The GESTER GT-C39A Zipper Fatigue Tester is the industry-standard equipment for determining the reciprocation resistance and long-term durability of slide fasteners. By driving the zipper through continuous back-and-forth cycles under lateral and longitudinal tension, it evaluates physical wear, fluffing, joint displacement, and connector failure. Equipped with an LCD counter and automated machine stop, the GT-C39A provides a highly accurate, cost-effective testing baseline compliant with global standards like BS 3084, EN 16732, ASTM D2061 and SATRA TM50.
Kinetic Energy tester is used to detect the maximum kinetic energy generated by the fired bullets of Projectile toys or the launched bows. It meets standards: ISO 8124-1, GB6675-2, EN-71-1, ASTM F963.
GESTER GT-D06 Gakushin Abrasion Tester is a high-precision laboratory instrument specifically designed to evaluate the resistance of textiles, leather, and printed materials to rubbing. Fully compliant with JIS L0849 Type II and JIS L0823 standards, this machine is the industry standard for the Japanese market and global quality control labs. Featuring a 6-station design, the GT-D06 Gakushin Rubbing Tester allows for simultaneous testing of multiple specimens, significantly increasing laboratory throughput. Its robust construction ensures stable pressure (2kg) and consistent stroke length (120mm), providing repeatable and reliable data for evaluating color transfer and surface wear. Whether for automotive interiors, high-end apparel, or industrial fabrics, the GT-D06 is your essential tool for ensuring color durability and compliance.
The GESTER GT-C39C Zipper Reciprocating Fatigue Tester is a niche, precision-engineered apparatus built exclusively to evaluate the repeated opening and closing resistance of slide fasteners destined for heavy-duty footwear and leather goods. Unlike universal light-textile testers, the GT-C39C is tailored strictly to satisfy the rigorous requirements of the SATRA TM50 Method 1 standard. This dedicated setup simulates the extreme lateral tension, heavy leather stiffness, and high-load mechanical drag experienced by boot and luxury leather zippers, delivering flawless diagnostic benchmarking where standard textile machines fail.
The GT-N16 MIT Type Paper Folding Endurance Tester is used for determining the folding endurance strength of paper and paperboard using hang type weight method.
