Abstract: A method for manufacturing hemispherical shells for covering a golf ball core, which comprises: mixing a quantity of balata sufficient to form a desired number of hemispherical shells configured and adapted for covering golf ball cores; transferring a predetermined quantity of the mixed balata to an extruder and extruding a plurality of strands of the balata at a temperature of between about 140 DEG and 280 DEG F; cutting the strands into pellets of a desired size and injection molding the pellets into a hemispherical shell.

Abstract: The present invention is directed towards a multi-layer golf ball cover formed by a sandwich injection molding process (8), wherein said golf ball cover comprises an inner layer and outer layer therebetween of a second material. The present invention is directed towards a sandwich injection molding process for forming a multi-layer golf ball cover involving the steps of pushing a measured amount of a plasticized first material (11) into one end of an accumulation cylinder (15), pushing a measured amount of a plasticized second material (21) into the opposite end of the accumulation cylinder (15), and injecting both materials in a single plunging step, so that the first material substantially coats the surface of the mold while the second material substantially fills the interior of the first material.
