METHOD FOR PRODUCING SINTERED POWDER MOLDING, SINTERED POWDER MOLDING, METHOD FOR PRODUCING INJECTION POWDER MOLDING, INJECTION POWDER MOLDING AND DIE FOR INJECTION POWDER MOLDING

摘要

A method for producing a sintered powder molding comprising a step for forming a molding for sintering material by injecting a sintering material containing powder capable of sintering and a binder removable in degeasing step into a die provided with a sintering material molding section, and a step for forming an additional molding part by injecting an additional molding material varying into a shape removable or separable from the molding for sintering material into a die provided with and additional molding part in the degreasing step or sintering step, whereby the molding of sintering material and the additional molding part are molded integrally in the die. Since the additional molding part is molded integrally with the molding of sintering material, damage can be prevented at the time of mold releasing and handling of an injection molding is facilitated.
