1. Product introduction

   It is used for the test of torsional properties of metal and non-metal standard specimens and parts, and measures torsional performance parameters such as torsional strength τb, upper yield point τsu, and lower yield point τsl. (For example, equipped with a torsion gauge, it can measure the shear modulus G, specify the non-proportional torsional stress τp, the maximum non-proportional shear strain γp and other parameters).

The testing machine is composed of imported servo motor and drive, torque sensor, clamping system, liquid crystal display measurement and control system, host bench and computer software system.

The clamping method has three-jaw chuck structure, counter-clamp structure, etc., which can be selected from different characteristic materials.
