Abstract
Using a mold having typically two split mold segments which are mated in a separable manner to define a spherical mold cavity therein, a golf ball having a multiplicity of dimples in its surface is molded by feeding a molding material into the mold cavity. The mold is split along a line off a horizontal great circle of the golf ball into two split mold segments having different areas of contact with the ball. The golf ball as molded is always caught and left in the larger mold segment and thus can be easily removed from the mold by a routine operation.
