Bonded Nd-Fe-B magnet is a kind of magnet made by “pressing” or “injection molding” by mixing rapid quenching NdFeB magnetic powder and binder. The size precision of bonded magnet is very high, and it can be made into magnetic element device with relatively complex shape. It has the characteristics of one-time molding and multi-pole orientation, and can be injected into one with other supporting parts during molding.
