ISO 17708 Shoes Tensile Strength Testing Machine
1. Product Introduction & Applications
The ISO 17708 Shoes Tensile Strength Testing Machine is designed to evaluate the mechanical performance of footwear and other related materials. It performs standardized tests such as:
Peeling of the upper from the outsole
Separation between composite layers of the sole
Tear or rupture testing of the upper or sole
Tensile, compression, bending, shearing, peeling (90° and 180°), and tearing tests
Applications:
Footwear: Shoes, boots, synthetic leather, upper materials, soles, adhesives
Industrial Materials: Textile, rubber, plastic, adhesive tapes, composite materials, films, electronics, and metal components
Quality Control & R&D: Determining material strength, bond durability, and structural integrity
Machine Highlights:
Touch screen PLC control for intuitive operation
Stepless variable speed from 50–300 mm/min
Compact, workbench-mounted design for convenient use
Real-time display of force and displacement
Automatic data storage, calculation, and printing

4. FAQ
Q1: What types of materials can be tested?
A1: This machine can test footwear materials (upper, sole, adhesives) as well as textile, rubber, plastic, synthetic leather, composite materials, and metal components.
Q2: Can the test speed be customized?
A2: Yes, the standard range is 50–300 mm/min, but special test speeds can be customized per customer requirements.
Q3: How is the force measured?
A3: A high-precision tension and compression load cell records force in real time, with ±1% accuracy.
Q4: Can multiple tests be stored or printed automatically?
A4: Yes, the machine can store results for 10 reference points, calculate averages, grab the maximum value, and print reports via the integrated thermal printer.
Q5: Is the machine safe for operation?
A5: Yes, it includes stroke limiters and overload protection, automatically stopping if the maximum load exceeds 10%.
