Microcomputer Controlled Metallic Material Torsion Testing Machine

Professional torsion test equipment for metallic materials, fasteners, shafts and metal structural components

Product Overview

This microcomputer controlled metallic material torsion testing machine adopts horizontal rigid frame structure, servo drive and closed-loop measurement & control system. It is specially designed for torsion performance testing of various metal materials and finished metal parts. The system can automatically collect torque, torsion angle and deformation data, calculate torsional yield strength, maximum torque, breaking torque, shear modulus and other key mechanical indicators. It supports constant-angle loading, constant-torque holding and torsion-to-fracture test. Equipped with professional measurement and control software, it realizes real-time curve display, data storage, automatic report generation and export. Widely used in metallurgy, machinery manufacturing, automotive, rail transit, aerospace, fastener production and third-party inspection institutions for incoming material inspection, product quality verification, material development and failure analysis.

Applicable International Standards

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

• GB/T 10128 — Metallic materials — Torsion test at ambient temperature
• ISO 7800 — Metallic materials — Torsion test
• ASTM E143 — Standard Test Method for Shear Modulus at Room Temperature
• ASTM A938 — Standard Test Method for Torsion Testing of Wire

Note: Specific compliance depends on model configuration, torque sensor selection and fixture selection. Customized fixtures and test schemes for extra testing standards are available upon request.
