I work with many metal finishers that clean the “soft” metals, specifically aluminum and copper alloys. One common, and more recurring issue I see, is staining of these alloys after the forming lubricants are removed in a cleaning step. In the push to go green, many fabricators are switching to water emulsifiable metal working fluids…. Read more »

Cleaning is more than chemistry….. Again
I present to industry on a regular basis, about the importance of “Process over Product” when it comes to getting clean parts in your metal finishing operation. This was reinforced to me more than ever, during an onsite cleaning trial at a new customer this week. In this particular case we are cleaning a critical… Read more »
Explaining the dirty details of better metal cleaning
A conversation with Hubbard-Hall’s Joshua McClellan As a Hubbard-Hall application engineer, Joshua works closely with customers to understand their specific operations and applications of cleaning chemistry to get better results with less chemistry. He has worked with multiple chemical businesses over his career, specializing in chemical application technologies. Download PDF What are the process variables… 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 »

Cleaning High-Value, Complex Parts for Aerospace Applications
Recently, a leading manufacturer of high-value parts for the aerospace industry ran into a cleaning challenge – namely, the cleanliness of parts going through its vacuum brazing process. The existing process was falling short – and experiencing a high field failure rate. Compounding the challenge was a large variation of aluminum alloys and forming processes… Read more »
4 Requirements For A Reliable Rinsing Process
A quick list of the most important factors to bear in mind when determining your rinsing process. Water is becoming an increasingly expensive commodity with even further restrictions in certain areas of the country (pity the poor folks in California). As a result, there has never been a better time to give some thought to… Read more »
