The Importance of Bench Testing

Bench testing is not an exact science. Each test can produce slightly different results because every wastewater sample is slightly different. By using bench tests to help determine the best chemicals for the wastewater system, you can eliminate weeks of trial and error on a large scale. You will still need to adjust the wastewater… Read more »

As a Manufacturer, Why Should You Care About Water?

What does Earth Day mean to you? For the metal finishing industry, it means that we continue to make the many parts that make the world go round, from airplane and automobiles to medical devices. If it is metal, we touch it. A side aspect of our industry is that we use millions of gallons… Read more »

Heat Treat Furnaces – Why Parts Cleaning is So Important

When considering proper pre and post cleaning of parts, quality is just one consideration for captive heat treaters and commercial shops. The other is the damage that both vacuum and atmospheric furnaces can incur, leaving shops with costly problems to their equipment including: loss of vacuum, contamination to future runs, smoke bombs and shortened quench… Read more »

5 Steps to Adding Electropolishing

Surveys show that only 25% of all metal finishing operations in North America offer electropolishing to their customers. With a possible rise in the need for electropolishing thanks to reshoring efforts for medical parts and equipment, demand could outpace availability as manufacturers seek to find finishers to electropolish those parts to a high specificity. Fortunately,… Read more »
