Steel Shanks Bending Resistance Tester GT-KB55

Low Temperature Bally Resistance Flexing Tester 20+ years R & D sales experience.

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.

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.

Fibre Board Flex Tester is to determine flex test for shoe insole fiberboard and applicable for common leather shoes and sneaker insole fiberboard.

This Upper Material Flexing Tester is used to determine the propensity for materials to crack or otherwise fail at flexing creases, but can also be used to assess whether leathers are likely to produce salt spue.

Upper DeMattia Flexing Fatigue Tester is to determine bending resistance of rubber, leather, synthetic leather, shoe sole and other materials.

This Upper and Vamp Material Flexing Tester is used to determine the propensity for materials to crack or otherwise fail at flexing creases, but can also be used to assess whether leathers are likely to produce salt spue.
