Longitudinal stiffness detection of hook center

Detection standard

  • Detection specification

The steel hook core is an important component of footwear products, installed between the outsole and insole of the shoe. It is the "backbone" of the shoe, playing a load-bearing and balancing role, determining the stability and comfort of the shoe when worn, especially for mid to high heels. To ensure the quality of steel hook cores, China has formulated the mandatory national standard GB 28011-2011 "Steel Hook Cores for Footwear", which specifies important indicators such as length, stiffness, hardness, bending performance, and fatigue resistance of steel hook cores. The release of 'Shoe Steel Hook Heart' in 2011 has played a positive role in the development of the footwear industry. When inspecting and submitting footwear products for inspection, if the number of samples cannot meet the requirements of this standard, two hooks taken from the same pair of shoes should be used as samples for all items of the hooks. 2 pieces for inspection of marking, appearance, size, and hardness. Afterwards, one hook core was subjected to fatigue resistance testing, and one hook core was subjected to other tests. Determine the various indicators of the hook center based on the measured effective heel height of the shoes
