Standards:

Applications:

(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.

Product Information:

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.

Test Procedures

(1)Secure the test shoes or sole specimens in the designated fixtures.

(2)Set the desired bending angle and flexing speed according to the test standard.

(3)Start the machine and allow the reciprocating bending mechanism to operate for the preset number of cycles.

(4)Monitor the LCD counter to track the number of flexing cycles completed.

(5)Inspect the shoes or soles for signs of cracking or damage after testing.

(6)Record the results for performance evaluation or compliance verification.

Maintenance Information

(1)Clean the machine and fixtures after each test to remove dust or debris.

(2)Check moving parts and lubricate periodically to maintain smooth operation.

(3)Inspect electrical connections and control components regularly.

(4)Store in a dry, stable environment to prevent corrosion.

(5)Handle fixtures and specimens carefully to ensure measurement accuracy.
