What is The De Mattia and Upper Flexing Tester GT-KB08A

ISO132 DeMattia Upper Flexing Tester Clamps the specimen in grip and flex it constantly, then observe the crack degree to realize or compare its flex-endurance after flex durability. The machine is suitable for rubber, leather, synthetic leather, shoe sole and other materials. 

Demattia Flex Test Principle

The eccentric which actuates the reciprocating parts is driven by a constant-speed motor to give5,00 Hz * 0.17 Hz, with sufficient power to flex at least six, and preferably 12, test pieces at one test. Thegrips hold the test pieces firmly without undue compression, and enable individual adjustment to bemade to the test pieces to ensure accurate insertion. It is useful to arrange the test pieces in two equal groups, so that one group is being flexed while theother group is being straightened, thus reducing the vibration in the machine.
