spiral spring , Iran

A torsion spring is a mechanical element that stores and releases energy through torque and angular displacement. Wire diameter typically ranges from 0.2 to 15 mm, and inner coil diameter is designed from 2 to 200 mm. The operating angle can reach 360 degrees or more, and torsional stiffness ranges from 0.5 to 1500 N·m per degree. Common materials include chrome spring steel, stainless steel, and fatigue resistant alloys. Spring legs are designed with lengths from 5 to 300 mm for torque transmission, and surfaces are coated with nickel, zinc, or phosphate for corrosion resistance.

Structurally, torsion springs are manufactured by CNC wire coiling with precise angle control. Stress relief heat treatment at 200 to 400°C reduces internal stresses. Torque and angular deflection tests evaluate mechanical performance with ±1 percent accuracy. Surface finishing and anti wear coatings increase service life. These springs are used in hinges, opening and closing mechanisms, industrial equipment, and precision tools, designed for more than one million operating cycles.You can order and buy spiral spring from Iran by contacting us through whatsaap and email.
