Wire Torsion Winding Integrated Testing Machine

Combined test equipment for metallic wire, integrating torsion and winding functions to evaluate ductility and plastic deformation performance

Product Overview

This wire torsion winding integrated testing machine adopts horizontal rigid frame structure, integrating torsion test and winding test into one single unit. It is equipped with servo drive system, precision clamping fixtures and replaceable winding mandrels. The equipment can complete unidirectional torsion, reverse torsion, winding and self-winding tests for various metal wires. It can assess the plastic deformation capacity of wire materials, and detect internal and surface defects such as cracks, inclusions and layering. The built-in measurement control system automatically records torsion cycles, winding cycles and fracture status. It supports touch screen operation and data storage, which simplifies the testing workflow and reduces equipment investment. Widely used in steel wire, copper wire, aluminum alloy wire, alloy wire, cable raw material, spring wire and steel strand industries for incoming inspection, production quality control and material performance research.

Applicable International Standards

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

• ISO 7800 — Metallic materials — Wire — Simple torsion test

• ISO 7802 — Metallic materials — Wire — Wrapping test

• ISO 9649 — Metallic materials — Wire — Reverse torsion test

• ASTM A938 — Standard Test Method for Torsion Testing of Wire

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

Key Features
