Bonded NdFeB
Bonded Nd-Fe-B magnets are made of rapidly quenched NdFeB magnetic powder and binder through "press molding" or "injection molding". Bonded magnets have very high dimensional accuracy, and can be made into relatively complex magnetic element devices, and have the characteristics of one-time forming, multipole orientation and so on. The injection magnet has high mechanical strength and can be injected with other supporting parts during molding.
