SATRA TM20 Footwear Shoes Heel Impact Tester is used to determine the impact strength of heels of ladies’ shoes, and the result provides an assessment of the liability to failure under the occasional heavy blows received during wear.
Feature Its principle is, a heel, clamped with the tip uppermost and the stem approximately vertical, is subjected repeatedly to measured blows from a pendulum striker , the energy of the blows increasing successively until the heel fails. While the method is applicable to all types of high heels ,of whatever construction, it is particularly useful for injection molded plastics heels which incorporate a steel dowel reinforcement, giving information on the suitability of the dowel’s hardness or softness.

To indicate impact energy with min sacle 0.5J
Clockwise rotate the fixed screw until the heel can be placed.
Counterclockwise rotate the fixed screw to hold the heel.
Loosen the handle A, adjust angle block to make heel to form 90 degrees with impact head.
Loosen the handle B to make the heel tip is 6±1mm below the impact plate, then lock the handle A and B
