Method of producing a powder sintered formed form, a method for producing a sintered material compact, sintered material compact and powder injection mold apparatus

摘要

PROBLEM TO BE SOLVED: To provide a method of producing a powder sintered compact with which a fine structure of high precision formed of metal or ceramic can extremely easily be formed.;SOLUTION: The method includes a sacrificial die part forming stage where a sheet-shaped or planar sacrificial member 3 changing into a removable or separable form from a sintering material compact in a degreasing stage or a sintering stage is provided with a sacrificial die part 6 composing a part or the whole of a sintering material compacting die part. A sintering material 16 is injected into the die device including the sacrificial die part to form the sintering material compact integrated with the sacrificial member. Further, in the degreasing stage or sintering stage, the sacrificial member is removed or separated from the sintering material compact.;COPYRIGHT: (C)2005,JPO&NCIPI
