spring , Iran

A spring is a mechanical element that stores and releases mechanical energy, including compression, tension, and torsion types. Wire diameters typically range from 0.2 to 25 mm, and free lengths are designed from 5 to 1000 mm. Coil counts depend on spring type and loading, ranging from 2 to 100. Common materials include chrome steel, stainless steel, copper, brass, and special alloys. Spring stiffness k ranges from 0.5 to 5000 N/mm, and surfaces are coated with nickel, zinc, PTFE, or industrial paint. Springs are designed for over one million load cycles.

The manufacturing process includes precise wire drawing, CNC or machine forming, heat treatment at 200–450°C for stress relief, and accurate straightening. Springs are tested for force, deflection, and torsion. Final steps include corrosion-resistant coating, surface finishing, and quality control with ±1% tolerance. Springs are used in automotive, machinery, medical devices, precision tools, and defense industries, produced according to DIN, ASTM, and ISO standards.You can order and buy spring from Iran by contacting us through whatsaap and email.
