  • Patent number: 11219950
    Abstract: Provided is a method for manufacturing a sintered component having a hole formed therein, in which a sintered component having no defect, such as cracks, can be manufactured with good productivity and also a reduction in tool life accompanied by forming the hole can be suppressed. The method for manufacturing a sintered component includes a molding step of press-molding a raw material powder containing a metal powder and thus fabricating a green body; a drilling step of forming a hole in the green body using a candle-type drill and thus forming a thin-walled portion, of which a thickness Gt as measured between an inner circumferential surface of the hole and an outer surface of the green body is smaller than a diameter Gd of the hole; and a sintering step of sintering the green body after the drilling step.
