Why Manufacturing in Ningbo?
Ningbo brings together magnetic-material production, specialist process partners and export logistics. This manufacturing network supports:
- ✓Material-sourcing coordination — qualified material sources and supply plans are reviewed for the program
- ✓Regional process coordination — heat treatment, coating and test routes are planned with specialist partners
- ✓Specialist engineering support — magnetic-material, assembly and quality expertise supports production planning
Scaling with You
Prototype and volume requirements are reviewed together so that the production route, quality approvals and delivery plan can support the next stage:
- ✓Controlled production routes — the producing site, process changes and any required requalification are agreed for each program
- ✓Forecast-based stock planning — stock levels and release lead times can be agreed against the forecast and supply arrangement
- ✓Multi-site risk planning — alternative production routes can be reviewed where qualified capacity and customer approval allow
