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. |
