Demesia Zigzag Tester
Category:Flexing & Fatigue Tester
Introduction
The Demesia Zigzag Tester is a professional device used to test the flexural resistance of materials such as rubber, leather, synthetic leather, and shoe soles.
Application
The Demesia Zigzag Tester is primarily used to simulate the repeated bending that materials experience during actual use. Through continuous bending fatigue testing, it observes the degree of cracking in the material to understand or compare its durability. This is crucial for evaluating the fatigue resistance of materials such as rubber and leather, helping manufacturers optimize product design and material selection.
