POWDER MOLDING METHOD

摘要

A powder molding method capable of increasing the orientationality of a molded body (39), comprising the steps of filling powder for magnet manufactured by a quenching method into a cavity (28) formed in a through-hole (24) of a die (16), and applying an orienting magnetostatic field to the powder inside the cavity (28) by a magnetic field generating device (40) while vibrating a lower punch (26) in the through-hole (24) in pressing direction by a vibrating device (30) to pressingly mold the powder inside the cavity (28) by an upper punch (34) and the lower punch (26) so as to provide the molded body (39), the pressing direction being vertical to the magnetic field orienting direction, or being allowed to be parallel with the magnetic field orienting direction.
