Shoe Peeling Strength Tester
1. Product Introduction & Applications
The Shoe Peeling Strength Tester is designed to evaluate the adhesion strength between the sole and upper of finished shoes. The test involves securing the shoe in a last clamp and applying a peeling force via a peeling knife to separate the sole from the upper. The required force is measured and used to calculate the peeling strength based on the knife width.
Applications:
Quality control of footwear adhesion and bonding
Testing finished shoes for durability and structural integrity
Evaluating adhesives and bonding processes in shoe manufacturing
Comparative testing of different shoe materials and constructions
2. Conformity Standards
