Seam Fatigue Tester
The Seam Fatigue Tester evaluates the fatigue resistance of stitched seams on automotive seat materials, including leather, synthetic leather, and fabric. It simulates repeated stress on seams to assess joint strength, needle hole elongation, and seam durability, helping predict seat service life and guide material improvements.
This two-station benchtop machine allows one or two samples to be tested simultaneously. It features adjustable clamps, programmable cycle counters, and automatic stop for precise and reliable testing.
Applications
Evaluate stitched seams on automotive seat materials
Test fabric, leather, or synthetic leather resistance to fatigue and tearing
Predict seat service life and improve seam design
Conduct quality control and R&D testing for automotive interiors
