The GESTER GT-KB06 EN Sole Flexing Tester (Bennewart Flex Tester) is a high-precision lab apparatus designed to measure the flexing resistance and cut growth/crack initiation of shoe soles under continuous cyclic bending. Engineered for compliance with international safety and quality standards including ISO 20344, ISO 17707, DIN 53543, SATRA TM161, it offers multi-station testing (3 or 6 test positions) with touch-screen controls, precise 90° bending angles, and adjustable flex speeds (125–150 cpm). Ideal for shoe manufacturers, quality control labs, and third-party testing agencies evaluating safety footwear and athletic shoe durability.
The GESTER ROSS Flexing Tester GT-KB05A is a precision laboratory test instrument engineered to evaluate the flex fatigue, crack resistance, and growth rate of rubber products, shoe soles, PU, PVC, and TPR foam materials under continuous 90° rectangular bending. Designed in strict compliance with ASTM D1052, SATRA TM60, ISO 5423, and EN ISO 20344, the GT-KB05A features a high-capacity 6-station specimen clamp capable of simultaneously testing up to 12 samples. Built with surface-oxidized aluminum alloy fixtures and a heavy-duty powder-coated steel frame, it ensures smooth, long-term operational stability for footwear QC labs, rubber manufacturers, and third-party testing institutes worldwide.
This Footwear Testing Machine to determine right angle flexing resistance at low temperature for whole sole of rubber, PU, PVC, TPR foam and other materials.
