April 3, 2026 – With the increasing demand for high-quality metal wires in industries such as construction, electric power and aerospace, the accuracy and efficiency of wire torsion testing have become crucial. The HST-HEZ-10 Digital Wire Torsion Testing Machine, independently developed by HST Testing&Tester Machine Group, has emerged as a reliable tool for wire torsion tests, helping enterprises and research institutions complete tests efficiently while complying with international standards.
Abstract:
Wire torsion testing is an essential method to evaluate the plastic deformation resistance and internal defects of metal wires. This news introduces the specific operation process of wire torsion test using HST-HEZ-10 Digital Wire Torsion Testing Machine, highlights the machine’s advantages in compliance with standards, high precision and easy operation, and summarizes its application value in ensuring wire quality and promoting industrial upgrading. The machine is suitable for metal wires with a diameter of 3-10mm, covering multiple industries and providing reliable data support for quality control and research.
The operation process of wire torsion test using HST-HEZ-10 is simple and standardized. First, prepare the test wire: select 5 qualified wires without local hard bends, straighten them gently without damaging the surface, and cut them to the required length (original gauge length plus twice the clamping length). Then, adjust the machine: set the gauge length (up to 500mm) according to the wire diameter, adjust the clamping chucks to keep coaxial, and set the torsion speed (15-120r/min) and torsion mode (one-way or two-way) as required.
Next, install the wire specimen, ensure its axis coincides with the chuck axis, and apply a small tensile force (no more than 2% of the wire’s breaking force) to keep it straight. Start the machine, which will automatically twist the specimen and record the torsion number in real time. The test stops when the specimen breaks or reaches the preset torsion number, and the machine automatically holds the torsion data. Finally, check the specimen’s surface defects and record the test results for evaluation.
Key Takeaways:
- The HST-HEZ-10 complies with GB/T 239.1-2012, ISO 7800:2003 and ASTM A938 standards, ensuring the authority of test results.
- It features digital real-time display, adjustable torsion speed (error <±10%) and high-precision chucks (jaw hardness 50-65 HRC), guaranteeing test accuracy.
- The machine is widely used in colleges, scientific research institutions and wire production enterprises, suitable for testing high-speed steel wires, prestressed steel wires and copper alloy wires.
4. Its simple operation and automatic data recording reduce manual errors and improve test efficiency, providing strong support for wire quality control and material research.
