The Coil Spring Manufacturing Process:

1. Material Selection
Common spring materials include stainless steel, carbon steel, 55CrSi, Inconel, etc, These materials are selected for their specific properties.
2. Design and Engineering of Coil Springs
Calculate the spring specifications, using formulas to determine dimensions, load capacities, spring rates, and the spring constant.
3. The Winding Process
It Involves shaping metal wire into the desired coil form. This process requires precision and control to ensure the resulting spring meets all requirements, including diameter, pitch, and the total number of coils.
4. Heat Treatment
Heat treatment modifies the coil spring material’s microstructure and improves its mechanical properties. These enhancements include tensile strength, hardness, durability, and fatigue resistance.
5. Surface Treatment and Finishing
Surface treatments improve aesthetic appearance and significantly extend a spring’s lifespan.
6. Quality Assurance and Testing
