Title:
GOLF BALL COMPRESSION MOLD
Document Type and Number:
WIPO Patent Application WO2000073034
Kind Code:
A9
Abstract:
The present invention is a method for making a golf ball (10). Two cups are molded from an elastomer separately from a center (12). The cups are molded on both sides of a center mold plate with hemispherical protrusions having a channel circumventing the protrusions to capture excess cup material. The material in the channel aids in centering of the hemispherical cavity and allows the reduction or elimination of reinforcing polymer material. The protrusions force the elastomer cup material into cavities in outer mold plates on either side of the center mold plate, thus forming cups with cavities. The solid or fluid-filled center is placed within the cup cavities, and the cups are joined, preferably by raising the temperature of the mold above the cure activation temperature of the cup material.
