ABSTRACT:
A press machine10includes a die12with a through hole12athat defines a cavity, a first press surface14aand a second press surface16afor pressing a magnetic powder18loaded in the cavity, and magnetic field generating means for applying an aligning magnetic field to the magnetic powder18in the cavity. At least one of the first and second press surfaces14aand16ahas a region made of a material having a Vickers hardness that is higher than 200 but equal to or lower than 450. In pressing the powder under the aligning magnetic field, the press machine10minimizes the disturbance in the orientation of the powder.
