Abstract (en)
A method of fabricating a nozzle vane comprising a vane portion and axle portions that project out from predetermined end faces of the vane portion, the method including: a first process that molds the axle portions by inserting pre-molding axle portions of a fabricated member having a pre-molding vane portion and pre-molding axle portions with dimensions respectively approximating the vane portion and the axle portions in axle portion molding dies in which a first insertion portion is formed with a shape that projects the axle portions in the axial direction, and pressing the pre-molding axle portions in the axial direction; and a second process that molds the vane portion by inserting the fabricated member after the first process in a vane portion molding die in which a second insertion portion is formed with a shape that projects the nozzle vane in a direction that is approximately perpendicular to the vane surface of the vane portion, and pressing the pre-molding vane portion in directions approximately perpendicular to the vane surface.
