Our Compression Spring Production Process
At Nanpi Haokai, we follow a meticulous production process to ensure every compression spring meets our high standards:
1. Material Selection
The foundation of quality compression springs lies in material selection. We work with various spring steel grades including music wire, stainless steel, and chrome silicon, selecting based on your application’s requirements for corrosion resistance, temperature tolerance, and fatigue life. For specialized applications, we also offer non-metallic options.
2. Precision Manufacturing
Our state-of-the-art CNC coil machines produce compression springs with consistent pitch, diameter, and active coils. For complex shapes or tight tolerances, we employ advanced wire forming technology. All springs undergo strict dimensional checks during production to maintain consistency across batches.
3. Heat Treatment & Surface Finishing
To enhance spring performance and durability, we implement appropriate heat treatment processes based on material type and application requirements. Surface finishes range from standard shot peening to specialized coatings like zinc plating, black oxide, or passivation for corrosion protection.
4. Quality Inspection
Every compression spring undergoes comprehensive testing including load testing, fatigue analysis, and dimensional verification before packaging. Our quality assurance system ensures compliance with both international standards and your specific requirements.
| Production Stage | Key Processes | Quality Control |
|---|---|---|
| Material Prep | Wire straightening, cutting | Material certification verification |
| Coiling | CNC precision coiling | Diameter, pitch measurement |
| End Grinding | Square, closed, or ground ends | End flatness inspection |
| Heat Treatment | Stress relieving, shot peening | Hardness testing |
| Surface Finish | Plating, coating, passivation | Corrosion resistance testing |
| Final Inspection | Load testing, fatigue analysis | 100% dimensional check |
