dynamic fatigue testing machine
Theseam fatigue testeris designed to evaluate the fatigue resistance of seam on the material which is applied on the surface of automotive seat.The surface material of car seat (leather, synthetic leather, fabric, etc.) is often stitched together.
The stitching strength of the material seam and the fatigue strength of the seam can directly affect the service life of the seat.The strength and life of the joint of the test material can effectively predict the life of the seat and provide the direction of improving the service life.

TestingMethod:
The operator installs the set up gage between one pair of sample clamps on a station. The sewn test sample is aligned and clamped into position.The set up gage is removed and installed on the second station. The second sample is aligned and clamped into position and the set up gage is removed. The desired number of test cycles is entered on the cycle counter and the test is started. Once this cycle count is reached the machine will automatically stop. Test samples are visually evaluated.
