Leather and Shoes Testers

Introduction

The SR-371 Leather Stretch Tester, meticulously designed by Dongguan Sunrise Import & Export Co., Ltd, is an advanced instrument crafted to evaluate the durability of leather and shoe upper materials under simulated walking conditions. Compliant with international standards such as ISO 5423, ISO 4643, SATRA TM25, EN ISO 20344, and GB/T 20991, this tester replicates the stresses of stretching, compression, and bending that shoes endure, assessing materials for scratches, wrinkles, or damage. Perfect for footwear manufacturers, research laboratories, and quality control departments, the SR-371 provides critical insights into material performance, ensuring high-quality shoes that withstand real-world wear. With its power-off memory function, it guarantees seamless testing continuity, making it an essential tool for material selection and product improvement.

Why Choose the SR-371 Leather Stretch Tester?

The SR-371 excels with its ability to test 12 specimens simultaneously, each measuring 64 × 64 mm, at a precise stretch distance of 19 ± 0.5 mm and a speed of 300 ± 30 cpm. Its 6-digit LCD counter tracks cycles with accuracy, while the 40° V-shaped clamps (6.4 mm radius) securely hold samples for consistent results. Compact at 55 × 35 × 30 cm and weighing 60 kg, it fits easily into labs or factories, powered by a 220V, 2A single-phase supply. Built for durability and shipped with professional packaging, the SR-371 comes with lifetime technical support, offering unmatched reliability and value for assessing leather durability and shoe material quality.

How It Works

The SR-371 simulates the mechanical stresses shoes experience during walking by subjecting 64 × 64 mm specimens to controlled stretching, compression, and bending. The process is straightforward:

1. Place the tester on a stable surface in a room-temperature environment.
2. Secure up to 12 specimens in the 40° V-shaped clamps (6.4 mm radius).
3. Set the desired cycle count on the 6-digit LCD counter.
4. Start the machine to initiate stretching at 19 ± 0.5 mm and 300 ± 30 cpm.
5. Inspect samples for scratches, wrinkles, or damage after the test or at intervals.
6. Record results from the LCD counter for quality analysis.

The power-off memory function ensures test settings are retained, even during interruptions, while the intuitive interface makes operation accessible to all users.
