Outsole Flex Resistance Tester | Sole Bending Tester China Manufacturer
Sole Flexing Tester is also known as the outsole bending tester, which is a footwear testing device intended to determine the resistance of outsole to continuous flexing at 90° angle with a constant bending rate.
It is widely applicable to a variety of outsoles of footwear. Usually it is used in conjunction with the outsole rigidity tester in the test.
Test Principle
The test piece fastened to the clamps is incised by a cutting tool in the area directly over the center roller when the specimen is in the maximum stretched state. After flexed for specific cycles at a specified speed through a 90-degree angle, the final cut length on the surface of the specimen is measured using a measuring magnifier to compare with the initial cut length before the test to get the cut growth for determining the flexing resistant performance of the test sample.

How to Carry Out the Sole Flexing Test
- Prepare the test sample and mark the point on it for later insertion of a cut.
- Mount the test piece on the clamps when the test instrument is in a neutral bending position.
- Pierce the test piece at the point above the mandrel using a cutting tool when the specimen is at maximum flex position, then measure the initial length of the cut.
- Actuate the bending tester to conduct the test for 30,000 cycles at a constant speed between 135 cycles /min and 150 cycles/min.
- At completion of given cycles, measure the latest length of the cut again and minus the length of the cut before the test to get the cut growth.
The above is just a reference. Please strictly follow the procedure of the applied standard to carry out the test when you get this testing machine.
