Microcomputer Controlled Torsion Testing Machine

Material testing system for measuring the torsional properties of metal, non-metal and composite materials

Analyzing the torsional properties of a wide range of materials, from metals to composites, requires precision and versatility, and this testing machine offers just that. Capable of handling torque up to 5000 N/m, the material testing system features a high-precision digital speed control combined with a precision reducer that drives the ball screw mechanism. With broad speed adjustment capabilities, the testing machine operates with minimal noise, ensuring smooth and stable testing.

Applications
Ideal for testing the torsional properties of metal materials, non-metallic materials, composites, and structural components.
