Q
Hi,
My company produces flexible products for autmotive industry like sponge, epdm, felt with severel thicknesses varying between 1mm to 30mm. We are using caliper and thickness measuring device (we call it comparator but i'm not sure it's true). I need some comments on the usefullness of caliper and comparator because sometimes we are suspecting that the original thickness has changed while contacting the meausring device. Is micrometer is a better device to measure flexible products or do you know any other methods or devices? Any contribution is welcomed.

What tolerances are required? How "squishy" is the product? For a product that is very firm, a caliper may be good enough if the tolerance is not exceptionally tight? Do you periodically evaluate the measurements between operators? (gage r&r?) You can find measurement devices ranging from cheap home made go/no-go jigs, right on up through lasers, optical comparators. You need to pick the one that measures what you need, not too precise, not too inaccurate. What is the standard in your industry?
