Neodymium magnet production processing
Hydrogen explosion+Jet milling+Sintering+Hypoxia operation process
Sintered NdFeB is the most widely used rare earth/ permanent magnet material. The metallurgy powder was process into micro-powder through special Sintering Craft.
The production process includes formula design, cast string, hydrogen explosion,Jet milling, mixing, molding,Vacuum furnace Sintering , grinding, polishing,
surface treatment(coating), packaging . through the( HD+JM+LOP ）craft ,the neodymium magnet was feature with high coercivity and high working temperature.
