Neodymium magnet manufacturing process steps
Let's review the processing steps. The production of neodymium magnets relies on advanced materials engineering and processes. Here are the main steps:
Process steps:
1. Rare earth minerals are discovered and mined.
2. The ore is processed and refined
3. Elements that make rare earth alloys are added to refined metals
4. Melting (raw material) and strip casting
5. Hydrogen explosion
6. Jet Milling
7. Squeeze under external magnetic field
8. Cold isostatic pressing
9. Sintering
10. Annealing
11. Machining and grinding
12. Plating/Coating
13. Magnetization
14. Packaging and Shipping
