Finished Shoe Bending Tester: Ensuring Durability and Flexibility
This article presents a specialized bending tester designed to evaluate the flexural durability of finished shoes under controlled conditions. The machine simulates repetitive foot motions to assess material fatigue, structural integrity, and long-term performance, providing critical data for quality control and product optimization.
Applicable Standards
The tester adheres to key international standards including ISO 17707. SATRA TM92. and GB/T 3903.5. ensuring compliance for global footwear markets.
Main Parameters
| Parameter | Specifications |
|---|---|
| Bending Angle | Adjustable ±90° (customizable) |
| Flexing Frequency | 0.5-3 Hz (programmable) |
| Testing Cycles | Up to 500.000 cycles |
| Load Capacity | 50-200 N (adjustable) |
| Data Output | Real-time graphs and cycle counts |
Working Principle
The machine uses a pneumatic or servo-driven actuator to apply cyclic bending forces to shoe soles. Specimens are secured in a clamping fixture, and bending parameters are controlled via an intuitive interface. Sensors monitor torque, angle, and cycle count to detect material degradation.
Test Principle
Dynamic Flexion Simulation: Reciprocal bending mimics walking motions, stressing critical areas like soles, seams, and uppers.
Fatigue Analysis: Continuous cycling identifies crack propagation, delamination, or structural failure points.
Quantitative Reporting: Generates data on stiffness changes, energy loss, and failure thresholds for design improvements.
This tester enables manufacturers to predict field performance, optimize material selection, and enhance product lifespan through rigorous lab testing.
