6 Station Cold Capable Bally Flex Tester

1. Function and Application

The 6 Station Cold Capable Bally Flex Tester evaluates the flexural fatigue resistance of leather, composites, vinyl, surface finishes, and other materials at temperatures below ambient. Specimens are folded and clamped between fixed lower clamps and oscillating upper clamps. Each cycle flexes a crease in the specimen to simulate real-world material folding, such as the creases that form in shoe uppers during walking.

This tester is specifically designed for use inside environmental chambers, enabling evaluation at temperatures down to -30°C while the control panel remains external for easy operation.
