How Does Electropolishing Work?

Metal parts need to be in exceptional condition for enhanced performance and cycle-life value. Without a proper finishing treatment, your parts could be at risk. The solution? Electropolishing. Companies in industries like aerospace, automotive, dental, medical, pharmaceutical and more utilize electropolishing as the “final step” of the manufacturing process to enhance the performance of their metal parts. At Able Electropolishing, we understand electropolishing may seem confusing, which is why we’ve broken down t

Electropolishing or Passivation: An Infographic Guide

If you aren't familiar with electropolishing, the differences between this process and the passivation process may not be immediately clear. While both are metal finishing operations that treat parts in a chemical solution and improve corrosion resistance, they are drastically different in many other ways. From the metals these processes can treat to the benefits they provide, electropolishing and passivation are considerably different. To help explain the differences between the two, the team at Able Electropolishin

How to Distinguish Metal Parts

Whether for internal or external use, a system of identification is highly useful for distinguishing like parts. Establishing and adhering to such a system enables you to quickly and easily organize metal parts, but you must ensure that your method is useful under different conditions. Printed sticker labels or tags, for example, can wear off over time especially when exposed to moisture. A process like laser marking, on the other hand, is a permanent solution. Laser Marking Benefits Laser marking is a process commonl

How Much Microfinishing is Enough?

The electropolishing process is renowned for its ability to improve a metal part's microfinish, reducing the surface irregularities and imperfections to create a smoother, better-performing part. Because electropolishing is more precise than other metal polishing methods, it can be used to remove a small amount of surface material, reducing the microfinish value as much as necessary without altering the size and shape of the part more than its tolerances allow. Determining Microinch Value The first step is to determ

Electropolishing-Both Functional and Decorative

While its benefits include improving corrosion resistance and eliminating surface contamination, one of the most immediately recognizable benefits of electropolishing is decorative. This is because the electropolishing process actually strips away a consistent layer of surface metal from a part, eliminating a wide variety of surface impurities like embedded scale, heat discoloration, debris, oils and more. The Ultracleaning Process Electropolishing provides an ultraclean surface, so named because all types of surfac

Why Is Electropolishing Used for Medical Devices?

Medical devices, tools and implantable items are used for highly sensitive procedures, and therefore must be expertly finished before they are utilized. Burrs on a cutting implement can break off inside a patient, an implantable device can corrode inside the body and a critical mechanical device can seize up and jam when it's needed the most. To avoid the bodily harm that can result from improperly finished parts, medical device electropolishing is becoming increasingly popular. What does this process do, though, that m

Is Electropolishing Safe for Food & Beverage Industries?

Metal parts used by the food and beverage industries are subjected to heavy use, harsh environments and potentially corrosive cleaning chemicals on a regular basis. Because of this, these industries rely heavily on metal finishing operations that can improve the life of their parts while ensuring their safety and aesthetics. Does electropolishing provide the benefits that they need? Removing Heat Tint When stainless steel parts like wire racks are welded, it leaves discoloration that can negatively impact their corr

What are the Benefits of Titanium Anodizing?

In addition to electropolishing, titanium can benefit from a range of other finishing treatments, including color anodizing. Titanium anodizing is a process that builds up a layer of oxide on the surface of the metal part, which causes an interference in reflecting lights that creates a colorful appearance. Unlike dyes or coatings, anodizing doesn't add any foreign materials to your parts—and its benefits go beyond the cosmetic. Decorative Benefits The most immediately recognizable benefit of titanium anodizing is t

What is the Notch Effect, and How Does Electropolishing Eliminate It?

Even a metal part that looks flawless to the naked eye can have micro imperfections that drastically shorten its fatigue life. Parts that bend and flex, like springs, are particularly vulnerable to the notch effect, which can cause part failure before they last as long as estimated. What is the notch effect, exactly, and how can electropolishing stainless steel and other metal parts prevent it from causing premature part failure? The Notch Effect, Explained The basic principle of the notch effect is simple: A part wit

Does Electropolishing Wear Off?

When comparing electropolishing to other metal finishing operations, like plating and  coatings, one frequently asked question is whether it wears off over time.  The finish resulting from electropolishing will last indefinitely and will not chip, peel or abrade like platings and coatings.  If over time, as a result of physical damage, the electropolished surface requires refurbishing or re-machining, there is nothing to strip or remove prior to accomplishing this. The "Reverse Plating" Process Unlike processes lik
