Heavy metals are very common contaminants in industrial waste treatment streams. Due to the fact that many metals are very toxic, they are removed before the waste water is discharged from the facility. The list of most common heavy metal contaminants include lead, copper, chromium, nickel, silver, zinc, mercury, cadmium, and arsenic. The most common way to effectively remove these metals from the waste stream is by precipitating the metal in an insoluble form, such as hydroxides or sulfides. Precipitation by hydroxide formation is the most common method. Many heavy metals are amphoteric, … [Read more...]

What Can I do to Lengthen the Life of my Cleaner Bath?
There are a few things that will affect the life of your cleaner baths. The first is the condition of parts that you are putting into the bath. If they are covered in and dripping with oil/grime, your cleaner isn’t going to last very long as it will have a lot to clean up. This is easily fixed by lowering the amount of oil used to ship or manufacture the parts. Note that this may not be possible if you aren’t in charge of manufacturing the parts. It’s recommended that you discuss this with those who send you the parts to be plated. Additionally, depending on the type of cleaner you are using, … [Read more...]

I Need A Cleaner, What Have You Got?
For such a simple question, why is the answer so complex? It starts with the understanding of what a cleaner is made of. Since we rarely deal with solvent cleaning these days, let’s limit this discussion to aqueous cleaners.

Increase Productivity to Maximize Profitability
It is easy to become complacent as we run our businesses. As many say, “We get stuck inside our comfort zone." To stay competitive, metal finishing operations must continually search for ways to improve their productivity to maximize profits. Acid Zinc Chloride Plating Solutions Many finishing companies operate acid zinc chloride (often called chloride zinc) plating solutions due to the faster plating speed achieved and the ability to plate directly on hardened steel. Yes, alkaline zinc offers you distinct advantages like excellent plate distribution as seen in the old, high cyanide bearing … [Read more...]

The Electroless Nickel Phenomenon
By Doug Trageser In my 30 years of selling in the metal finishing industry, I have seen many changes and improvements to processes that have benefited the companies that sell and apply those processes to finished goods. The process that I believe has improved the most in that time is the electroless nickel (EN) plating process. Early in my career in the mid 1980’s, a handful of plating shops were applying electroless nickel, but they were few and far between. The technology was not as well understood then, as there was not nearly as much published literature on the subject as there is … [Read more...]

I Want a “Cheap” Cleaner
I hear a lot of prospects and customers looking for a "cheap" cleaner. To most people, "cheap" means a low price per unit. Consider these questions and statements when asking for or using a "cheap" cleaner: How effective is it? Perhaps a higher priced cleaner could clean at lower temperatures, shorter times, provide a better surface for coating adhesion, appearance, and corrosion protection. How much are you using? Perhaps a higher priced cleaner would reduce overall maintenance additions and rebuilding costs or perform at a lower, safer concentration. How much sludge is … [Read more...]
