Bonded NdFeB magnets are produced by binding rapid-quenching Nd-Fe-B powders which is mixed with plastic resin to form a magnet by compression molding with epoxy and injection molding with nylon. The injection molding has particularly useful feature in molding very complicated shapes and thin walled parts. The compression molded magnets are limited for simple geometries, but they can offer higher magnetic strength than injection molded magnets because of relative high density. Bonded NdFeB have lower energy properties compared with sintered NdFeB. However, it can be produced with high dimension accuracy and shape complexity. Normally, there is no finishing required for bonded NdFeB. In order to prevent corrosion, the magnet surfaces are treated by epoxy coating or nickel plating.
