Torsion Testing Machine | Torque Tester | Torque Testing Machine

Universal servo torsion test bench, suitable for torsional mechanical property test of metals, plastics, rubber, fasteners, shafts and finished components

Product Overview

This torsion testing machine, also known as torque tester or torque testing machine, adopts high-precision servo torsion drive and closed-loop control system. It is widely applicable to metal, polymer materials, wire, bolts, shafts, rubber and plastic parts and other specimens. It supports static torsion damage test, torsional stiffness test, tightening torque test, torque holding test and cyclic torsion test. The equipment can automatically record torque-angle curve, calculate torsional shear modulus, yield torque, breaking torque and torsional stiffness. Various interchangeable fixtures are optional to meet different specimen clamping requirements and guarantee high coaxiality during loading. The supporting test software collects torque and angle data in real time, supports curve analysis, batch data storage and standardized report export. It is widely used for incoming inspection, material research, process verification and new product development in manufacturing enterprises and laboratories.

Applicable International Standards

The system is designed to comply with the following recognized testing standards:

• ISO 18338:2021 — Metallic materials — Torsion test at room temperature
