FEC provides testing equipment for the rubber industry, including the De Mattia Flex Tester. The Flex Tester is used to test if rubber can withstand continuous flexing without cracking. It comprises grips that hold specimen in two tiers, with one end fixed and the other end reciprocating to simulate flexing and unflexing. A motor drives an eccentric mechanism to generate the reciprocating motion while a counter tracks the number of test cycles completed. FEC also supplies molding dies, jigs, and other accessories used with the Flex Tester.
