Tips for Gasket Inspection

Tips for Gasket Inspection

Tips for Gasket Inspection

(OP)
Does anybody have any good techniques for inspecting some small, flimsy silicone gaskets on a horizontal optical comparator?  The weight of the part deforms itself when 'stuck' on the glass vertically and we would like to find a way to avoid any deformation for a quick and precise inspection.

We are thinking about making a go/no go template (an overlay on the display) for the critical dimensions, but we would like something more concrete for the various radii this part has. Any suggestions are appreciated.

RE: Tips for Gasket Inspection

How about sandwiching the gasket with another layer of a glass or plastic slide and holding it with some adhesive tape or another spring type clamp and then taking the measurements.

We used to check printed circuit boards layout with a plasic film master that is made from a photo sensitive clear plastic. That can have alll the important information inscribed on it - dimensions, drawing number, revision letter, date etc. also. You could employ a similar technique also. You could incorporate go, no-go criteria if you can make colour reproduction with green areas as go and red areas as no-go.
