In a recent blog, I touched on the fact that there is a limit to how long a cleaning solution will continue to produce clean parts as it becomes increasingly contaminated from use. Chemistry and disposing of spent chemistry are both expensive. Changing a bath usually results in a gap in production as the tank(s) …
When particles are the enemy, my general rule is filter, filter, filter! The cost of filtration is small compared to the overall benefit even if it is only “insurance.” There is, of course, the initial cost of installation (filter housings, pumps, plumbing, etc.) but the cost after that is going to be pretty much fixed provided …
A few years ago I wrote a post about the possible perils of automated valves. The thrust of the post was that many automated valves rely on significant line pressure to hold the valve tightly closed. In applications where there is only gravity pressure, as in drain lines for example, valves that are perfectly effective under high …
What happens when parts exit the cleaning process dirty? First of all, PANIC, especially in the case of critical cleaning for optics, semiconductor, disc drive and other industries where particles that can’t even be seen with a microscope render product worthless and unrecoverable! Then there is the inevitable quest for, “Why this is happening?” Although this scenario is …
The applications for wire seem limitless. Wire is used for electrical conductors as well as in structural applications including suspension bridges and other architectural creations. There are about 1 ½ miles of wire in a typical car today and often over 150 miles in a jetliner. A cruise ship? Somewhere around 3,000 miles! Wire diameters …
The cost of acquiring and disposing of cleaning chemistry is usually a major contributor to the overall cost of an industrial or precision cleaning process. Removing contaminants from cleaning solutions can potentially extend their useful life and reduce overall cleaning costs. Traditional filters including those of the bag and cartridge variety are commonly used to remove solid (particulate) contaminants …
