Process for production of magnet, magnet obtained thereby and production apparatus for molded articles for magnet

A process for production of a magnet which comprises

• a slurry supplying step in which a slurry containing a magnetic powder and a dispersing medium is supplied into the cavity of a molding apparatus,
• a molding step in which the slurry is subjected to compression molding while applying a magnetic field to the slurry to obtain a molded article and
• a sintering step in which the molded article is sintered to obtain a magnet,
• wherein the molding apparatus comprises a first die having a through-hole into which the slurry is supplied, a slurry supply gate which supplies the slurry being formed in the inner wall surface surrounding the through-hole, a second die inserted in the through-hole and a third die that forms a cavity by sealing the through-hole together with the second die, the slurry being supplied in an amount such that it is less than the volume of the cavity when the second die has been inserted in the through-hole of the first die and has blocked the slurry supply gate, and
• in the molding step, the slurry is compression molded after the second die has blocked the slurry supply gate.
