A method for manufacturing a metal product by cutting off a removal target part from a metal plate, the metal plate including, prior to processing, an area corresponding to a body which is formed into the metal product by shaping and an area corresponding to the removal target part which is cut and removed from the body by the shaping, the body and the removal target part being indistinguishable in appearance in the metal plate, the method comprising: a beveling step of placing the body so as to be pinched between a pair of plate holding molds having flat shaping surfaces, and in this state, pressing parts corresponding to corners of the body and the removal target part with a pair of round press molds from both sides in a thickness direction of the metal plate, so that the metal plate has the corners of the body which are formed into the beveled surfaces as compressed round surface, and the removal target part, which is crushed, extends from the end surface of the body, wherein each round press mold has a shaping surface including a concavely rounded surface and a flat protruding surface, a crushing step of crushing, after the beveling step, with a pair of finishing press molds instead of the pair of round press molds, the removal target part in the thickness direction of the metal plate by applying, to the removal target part, force from both sides in the thickness direction so as to deform the removal target part into a thin-walled part, wherein the pair of finishing press molds are configured to press the removal target part of the metal plate from both sides in the thickness direction and to enable shear force to be applied to the end surface of the metal plate to form sheared surfaces at an upper part and a lower part of the end surface, wherein the mold adopted in the crushing step includes in addition to the pair of finishing press molds a pair of plate holding molds configured to hold the body by pinching the body from both sides in the thickness direction, and a separation step of separating, after the crushing step, the thin-walled part from the body of the metal plate to obtain the metal product. a beveling step of placing the body so as to be pinched between a pair of plate holding molds having flat shaping surfaces, and in this state, pressing parts corresponding to corners of the body and the removal target part with a pair of round press molds from both sides in a thickness direction of the metal plate, so that the metal plate has the corners of the body which are formed into the beveled surfaces as compressed round surface, and the removal target part, which is crushed, extends from the end surface of the body, wherein each round press mold has a shaping surface including a concavely rounded surface and a flat protruding surface, a crushing step of crushing, after the beveling step, with a pair of finishing press molds instead of the pair of round press molds, the removal target part in the thickness direction of the metal plate by applying, to the removal target part, force from both sides in the thickness direction so as to deform the removal target part into a thin-walled part, wherein the pair of finishing press molds are configured to press the removal target part of the metal plate from both sides in the thickness direction and to enable shear force to be applied to the end surface of the metal plate to form sheared surfaces at an upper part and a lower part of the end surface, wherein the mold adopted in the crushing step includes in addition to the pair of finishing press molds a pair of plate holding molds configured to hold the body by pinching the body from both sides in the thickness direction, and a separation step of separating, after the crushing step, the thin-walled part from the body of the metal plate to obtain the metal product.
