The Spring Torsion Testing Machine is a specialized device used to evaluate the torsional performance of springs. It measures parameters such as torque, angle of twist, stiffness, and fatigue life under controlled rotational loading, helping engineers assess spring strength, durability, and mechanical behavior for quality control and design verification.
Application
It is used to evaluate the torsional strength, stiffness, and fatigue performance of various types of springs, including coil springs, leaf springs, and custom mechanical springs. It helps in quality control, product development, and ensuring compliance with mechanical and safety standards across automotive, aerospace, and industrial equipment industries.
Performance Features
The spring torsion testing machine is suitable for measuring the torsion angle and torsion torque of various large springs. With appropriate attachments, it can also perform torsional tests on parts and components. This machine complies with the standards JB/T 9370-1999 and JJG 269-2006 for torsion testing machines and material testing methods. Tests can also be conducted according to national and international standards such as ISO, JIS, ASTM, and DIN, providing reliable data. It is ideal for use in industrial and mining enterprises, technical supervision departments, commodity inspection arbitration, research institutes, universities, and quality inspection units.
