Abstract: A method for manufacturing a railcar coupler knuckle includes providing a cope mold portion and a drag mold portion. The cope and drag mold portions have internal walls defining at least in part perimeter boundaries of a coupler knuckle mold cavity. The method includes positioning one or two internal cores within either the cope mold portion or the drag mold portion. The one or two internal cores are configured to define a kidney cavity, a finger cavity and a pivot pin cavity of a coupler knuckle. The method includes closing the cope and drag mold portions with the one or two internal cores therebetween and at least partially filling the mold cavity with a molten alloy, the molten alloy solidifying after filling to form the coupler knuckle.
