Introduction
The seam fatigue tester is used to evaluate the fatigue resistance strength of the seams of automotive seat surface materials. Automotive seat surface materials (such as genuine leather, synthetic leather, fabric, etc.) are mostly of a spliced and sewn structure. The sewing strength of the material seams and the fatigue resistance strength of the seam openings directly affect the service life of the seat. By testing the strength and lifespan of the material seams, the service life of the seat can be effectively predicted and improvement directions for extending the service life can be provided.
Test standards
Toyota TSL 5101G (3.7), GMW 3405, Nissan M-0154, Ford Motor Co. BN 106-02, TSL 5100G Section 4.2
Application fields
The seam fatigue tester is a benchtop model with two working positions, designed to assess the tear resistance or the elongation of seam pinholes of textile or leather seat materials. Each test position is equipped with a pair of corresponding fixtures for sample fixation, and a height gauge is provided to set the separation distance of the fixtures at each test position to 140mm.
Instrument features
1. The mechanical components are made of non-corrosive structural aluminum and stainless steel materials.
2. Durable powder coating and anodized surface treatment;
3. Precision ball and needle bearings;
4. Programmable controller with self-stop function;
5. It can be adjusted by point operation, and the test speed is adjustable.
6. The height of the weight holder is adjustable.
7. The distance between the fixtures is adjustable.
8. The openable and closable protective cover can protect the operator's hands and prevent any danger from contact with the test bench.
Operation Procedure
The operator installs the height setting gauge between the pair of sample fixtures at the testing position. Align the sewn samples and hold them in the corresponding position, then remove the height gauge. Install the second testing position, align the second sample and hold it in position, then remove the height gauge. Input the test cycle number into the counter and start the test. Once the set test cycle is reached, the machine will automatically stop and rely on visual assessment of the test samples.
