Shoe Flexing Tester
1. Product Introduction & Applications
The Shoe Flexing Tester is designed to evaluate the durability and folding performance of finished shoes and soles. By subjecting the specimens to long-term, continuous bending at a fixed angle and frequency, the machine simulates real-world walking stresses to assess crack formation or material fatigue.
Applications:
Testing sports shoes, casual shoes, work shoes, and other finished footwear
Evaluating midsole, sole, and complete shoe flexing resistance
Quality control and R&D of footwear durability
Comparative analysis of different sole materials for bending resistance
2. Conformity Standards
HG/T 2871-2008, Method B — Finished footwear flexing test
GB/T 20991-2007 — Flexing resistance of shoes and soles
QB/T 2881-2007 — Finished shoe flexing and fatigue testing
3. Product Advantages
Versatile Testing Capability: Can test both finished shoes and separate sole materials on the same machine.
Measures Key Durability: Evaluates resistance to repeated flexing and potential crack initiation or growth.
Standard Compliant: Designed to meet national standards for footwear and sole flexing tests.
Controllable Test Parameters: Adjustable bending angle and flexing speed ensure precise, repeatable testing.
Quantitative Results: Records the number of flexing cycles performed, enabling cycle-to-failure assessment.
Multiple Testing Stations: Capable of testing up to four specimens simultaneously, improving throughput.
Wide Speed Range: Adjustable speeds accommodate various test methods and material types.
4. Product Features
Reciprocating bending mechanism applies repeated flexing to test specimens.
Interchangeable or adaptable clamps allow testing of both finished shoes and sole materials.
Multiple testing stations: can test 2 pairs of shoes (4 shoes) or 4 sole samples simultaneously.
Adjustable bending angles: 30°, 45°, 60°, 90° for different test requirements.
Adjustable flexing speed: 0–150 ± 5 cycles per minute.
LCD digital counter tracks up to 9,999,999 flexing cycles.
Robust construction suitable for repetitive fatigue testing in laboratory or quality control environments.
Standard Configuration:
One testing machine
Four clamps/palms
One wrench
One power cable
One copy of operating instructions
One delivery note
