spring , Iran

A torsion spring is a mechanical element designed to store and release energy through applied 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. Force transmitting legs are designed with lengths from 5 to 300 mm, and surfaces are coated with nickel, zinc, or phosphate for corrosion resistance.

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