sintered neodymium magnet

Generally speaking, neodymium magnets have 2 types of popular production techniques – sintered neodymium magnets and bonded neodymium magnets. The difference between them is mainly in the forming processes.   Bonded neodymium magnets are made by adding neodymium powder to the binder. The bonding process is essentially the same as injection molding.  Meanwhile, sintering is vacuuming …
