ition ofyour compon­ent’s material. Some alloys may not be suited for electr­opo­lishing do to their inherent proper­ties. Unders­tanding the compos­ition of your components is critical when first trying out electr­opo­lishing as a metal finishing option.

4. Indicate Special Tolerances

If your parts have close dimens­ional tolera­nces, it’s important to indicate those dimensions that need to be monitored when submitting your parts for electr­opo­lis­hing. Since electr­opo­lishing removes a uniform layer of the metal’s skin, it’s important to understand the final required size your parts must meet to ensure that even after electr­opo­lis­hing, your parts are still within the specif­ica­tions.


5. Include Prints of Your Parts

Including a print of your parts showing part number, descri­ption, dimens­ions, tolerances and critical areas is extremely helpful in order to process your parts properly. Without this detail provided, your parts may be contacted on a critical area or the material removal will be incorrect.

6. Identify Multiple Qualities (if Needed)

If you’re looking to see multiple qualities to test the effect­iveness of electr­opo­lishing or to evaluate the effect on your parts, you can submit multiple parts. You may want to request that samples be processed with different amounts of material removal or different rack locations. To sample different qualities, be sure to send in multiple parts and indicate what you are trying to achieve with your samples.

7. Provide Packaging Requir­ements

For many parts, packaging is critical. Fragile components or components used in highly sanitary applic­ations will require specialty packaging to ensure that your parts are returned properly without compro­mising the part config­uration or finish. It is important that you indicate the preferred packaging method when submitting your samples
