Our 70-strong workforce includes 16 technical specialists and 7 senior technicians, ensuring every product meets exacting standards. With over 30 stamping machines ranging from 30-250 tons and 30 CNC processing units, we handle projects of any scale with consistent precision.
Our ISO9001:2015 certification isn’t just a badge – it’s a promise. Every spring component we produce undergoes rigorous quality control at each stage of manufacturing. This dedication to excellence has earned us long-term partnerships with Fortune 500 companies across multiple industries.
Core Product Range: Custom Spring Solutions for Every Application
While we manufacture a comprehensive range of metal components, our spring division specializes in three primary product categories:
1. Compression Springs
Our compression springs feature precise coil spacing and consistent load capacity. Manufactured using high-grade spring steel, these components withstand extreme compression forces while maintaining their shape. Applications include automotive suspensions, industrial machinery, and consumer electronics.
2. Tension Springs
Designed for pulling applications, our tension springs offer excellent elasticity and fatigue resistance. The hook ends are precision-formed to ensure secure attachment points. Common uses include garage doors, agricultural equipment, and medical devices.
3. Torsion Springs
For rotational force applications, our torsion springs provide reliable torque generation. The legs are carefully angled to match specific rotational requirements. These springs power everything from clipboards to automotive components and industrial clamps.
All our springs can be customized in terms of:
- Material selection (stainless steel, carbon steel, alloy steel, etc.)
- Wire diameter and outer diameter specifications
- Coil count and pitch
- End configuration (closed, open, ground)
- Surface treatments (zinc plating, nickel plating, powder coating)
Manufacturing Capabilities: Precision at Scale
What sets Nanpi Haokai apart isn’t just our product range – it’s our manufacturing prowess. Our vertically integrated production facilities allow complete control over every aspect of spring component creation:
| Capability | Details |
|---|---|
| Material Range | Carbon steel, stainless steel, alloy steel, copper alloys, special alloys |
| Wire Diameter | 0.1mm – 20mm |
| Production Volume | Prototypes to millions of pieces |
| Tolerance Levels | ±0.01mm for critical dimensions |
| Lead Time | 7-21 days for standard orders |
Our CNC spring coiling machines represent the pinnacle of precision manufacturing technology. These automated systems produce springs with consistent quality while reducing production times significantly compared to traditional methods. For custom applications, our engineers can develop specialized tooling to create unique spring geometries that meet your exact specifications.
Quality Assurance: Built into Every Component
At Nanpi Haokai, quality isn’t an afterthought – it’s embedded in our manufacturing DNA. Our ISO9001:2015 certified processes include:
- Incoming material inspection with spectrometric analysis
- In-process quality checks at every production stage
- 100% dimensional verification for critical components
- Fatigue testing for high-cycle applications
- Salt spray testing for corrosion resistance validation
- Comprehensive batch traceability
This rigorous approach ensures every spring component we ship meets or exceeds customer expectations. Our quality department maintains detailed records for every production run, enabling rapid resolution of any potential issues and continuous process improvement.
Customization Capabilities: Tailored Spring Solutions
While we maintain an extensive inventory of standard springs, our real strength lies in custom manufacturing. Our engineering team works closely with clients to develop spring components that perfectly match their application requirements:
