摘要:
A mold for a golf ball can include a pair of mold halves. Each mold half can have a cavity face including a plurality of pimples. The cavity face can have a low-latitude zone and a high-latitude zone. The low-latitude zone can include a low-latitude base surface having an inner diameter larger than that of a phantom sphere of a cavity. The high-latitude zone can include a high-latitude base surface having an inner diameter equal to that of the phantom sphere. Each pimple can protrude from the low-latitude base surface or the high-latitude base surface. A pimple that intersects an equator plane of the phantom sphere or is proximal to the equator plane can protrude partially or entirely from the low-latitude base surface.
