A process for producing a coupler knuckle and an improved coupler knuckle design are provided. The process produces a coupler knuckle by constructing a mold having the shape of the coupler knuckle. The mold is coated with a material that is resistant to melting at the molten melt temperatures of the molten metal used to form the knuckle. With the mold coated, the cavities in the mold interior are filled by placing an inert material therein. The molten metal used for forming the knuckle contacts the mold and consumes it, while the coating serves to provide a shape for the knuckle.
