摘要： A method and system for casting a thermoset layer over a golf ball precursor product is disclosed herein. The system includes multiple stations connected by a conveyor system. The thermoset flowable material is dispensed into a plurality of cavities on each of the mold halves. A plurality of golf ball precursor products are then centered and inserted into the first mold half cavities. The mold halves are mated, heated and cooled. Then, at a de-molding station, the mold halves are separated and the thermoset layered golf balls are removed from the second mold half. A preferred thermoset material is a thermoset polyurethane.

摘要： A method for determining the concentricity of a golf ball having a barium or bismuth doped boundary layer or cover is disclosed herein. The method uses an X-ray imaging machine to determine the thickness of the cover at various locations to ensure concentricity of the golf ball. The boundary layer may be an ionomer blend doped with barium or bismuth in an amount of five to fifteen parts per hundred of the ionomer material, and the cover may be composed of a thermoset polyurethane material. Alternatively, the cover may be doped with barium or bismuth, and the boundary layer may be undoped.

摘要： A golf ball having a cover composed of a polyurethane formed from a p-phenylene diisocyanate (PPDI) based polyurethane prepolymer is disclosed herein. The PPDI-based polyurethane prepolymer is formed from a PPDI and a polyol such as polycaprolactone. The PPDI-based polyurethane prepolymer is cured with a curative such as a 1,4 butane diol and glycol. The PPDI-based polyurethane cover may be either thermoset or thermoplastic. The PPDI-based polyurethane cover has a high flexural modulus at a lower hardness which gives a better feel yet maintains good distance, higher Bashore resilience, higher tensile strength, higher tear resistance, improved elongation, and better playability and control. These benefits and improvements are exhibited even though the cover of the present invention is thinner than those of conventional golf balls. The present invention also provides new golf balls having durable thin covers thereby enabling golf balls with large cores. It is well understood that increasing the core diameter of a golf ball generally translates into an increased COR which in turn generally translates into an increased initial velocity and enhanced overall travel distance.
