Patent ID: 8753560

Claim:
A method of manufacturing a golf ball, the method comprising the steps of: providing a golf ball mold comprising: a cavity provided by a pair of mold halves mating at an equator of the mold, a cavity face of each mold half comprising a number of pimples extending into the cavity for forming golf ball dimples, wherein a mating circumferential edge of each mold half is shaped with multiple flat planes lying along a single flat plane, each of the multiple flat planes separated either by a single mold half protrusion extending toward the other mold half or by a mold half recess which receives a single mold half protrusion of the other mold half upon mating the mold halves, and each protrusion comprising part of a pimple, wherein upon mating the mold halves: a proportion P 1 of mold half protrusions arranged next adjacent to a protrusion of the other mold half, with respect to a total number of protrusions of both mold halves, is equal to or greater than 50%, and a proportion P 2 of mold half protrusions arranged next adjacent to a protrusion of both the same mold half and the other mold half, with respect to a total number of protrusions of both mold halves, is equal to or greater than 50%, wherein a proportion Pw of a total sum of protrusion widths along the mold equator, with respect to an entire equator length, is equal to or greater than 46%, and wherein a mold latitude region equal to or less than 20° comprises pimples having different diameters, all of which can be sorted in descending order so as to provide a ratio Dx/Dn of average top 10% diameter Dx with respect to average bottom 10% diameter Dn of equal to or less than 1.15 but larger than 1; placing a golf ball material into the mold cavity; and allowing the material to flow into the mold cavity so as to conform to a golf ball shape having dimples, each dimple having an inverted shape of a corresponding pimple.
