General Information

The Wallace range of 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.
The range consists of 6 machines capable of handling 12, 24 or 36 samples in either an unheated cabinet or an oven with digital temperature control having a range of 60°C to 150°C. Easy access to the interior of all six machines is provided through side pivoted front and rear doors. Four recessed lamps provide interior illumination and knurled flywheel is used to rotate the mechanism for easy sample loading. The main shaft is fitted with a balance weight to ensure smooth running.
