spring production , Iran

Spring manufacturing is the process of designing, producing, and quality-controlling springs for industrial, automotive, medical, and precision tool applications. Spring types include compression, tension, torsion, flat, and formed springs. Wire diameters range from 0.2 to 25 mm, and free lengths vary from 5 to 1000 mm. Stiffness k is designed from 0.5 to 5000 N/mm or N·m/degree, depending on spring type and dimensions. Common materials include chrome steel, stainless steel, copper, brass, and fatigue-resistant special alloys. Surfaces can be coated with nickel, zinc, PTFE, or industrial paint for corrosion and wear resistance.

The manufacturing process includes precise wire drawing, CNC or machine forming, coiling or bending according to spring type, heat treatment at 200–450°C for stress relief, and final straightening. Springs are tested for load, deflection, angle, or torque using standard testing machines. Final steps include corrosion-resistant coating, surface finishing, and quality control with ±1% tolerance. All processes comply with DIN, ASTM, and ISO standards, and springs are designed for over one million load cycles.You can order and buy spring production from Iran by contacting us through whatsaap and email.
