Torsion springs are precision elastic components that store and release energy by withstanding torsional torque via their two end arms, featuring high torque output, compact structure, and excellent fatigue resistance. Our custom torsion springs comply with GB/T 1239.3-2009 standards, using premium materials like stainless steel and carbon steel, supporting full-spec customization from single/double helical structures to micro/heavy-duty. With precise torsional stiffness, stable resilience and long service life, they are widely used in automotive parts, industrial machinery, electronics, furniture hardware, etc. Custom wire diameter, coil count, arm length and surface finishing (zinc plating, shot blasting) are available to meet elastic connection and reset needs under harsh conditions.
