METHOD FOR MASS-PRODUCING METALLIC PARTS BY METAL POWDER INJECTION MOLDING TECHNOLOGY

摘要

PROBLEM TO BE SOLVED: To provide a method for mass-producing metallic parts by a metal powder injection molding technology by which the metallic parts having desired shape can be manufactured by preventing a fault occurring at the time of degreasing and sintering an injection molding body of metal powder.;SOLUTION: This method comprises: an injection molding process which forms metal powder injection molding; a tool arranging process which arranges the metal powder injection moldings on a degreasing and sintering tool 3; a degreasing process which heats a metal powder injection moldings and removes a binder and forms a degreased body; a sintering process which heats the degreased body to a sintering temperature in a solid phase and forms the metal parts 2; and a metallic part removing process which removes the metallic parts 2 from the degreasing and sintering tool 3. The degreasing and sintering tool 3 oomprises: a stand member 5 which is composed of a column part 52 and a pedestal part 51 which have a slope 53; and a molding arranging member 4 in which a bottom surface freely attachable/detachable to/from the top end part of the column part 52 has a parallel recessed part 41 and the metal powder injection moldings are arranged.;COPYRIGHT: (C)2004,JPO
