<P>PROBLEM TO BE SOLVED: To provide improvements in golf ball molding processes. <P>SOLUTION: A method of making a golf ball includes: a step for forming a spherical inner core layer; a step for forming two hemispherical shells in a compression mold; and a step for assembling the two hemispherical shells as an outer core layer around the inner core layer. In addition, the method may include a step for curing the two hemispherical shells to form a unitary outer core layer by compression molding the shells around the inner core layer at a temperature that causes the inner core layer to melt. <P>COPYRIGHT: (C)2013,JPO&INPIT |
