Does anyone have experience in using external solution vibrators in Wet area Processes? Ultrasonics is out of the question, due to cost. Direct attachment of vibrators to the plating tanks is out of the question, since we are using polypropylene tanks. For the past several weeks I've been evaluating Teflon and some new chemicals by manual vibration (a hammer to the plating racks). I now know this works, but who and where do I get the vibrators from? And what type of cost are we looking at? Can someone advise immediately. I would like to continue my evaluations with automated vibrators.

I use them in most of the key chemical tanks. The manufacturer of the vibrators is VIBCO and they sell for $433.67 in McMaster Carr. Dont get the single speed, get the vibrators with the variable speed. The vaiable speed vibrators allow you to "tune" the vibration frequency to the product in a rack. Once installed, as the frequency is gradually changed you will see the various components of the rack, flight bar and product individually vibrate more aggressively as the respective vibrational frequencies are reached. Just tune the frequency until you reach the desired level of vibration for the component in question. This variation is important because vibration is basically a destructive process that can break welds and unscrew nuts etc., the tuning allows you to zero-in on the target while minimizing future damage to the rest of the line. I also use a spring mounted stainless steel vibration frame suspended over the tanks to maximize the transfer of vibrational energy into the rack and away from the through-hole agitation frame.
