Contact SupplierDe Mattia Flex Tester, electrically operated with single phase motor provides information about the resistance of vulcanized rubber compounds, coated and treated fabrics to cracking when subject to flexing. Crack development in that part of the surface where stresses are set up during flexing, or if that part of the surface initially containing a crack, causes this crack to extend in the direction perpendicular to stress. This test also assesses the durability of material. The machine tests six specimens at a time. RISHIKESH Flexing Machines is used to test specially moulded samples for resistance to cracking or cut growth by repeated flexing. Flex testing is recommended when the flexing encountered in service is liable to simulate the action of the test. (e.g. tyre sidewalls). Cracking and cut growth increase with increasing cycles. The tester is stopped at intervals specified and the cracks evaluated. Two sets of grips on either side of the frame are reciprocated at constant frequency for a preset number of cycles controlled by a cycle counter. Samples are loaded so that they are flat when the grip are tightened and flexed but not elongated during tester operation.
