Shoe Upper Leather Stretch Testing Machine
Product use
The Shoe Upper Leather Stretch Testing Machine is designed to precisely determine the elongation and tensile properties of shoe upper leather, synthetic leather, fabric, and other flexible materials used in footwear manufacturing. This equipment applies controlled tension to test specimens, measuring key parameters such as tensile strength, elongation at break, and permanent deformation to ensure material durability and compliance with international footwear standards.
Featuring a stable mechanical structure, accurate load cell, and digital display for real-time data, the machine offers easy operation and reliable test results. It is widely applied in shoe material laboratories, quality control departments, and leather product inspection centers. With adjustable test speed and stroke, it fully meets various test requirements for shoe upper materials, helping manufacturers improve product quality and reduce defective rates.

Working Principle of Shoe Upper Leather Stretch Tester
The Shoe Upper Leather Stretch Tester operates on the principle of constant-speed stretching and precise force-elongation measurement. The machine clamps the shoe upper leather, synthetic leather or fabric specimen firmly between two sets of grips. During testing, one grip remains fixed while the other moves at a preset, constant speed, applying axial tensile force to the sample.

Main Structure and Components of Shoe Upper Leather Stretch Testing Machine
The shoe upper leather stretch testing machine mainly consists of a stable machine frame, precision driving system, clamping device, high-precision load cell, displacement sensor, control system and display unit. The rigid frame ensures stability during stretching. The driving system provides stable and adjustable test speed. The upper and lower clamps firmly hold the specimen to avoid slipping. The load cell accurately captures real-time tensile force, while the displacement sensor records elongation data synchronously.
