Vertical Torsion Detection Equipment

Vertical structure torsion test instrument for compact parts, screws, bone screws, wire and miniature components torsional performance inspection

Product Overview

This vertical torsion detection equipment adopts vertical frame layout, which saves floor space and is convenient for clamping short samples, fasteners and small finished parts. It is equipped with servo drive system and high-precision torque sensor, supporting closed-loop control of torque and torsion angle. It can complete static torsion, torsion fracture, torsional stiffness, shear modulus and torsional yield test. The vertical structure can be matched with axial tension module to realize combined tension-torsion test as required. It is equipped with professional test software to collect test data in real time, draw torque-angle curves and automatically calculate mechanical parameters. It is widely used in medical implants, precision fasteners, hardware, wire, small plastic and composite parts, suitable for factory quality inspection, university laboratories and third-party testing institutions.

Applicable International Standards

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

• ISO 7800 — Metallic materials — Wire — Simple torsion test
• ISO 18338 — Metallic materials — Torsion test at ambient temperature
• ASTM F543 — Standard Specification and Test Methods for Metallic Medical Bone Screws
• ASTM A938 — Standard Test Method for Torsion Testing of Wire
• ASTM E143 — Standard Test Method for Shear Modulus at Room Temperature

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