    摘要： A multiple layer golf ball having a high compression core and a soft boundary layer is disclosed herein. The multiple layer golf ball may also have a hard cover. The soft boundary layer allows the multiple layer golf ball to mimic the properties of a lower compression core while providing good distance. The multiple layer golf ball has a low driver spin and a high pitching wedge spin. The boundary layer is composed of a polyurethane formed from a PPDI-based prepolymer while the core is composed of a polybutadiene. The cover may be composed of an ionomer blend.

    摘要： An insulated injection molding cavity assembly for molding a thin or low flow material golf ball cover or mantle layer, comprises a cavity for defining a golf ball layer, the golf ball layer comprising a thickness that corresponds to a space defined by the cavity; a metal surface layer surrounding the cavity, and an insulating layer surrounding the metal surface layer. The metal surface layer thickness is decreased and the insulating layer thickness is increased with decreasing golf ball layer thickness.

    摘要： A non-conforming golf ball has a plurality of dimples formed on the outer surface of the ball in a predetermined dimple pattern, the outer surface comprising one or more first areas which include a plurality of first dimples which together have a first dimple volume and at least one second area having a dimple volume less that the first dimple volume, the first and second areas being configured to establish a preferred spin axis. The second area may be a band around the equator which has a lower dimple volume or no dimples, with the polar regions have a higher volume of dimples, creating a preferred spin axis through the poles.
