Precision Material Torsion Testing Machine

High accuracy torsion test instrument for small specimens and precision component torsional performance evaluation

Product Overview

This precision material torsion testing machine is developed for micro and small-size specimens, fine wires, tiny shafts, medical parts and miniature structural components. It adopts high-precision torque sensor and servo control system to capture tiny torque and torsion angle changes. It can complete static torsion, torsion breaking test and torsion stiffness measurement, delivering stable and repeatable test data for advanced material research, precision manufacturing quality control and laboratory certification.

Applicable International Standards

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

• ISO 7800 — Metallic materials — Torsion test

• ISO 1432 — Rubber, vulcanized or thermoplastic — Determination of low-temperature stiffening (Gehman test)

• ASTM E143 — Standard Test Method for Shear Modulus at Room Temperature

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

Key Features

• Ultra-high precision torque measurement — Micro torque sensor for low-torque specimen testing.

• High resolution angle acquisition — Captures subtle angular deformation with excellent stability.

• High-response servo control — Smooth loading, low vibration and steady speed regulation.

• Miniature custom fixtures — Suitable for tiny wire, thin rod and small precision parts.

• Real-time curve display — Torque-angle curve automatically generated during testing.

• Multi-protection mechanism — Over-torque, over-angle and overload protection.

• Professional test software — Automatic calculation and multi-format report export.

Technical Specifications

Specifications vary by model configuration and temperature chamber options. Custom torque ranges and miniature fixtures are available for specific precision testing requirements.
