Magnetic materials, assemblies and precision metal components for automotive programs—from defined interfaces and validation through repeat production.
Tier 1 Supply to China's New Energy Vehicle Industry
Our established domestic automotive business includes Tier 1 supply to China's new-energy vehicle industry. Magnetic materials, assemblies and metal components are reviewed against the requirements of each program.
Supplier qualification confirms the relevant supplying and producing entities, the actual component scope, applicable quality-system documents and the records available for the project. Group experience does not imply a blanket approval for every product.

Typical Applications
Automotive application areas:
| Application | Typical Material | What Matters |
|---|---|---|
| EPS & steering motors | NdFeB arc segments, high Hc grades | Demag resistance, consistency |
| Seat & mirror actuators | Bonded NdFeB rings | Low cost, quiet operation |
| Wheel speed sensors (ABS) | NdFeB multipole rings | Pole accuracy, temp stability |
| Water / oil pump motors | NdFeB arcs, overmolded rotors | Sealing, corrosion resistance |
| Transmission sensors | SmCo 2:17 | High temp stability |
| EV auxiliary motors | NdFeB rotor assemblies | Torque density, efficiency |
What We Supply to Automotive OEMs
- ✓High-coercivity grades — N38SH–N48SH and HRE-free high-temp grades that resist demagnetization in demanding duty cycles
- ✓Automotive coating systems — Ni-Cu-Ni tested to 1000-hour salt spray; epoxy and zinc options for specific environments
- ✓Overmolded rotors — insert-molded magnet rotors with stainless shafts — sealed, balanced, and ready for automated assembly
- ✓PPAP-style documentation — dimensional reports, material certs, flux and BH-curve data, capability studies on request
- ✓Traceability — lot-level material traceability through the entire production chain
- ✓IATF 16949 management framework — quality management system operated to IATF 16949 alongside ISO 9001 and ISO 14001; certificate record and current status per producing site are confirmed during quotation
Why Automotive OEMs Choose Ningbo Empire
Connect component performance, quality documentation and production cost.
Documentation for Supplier Review
Material certs, PPAP-style submissions, capability data, and full traceability — the paperwork your quality team expects.
Temperature-Verified Designs
BH-curve verification at operating temperature, not just room temperature. Demag margins calculated for worst-case duty.
Cost Engineering
Compare grade and rare-earth-content options against performance requirements, validation costs and annual production volume.
Project Validation References
Temperature, coating tests and quality records apply to specific materials, parts and producing sites. Confirm the test method, conditions and approval scope for your project.
A Defined Route to Production
Requirement review
Confirm drawing revision, functional interfaces, annual demand and the required documentation.
Sample evaluation
Agree sample quantities, test conditions and the customer acceptance process.
Production approval
Align inspection, traceability, change control and project-specific PPAP or FAI requirements.
