New Chinese National Standard Shoe Bending Testing Machine

Instrument Introduction:

This machine is specifically designed to test the entire shoe or sole during repeated bending processes. Under repeated tensile stress, deformation and material fatigue may occur due to the stress, resulting in glue separation between the upper and the surrounding strip, upper and outsole, and sole and surrounding strip. Cracks may also appear on the upper, sole, and surrounding strip(Oral) or rupture phenomena.
