I should have given more information in my last post. The customer slides our product into a slot on a trough which metal flows down. They feel that too much warping/bowing will create stress on the filter which could result in breakage when the metal flows through it. What if I made an adjustable "toaster" gauge? I could determine the average thickness for a production run, set the thickness of the gauge to the average thickness plus 1.5mm, and slide the parts through? Since the average thickness of a production run does not vary by more than .25mm, this should eliminate the majority of the warped parts. It would not be perfect but it would improve what the customer is seeing now.

It seems to me that there must be a physical limit to the "slot on a trough" as you described. If you "determine the average thickness for a production run, set the thickness of the gauge to the average thickness plus 1.5mm, and slide the parts through?" you would not be constrained by a constant limit for warp... imagine a plate folded over on itself... is that too much?
I think that the adjustable parallel plate "toaster gage" may be a good natural choice for process control as stijloor said... but I think that it (or another attribute gage) should have a fixed upper limit for maximum permissable thickness due to size and warp.
