PROCESS FOR MANUFACTURING THERMOPLASTIC COMPONENTS FOR GOLF BALLS

摘要

The present invention describes an injection molding process for manufacturing golf balls using thermoplastic materials. The injection mold is provided with a heating source and one or more valve gates. The heating source maintains the temperature of the molten thermoplastic material in the conduits through which it is delivered to the mold cavity, and the valve gate shuts off the flow of molten thermoplastic material to the mold cavity. Advantageously, this process reduces or eliminates "trim" or waste material, and thus also minimizes the necessity to recycle thermoplastic material.
