Title (EN) METHOD OF PRODUCING PERMANENT MAGNETS BY POLAR ANISOTROPIC ORIENTATION MOLDING
(FR) PROCEDE DE PRODUCTION D'AIMANTS PERMANENTS PAR MOULAGE A ORIENTATION ANISOTROPE POLAIRE
Abstract:
(EN) A method of producing permanent magnets by polar anisotropic orientation molding in which a material containing a ferromagnetic powder in a plastic binder is molded directly against the plurality of long thin magnetic pole pieces which make up a portion of the mold cavity.
(FR) Procédé de production d'aimants permanents par moulage à orientation anisotrope polaire, consistant à mouler une matière contenant une poudre ferromagnétique dans un liant en plastique directement contre la pluralité de pièces polaires magnétiques longues minces constituant une partie de la cavité du moule.
