Manufacturing method for magnetic molded body and manufacturing method for anisotropic bond magnet

Abstract

A manufacturing method for a magnetic compact includes a supplying step of supplying a compound containing a magnetic powder, a thermosetting resin, and a wax into a mold, a molding step of forming a compact from the compound and removing the wax from the compact by compressing the compound in the mold while applying a magnetic field to the compound in the mold heated at a molding temperature Tm, a demagnetizing step of demagnetizing the compact after the molding step, and a thermal curing step of heating the compact at a temperature equal to or higher than a thermal curing temperature of the thermosetting resin after the demagnetizing step to obtain a magnetic compact. The magnetic powder contains a Sm—Fe—N based permanent magnet. The molding temperature Tm is equal to or higher than a dropping point of the wax and lower than the thermal curing temperature of the thermosetting resin.
