1. Function and Application
The Cold Pinch Fold Fabric Tester is designed to evaluate the resistance of soft trim materials, fabrics, and leather to cold cracking. It is primarily used in the automotive and materials testing industries to simulate cold environmental conditions and determine how materials withstand repeated folding or pinching stresses at low temperatures.
It is suitable for Chrysler and Toyota testing protocols, ensuring compliance with industry-specific cold flexing requirements.
