Abstract: The present invention relates to a method for manufacturing a basic metallic frame product used to produce a metallic frame as a part of an electronic product such as a smartphone, a smart key, a remote controller, and the like, and to a metal injection molded system including a metal injection molded product made with a mixture of metal powder and a binder and a support means for fixing the metal injection molded product to prevent the molded side wall from shrinking in the longitudinal direction thereof during a sintering process of the metal injection molded product. As the basic metallic frame product made using the system is provided, the metallic frame may be easily mass-produced, the production cost of the metallic frame may be lowered, and an amount of metal consumed for making the metallic frame may be reduced.

Abstract: Disclosed is a method of manufacturing a heat-resistant component using granules. More particularly, the method of manufacturing a heat-resistant component includes a step of preparing granules by spraying a mixture including a metal powder and a slurry material into a housing equipped with a disc and rotating the disc; a step of preparing a molded object by compression-molding the granules; a step of preparing a sintered object by sintering the molded object at about 1,000° C. to about 1,600° C.; and a step of adjusting dimensions by cutting the sintered object, wherein the housing is sealed and hot air at about 70° C. to about 200° C. is supplied into the housing.

Abstract: The present invention relates to a duplex casting apparatus and a duplex casting method. The duplex casting apparatus includes a casting chamber in which a space portion is formed; an injection tube mounted below the casting chamber and into which a molten metal is injected; a mold detachably connected to the injection tube and having a cavity; a filling medium filled between an inner portion of the casting chamber and the mold; and a pressure regulation means disposed above the casting chamber and decompressing the inner portion of the casting chamber.
