Leather seam fatigue strength tester is a test equipment independently developed and produced by our company qisnun Precision Electromechanical Technology Co., Ltd. This is a cost-effective and comprehensive after-sales service. It is used to rate the seam strength of the materials used in the surface of the car seat. Seam fatigue device caused by the increase of external force on the sewn part of the seat due to vibration and other reasons while driving the car.

Main parameters:

1. Number of test groups: 2 or 4 groups;

2. Reciprocating speed: 30 times/ min;

3. Test stroke: 150mm;

4. Test load: 29.4N/3kg.

Applicable standards:

JASOM403, GMW3405, GM standard, Ford standard, Honda standard, Mazda standard, Nissan Standard, GB/T4043-2010

Principle of the test:

Specimen specificationn is 10 cm wide and 10 cm long. Band. The surfaces of the two samples overlap, and 10mm from one side is used to sew a test piece with a seam interval of 20±2 stitches/100mm, then install it on the left and right bindings of the test machine and perform 2500 times of load Repeated round-trip test of 29.4N (3kg) and speed of 30 round-trip/min. After the test, the fatigue resistance of the gasket is evaluated and judged by measuring the size of the small hole in the gasket of the specimen due to reasons such as slip under load.
