ABSTRACT:
The present invention is directed to improved molded golf ball core constructions and methods for improving the molded golf ball core construction. The molded golf ball comprises a molded spherical core having a soft skin integral therewith, and a cover molded over the core. The soft skin is formed by controlling exothermic molding temperatures. A slug is placed in a mold cavity which is then closed. A steam set point is set, and steam is applied for a 25-30 minute period such that a maximum mold temperature exceeds the steam set point. In the alternative, the core surface may be softened by first immersing a slug in water prior to subjecting the slug to conventional molding conditions. The resulting golf ball comprises a spherical molded core including a central portion having a hardness in a range of about 50-90 Shore C and a surface portion having a hardness in a range of about 50-70 Shore C, the surface portion integral with the central portion and comprising the radially outermost 1/32 inch to 1/4 inch of the spherical core; and a cover molded over the spherical molded core.
