The leather stitching fatigue strength tester is a testing equipment independently developed and produced by our company Qisnun Precision Mechanical and Electrical Technology Co., Ltd. It is cost-effective and has comprehensive after-sales service. It is used to evaluate the strength of seams of materials used on the surface of car seats. It is an ideal tool for evaluating automobiles. This is a seam fatigue device that subjects the sewn part of the seat to increased external forces due to vibration while driving and other reasons.
Main parameters:
1. Number of test groups: 2 or 4 groups;
2. Alternating speed: 30 times/min;
3. Test stroke: 150 mm;
4. Test load: 29.4 N/3 kg.
Applicable standards:
JASOM403, GMW3405, GM standard, Ford standard, Honda standard, Mazda standard, Nissan Standard, GB/T4043-2010
PriTest principle:
The sample specifications are 10cm wide and 10cm high.ng. Take two pieces as a group according to longitude and latitude directions and prepare two pieces. Band. Overlap the surfaces of the two samples and use a sewing machine to sew a test piece with a sewing interval of 20 ± 2 stitches/100 mm starting 10 mm from one side. Then install it on the left and right clamps of the testing machine and perform 2500 charging cycles. Repeated alternating test of 29.4 N (3 kg) and speed of 30 alternating/min. After the test, the fatigue resistance of the joint is evaluated and judged by measuring the size of small holes in the joint of the specimen due to slippage and other reasons under load.
Shanghai Fanbiao Textile Testing Technology Co., Ltd., as an enterprise integrating R&D, manufacturing, sales, training and service, is committed to putting more testing instrumentst into the market and long-term supply of textiles, leather, combustion testing instruments, automobile interior materials, environmental climate aging, masks and protective clothing, etc. can also be customized to meet non-standard requirements. Targeted testing can be carried out according to customer requirements before purchase to ensure that the purchased instruments are suitable.
