Abstract
The present invention offers a production method for anisotropic resin-bonded magnets with precise dimensions in high productivity. It comprises the aligning step in which the preform is preliminary compression-molded in the preforming molding die 22 in the preforming press 20 with an applied magnetic field to align the magnetization direction of the magnet powder at a temperature in which the thermosetting resin in the compound becomes liquid state, the transferring step in which said preform is transferred from preforming press 20 to densifying molding die 32 in a densifying press 30, and densifying step in which said partly cured preform is compression-molded by applying pressure in a densifying press 30 to obtain desired shape of magnet.
