A
golf ball that is formed by a mold developed from a computerized modeling
system such as CAD or CAE in combination with a CNC
machine tool which superimposes a short waveform, or multiple waveforms, onto a longer base waveform to create a non-planar parting line that is functionally dependent on the underlying
dimple geometry. The non-planar parting line is comprised of a plurality of peaks and valleys that are offset from the
dimple perimeters, as not to bisect any
dimple edge. Also, dimples on one side of the parting line interdigitate with dimples on the other side to form a more uniform distribution of dimples over the entire
golf ball surface. Still further, the non-planar parting line has a amplitude which is less than 0.02 inch from an axis substantially coincident with the
equator of the ball and the length of the parting line is less than 110 percent of the length of a curve defined by the circumference of the
equator. Located at a plurality of sites on the non-planar parting line and offset from the
equator are tabs which are formed on the ball to aid in the finishing operation wherein flash is removed from the ball parting line. The tabs are created by true sprues (vents) and false sprues on the parting surfaces of the ball mold halves.
