a method of manufacturing the molded hub of a print wheel of the type having a central axial passage of precise diameter and a plurality of elastically deformable , concentrically arranged character carrying radial arms . a metal ring carrying radial passageways is centered in the mold cavity used for forming the hub , etc ., and a plastics composition is injected into the mold cavity only through the center of the ring and by way of the radial passageways whereby the metal ring becomes a unitary permanent part of the hub and defines the central axial passage . after the molding , the molded structure is released from the mold and the remainent central plastic plug easily is sheared from the ring , as by punching , for example . remainent plastic material left within the radial passageways functions supplementary to maintain the stability and concentricity of the ring and hub assembly .
