Liquid motion within and around a submerged part is one of many ways of enhancing both cleaning and rising processes. In an earlier blog, The BIG Four agitation was described as one of the “big four” variables having a major impact on cleaning and rinsing. In simple terms, agitation means moving the processing liquid relative to …
Preceeding blogs have described two ways of reducing the ionic content of water for use in washing and rinsing applications. Although both reduce ionic content, the process commonly called “De-Ionization” uses a treated resin to capture ions while the “Reverse Osmosis” process uses a semi-permeable membrane. Choosing between the two in the design of a cleaning process …
Cleaning, as we’ve all known it for years, is a matter of taking a “dirty” part and making it a “clean” part using whatever means is necessary and feasible. Typically, the cleaning process involves mechanical removal of contaminants or the use of a chemistry to dissolve and dilute the contaminant. In the case of an …
“Vanishing Oils” are often considered as an alternative to more conventional lubricants in light duty stamping and forming operations. The conception is that these formulations actually “vanish” eliminating the need for cleaning once there is no longer a need for lubrication. True, depending on circumstances, they may reduce or eliminate the need for cleaning but in fact, …
Filters used to filter air, water and chemicals in industrial processes can cost thousands of dollars and more. Some filters are intended to be renewable by cleaning. Other filters, even some considered “disposable,” can be recovered for re-use using ultrasonic cleaning techniques. A filter, as we discussed in earlier blogs (search “filter”) is a device …
This blog is in response to recently received reader questions regarding the best designs for baskets and fixtures used in ultrasonic cleaning applications. The blog Reader Questions – Baskets for Ultrasonic Cleaning addressed previous questions. Today’s question concerns the use of metallic fasteners in the construction of baskets and fixtures to hold parts for ultrasonic cleaning. The …
Some means of reducing water hardness as we’ve described in preceding blogs is an almost universal first step in making water pure enough for most cleaning applications. But water softening only addresses the removal of only a few of many contaminants that are commonly present in our water supplies. The remaining contaminants range from ions …
The preceding blog described the benefit of part agitation in a cleaning process. But, it is not always possible to provide adequate part agitation with a simple agitation of the part parallel to its central axis. With a little creativity, it is possible to provide effective agitation of even very long parts. In fact, there …
Inadequate or improper agitation of parts in a cleaning tank is a common problem in industrial cleaning. Agitation, if properly applied, can be a very powerful aid to cleaning. The result of improperly applied agitation, however, can range from disappointing to disaster. The basic reason to agitate a part in a cleaning tank is to provide or …
I’ve been “playing” with ultrasonics for over two-thirds of my life now and am absolutely convinced that there is still more to know about the technology than anyone knows. The “fish tank” in the lab continues to reveal more questions than answers when it comes to this complex technology. The Ultrasonic Fish Tank in the Lab Still, …
