Since 1990, Ningbo Changfeng Mechanical Factory has specialized in precision stainless steel prototyping for global clients across North America, Europe, Asia, and beyond. Our integrated 5-axis CNC machining and EDM services deliver complex, high-tolerance prototypes with accelerated turnaround – transforming your concepts into functional parts within days, not weeks.
With over three decades of manufacturing expertise and US$10-50 million annual export volume, we provide engineered solutions that bridge design validation and production readiness. The synergy between our advanced 5-axis capabilities and electrical discharge machining ensures exceptional dimensional accuracy even for geometrically intricate components.
| Parameter | 5-Axis CNC | EDM |
|---|---|---|
| Positioning Accuracy | ±0.005mm | ±0.003mm |
| Suitable Material Hardness | Up to 45 HRC | Up to 65 HRC |
| Minimum Feature Size | 0.5mm | 0.1mm |
Key Technical Advantages:
- Simultaneous 5-axis machining eliminates multiple setups, reducing cumulative error by 60-70%
- EDM technology handles hardened stainless steels impossible for conventional cutting
- Integrated workflow from CAD model to finished part in one facility
Our dual-process approach provides tangible client benefits: 30-50% faster iteration cycles for product development, reduced scrap rates through precision machining, and cost efficiency from single-source service execution. Complex internal geometries, thin-wall structures, and micro-features are reliably produced with surface finishes meeting Ra 0.4μm specifications.
Serving diverse markets from medical device manufacturers to aerospace suppliers, our Zhejiang-based facility combines three decades of manufacturing excellence with modern capabilities. With consistent export operations across 15 global regions including Oceania, Africa, and Eastern Europe, we've delivered over 50,000 precision prototypes since 2010. Contact us today for a DFM analysis – leverage our technical expertise to accelerate your product launch timeline while maintaining uncompromised quality standards.
