ABSTRACT:
A method of making die castings of one metal with a row of spaced fingers of another metal mounts the fingers in slots of an elongated holder with portions of the fingers projecting beyond the holder. The holder is mounted in a die casting machine having a molding cavity surrounding the projecting portions of the fingers. Metal is die cast around the projecting portions of the fingers to form a frame. The casting and the holder are ejected from the die casting machine, and the holder is stripped from the fingers. The method is especially useful for making relays for teleprinters and the like where electrical input produces mechanical movement and where the fingers become cores of electromagnets with the die casting metal being non-magnetic.
