The Shoe Bending Tester is designed to evaluate the flexing resistance and durability of finished shoes and sole materials. By applying repeated reciprocating bending at fixed angles and frequencies, the tester measures folding performance and monitors crack initiation or growth, providing objective data for quality control and footwear development.
(1)Testing bending resistance of finished shoes, including sports, casual, and work footwear.
(2)Assessment of sole material durability, including rubber, EVA, and synthetic soles.
(3)Quality control in footwear manufacturing to ensure consistent product performance.
(4)Research and development of new footwear designs or sole materials.
(5)Evaluation of aging effects on footwear under repeated flexing conditions.
(6)Applicable in laboratories, footwear factories, and quality inspection agencies.
(1)GB/T 3903.1 — Footwear Flexing Test Method
(2)HG/T 2871-2008 — Finished Shoe Flexing Test Standard
(3)QB/T 4329-2012 — Whole Shoe Bending Resistance Test
(4)EN ISO 20344 — Personal Protective Equipment — Footwear Test Methods
(5)ASTM F1614 — Standard Test Method for Flexing Resistance of Footwear
(1)Reciprocating bending mechanism for repeated flexing of shoes or sole specimens.
(2)Fixtures capable of holding finished shoes or sole materials securely.
(3)Simultaneous testing of one pair of shoes or two sole samples to increase throughput.
(4)Adjustable bending angle from 10° to 50° to control flexing degree.
(5)Variable flexing speed from 5 to 300 cycles per minute for different test protocols.
(6)LCD digital counter to record up to 999,999 flexing cycles.
(7)Robust construction suitable for long-term fatigue testing.
(8)Precision control ensures reproducible and consistent test results.
