Able Electropolishing in the News

Although the Food and Drug Administration (FDA) has reported progress on reducing overall infection rates with enhanced safety measures and better disinfection methods, the risks associated with reusable medical devices are an ongoing challenge, with drug-resistant microbes and other organisms continuing to survive the cleaning process at an unacceptable rate.

As an industry leader in metal finishing, Able Electropolishing has been recognized and featured in a variety of industry publications. Electropolishing metal finishing is used across many industries including the boatbuilding and marine industry. The advanced process is often used to enhance the surface finish of metal components and assemblies used in marine applications.

Improving the speed, quality, consistency and cost of product manufacturing can be achieved by planning for and implementing an electropolishing process during the manufacturing of parts. The more you know about the process and its benefits, the more you’ll appreciate the logic of incorporating electropolishing into the basic design of your production.

Sometimes referred to as a “reverse plating” process, electropolishing uses an electrolytic chemical bath to remove a uniform layer of surface material. It is well recognized for the beautiful, bright polish it leaves on metal surfaces, and it provides other vital benefits as well. Using no abrasives or part-to-part contact, it is as highly effective on small, complex, fragile parts as well as larger parts. The most definitive way to tell if electropolishing will produce an optimal finish on your part that meets all of your requirements is to submit a sample for testing.

Springs and other automotive parts that must flex and torque undergo tremendous stresses during stamping or forming, creating defects that must be addressed before final use. Even the smallest imperfection creates a weak point in the part that, if not treated, can grow with use as the part flexes and bends – a phenomenon known as the notch effect. Placing stress on notch defects can cause part failure.

Compliance with sanitation and hygiene regulations is of primary concern in the food and beverage processing and packaging industries. Over the years, a number of stainless steel surface finishing treatments have been developed, and each has been used more or less successfully for different types of applications. After years of testing the various surface finishing treatments for resistance to bacteria build-up, electropolishing has clear advantages.

Corrosion can be simply defined as a gradual degradation of a metal surface. It is a natural process that occurs as the result of the chemical and/or electrochemical reaction the metal has with its environment. Unfortunately, it is inevitable; it is only the rate of corrosion than can be altered by various processing and/or finishing methods.

On May 14th, 2018, Able Electropolishing, the world’s largest electropolishing specialist, broke ground on an expansion of their processing production facility. The construction project, expected to be completed in August of 2018, will effectively increase production capacity to Able Electropolishing’s current facility, located in Chicago, employing 200 people on three shifts.

Any metal that will be exposed to a chemically unstable environment, which includes the vast majority of metal parts, is at risk for corrosion if not correctly treated. Although passivation used to be the gold standard for improving corrosion resistance in stainless steel parts, more and more manufacturers are shifting to electropolishing as a versatile and effective finishing option.

A smooth surface on all metal equipment used in the processing of meat and poultry products makes it harder for pathogens to take hold, so finishing processes are always of great concern. Electropolishing metal parts can be an integral part of a multifaceted approach to improving sanitation and preventing foodborne illnesses.

When it comes to engine components and other metal parts for on-highway trucks and heavy-duty construction vehicles, long term part performance is crucial. Passivation and electropolishing are two finishing processes that are commonly used to lengthen the lifespan and improve the performance of metal parts used in heavy-duty vehicles, but how can you determine which finishing technique is best for your parts?

In 2013, FDA enacted a measure that requires most medical devices manufactured in the United States to carry a unique device identifier (UDI). This rule is intended to improve patient safety and increase accountability for manufacturers of medical devices in case of an adverse event. Laser marking is an effective and biocompatible method to keep manufacturers fully compliant with these new labeling requirements.

When a medication is contaminated with microorganisms like bacteria or fungus, the consequences can range from harmless to fatal. For nonsterile drugs taken orally, the effects may be less likely to be dire, as our gastrointestinal tracts provide a highly acidic, unhospitable environment that can kill most microorganisms. However, medications that are administered intravenously or in the form of eye drops, must be completely sterile. Any contaminant can find its way directly into the bloodstream, causing sepsis or even death.

Electropolishing is often the last step to finishing metal parts after manufacturing, and has numerous benefits that improve the parts’ performance and increase life span. Electropolishing is a “reverse plating” process, removing the outer skin of metal instead of depositing metal on the surface. To accomplish this, a metal part is positively charged and submerged in a chemical bath. Then, current is applied to activate the process. The electric current along with the electrolyte pull metal ions off the surface of the part, leaving a smooth, shiny surface behind.

If the passivation process is performed incorrectly, parts may become more susceptible to corrosion rather than less. This makes it imperative that the right passivation process is used in treating specific alloys. But how do you know if your stainless-steel parts are passive, a requirement automakers put on suppliers, and will stand up to industry standards and requirements?

The medical device industry faces multiple challenges when it comes to manufacturing reliable, hygienic, and compliant parts and devices, remarks Tom Glass, president of Able Electropolishing (Chicago). Thus, medical device manufacturers should perform a range of finishing operations to ensure optimal performance. Here’s what Glass has to say about the importance of metal finishing in the medical device industry.

By incorporating the benefits of passivation with surface finish improvement and micro-deburring, electropolishing has become the finish of choice for metal components used in medical devices. This “reverse plating” operation does more than just provide an aesthetic benefit; it provides many functional benefits such as improved corrosion resistance, improved microinch finish, deburring, as well as improved fatigue life. Experienced design engineers anticipate adding the electropolishing operation during the design and prototyping stages. Sometimes though, the finishing operation is an afterthought only added when the product fails to function as designed, often delaying a product’s launch.

The importance of hygiene applies to every aspect of patient care – from the sanitary environment where patient treatment takes place to the range of medical devices used in treatment. The quality of materials and equipment used in treatment can also improve patient outcome. For implants, dental care, and medical devices, a smooth surface with fewer burrs reduces the number of surfaces where contaminants can cling, accumulate, and flourish.
