We are making some parts that have holes small & deep enough that our plater had to modify their clear alodine process. (Ø.028" x .745" deep with a .015" air bleed toward one end.) They can't etch the parts. If they do, we end up with nasty hard white buildup in the holes that scrap the parts.
So we need to up our game as far as cleaning these parts prior to plating. We did some testing with a shitty harbor freight ultrasonic cleaner to test the theory, and tried straight water, simple green, windex and dawn additives and the straight water did just as well as the rest after plating, so that's the obvious choice. Our coolant washes off pretty easily, but these parts are delicate and I do NOT want anyone trying to mechanically clean them in any way. They are just going to ruin the parts. Also, this job is supposed to run in to 2024 uninterrupted, so the less handling, the better.
I envision putting the parts in a room temp water rinse straight out of the machine (as we already do), then measure, then in to the ultrasonic cleaner with straight hot water for a cycle. This would happen every 14 minutes, 8 hours per day.
Any machine recommendations? I'll be buying new, and I want to buy quality. The tank can be as small as about 4" x 6" and maybe 2" deep. See picture for part size, max two parts per cycle.
Any other recommendations on this process?
