Leather Vamp Flexing Extensibility Testing Machine

The Leather Vamp Flexing Extensibility Testing Machine is a highly specialized and indispensable instrument meticulously designed to determine the propensity for flexible materials, particularly those used in footwear uppers, to crack or otherwise fail at flexing creases. Beyond assessing material integrity, it can also be used to evaluate whether leathers are likely to produce salt spue. This advanced tester precisely simulates the demanding conditions experienced in the vamp part of footwear during walking, providing critical insights into material performance and longevity.

Key Features & Benefits:

Simulates Real-World Walking Conditions: Specifically replicates the stretching, squeezing, and bending forces experienced by the shoe vamp during walking, providing highly relevant and predictive results.

Dual Failure Assessment: Determines both the propensity for cracking/failure at flexing creases and the likelihood of salt spue production in leathers.

Versatile Material Compatibility: Applicable to a broad spectrum of flexible materials used in footwear uppers, including leathers, coated fabrics, and textiles.

Precise & Consistent Flexing: Utilizes a controlled oscillating motion with a fixed stretching distance of (19 ± 0.5) mm and a consistent scaling speed of (300 ± 30) CPM for reproducible testing.

High Throughput: Capable of testing 12 samples simultaneously, significantly increasing testing efficiency and throughput for busy laboratories and production environments.

Standardized Fixture: Features a precise 40° V-shape fixture with a 6.4mm (R) radius, ensuring consistent and compliant sample mounting.

Digital Accuracy: Equipped with a 6-digit LCD digital display counter for accurate tracking of test cycles.

Compact & Efficient Design: With approximate dimensions of (55x35x30) cm and a weight of approx. 60kg, the machine is designed for efficient use of laboratory space.

Power-Off Memory Function: Ensures test progress is saved in case of power interruption, preventing loss of valuable test data.
