The metals are steel, magnetic and nonmagnetic stainless steel. The customer needs to know if one or more of the metal laminations are missing from the stack. There are many different combinations that the gaskets are made up of, on the same machine. We are able to offer several detectors . Our solutions.

Foil Package Count Detector
Prime spends most of it’s time in the metal forming & stamping industry scouting for metal thickness problems to solve. But the following note is an application which demonstrates broader capabilities for our products. It was brought to us by a customer in the packaging industry. They needed to monitor the number of aluminum foil packages in two different boxes. Prime's solution.
