<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a powder compact capable of easily taking out the powder compact rich in three-dimensional design from a pestle. <P>SOLUTION: The manufacturing method manufactures the powder compact. The manufacturing method includes a mortar body 2 having a through opening 21 and an upper pestle 3 and a lower pestle 4 in the through opening 21. The lower pestle 4 has a recess 41 at an upper surface and an opening 42 passing through the recess at the center. The manufacturing method uses a core 5 inserted from the lower side of the opening 42 passing through the recess. The manufacturing method includes: a filling process for filling a raw material; a compacting process for forming the powder compact 10 by allowing the lower pestle 4 and the core 5 to abut on the upper pestle 3; and a discharging process for discharging the powder compact 10 from the through opening 21 of the mortar body 2. In the discharging process, the core 5 is moved upward, and the powder compact 10 is pushed up at the upper surface of the core 5 and is discharged from the mortar body 2. <P>COPYRIGHT: (C)2012,JPO&INPIT |
