Metal Material Torsion Testing Machine

Precision torsion testing for metallic wires, rods, and structural components

Product Overview

This computer-controlled torsion testing system is engineered for determining the torsional properties of metallic materials under controlled angular displacement. The machine employs a servo motor drive coupled with a high-precision torque transducer, enabling accurate measurement of torque, torsion angle, and torsional stiffness. It is suitable for quality control, material research, and failure analysis in wire, rod, and component testing.

Applicable International Standards

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

• ISO 7800 — Metallic materials — Wire — Simple torsion test
• ISO 9649 — Metallic materials — Wire — Reverse torsion test
• ASTM A938 — Standard Test Method for Torsion Testing of Wire
• GB/T 10128 — Metallic materials — Torsion test at room temperature

Note: Specific compliance depends on model configuration, grip selection, and specimen dimensions. Customized solutions for additional standards are available upon request.
