The sintered Nd-Fe-B magnets are usually fommed by powder metallurgical processes The general fabricating process routine is as follow:

.Melting--alloying ingot;

.Milling--powders with suitable particle size;

.Pressing--magnetic field oriented green companion;

.Sintering--condensed magnet;

.Annealing--increase coercivity of the magnet

.Magnetic properties testing;

.Grinding for rough magnet profile modification;

.Machining processes such as cutting, drilling or milling to final shape;

.Plating processes such as Ni, Zn, Al, epoxy coating etc;

.Quality inspecting and testing for final products;

. Packing and delivering.
