摘要:
A method for manufacturing a gasket that is reinforced by a metal band, which is completely encapsulated within the elastomeric material of the gasket. The metal band is formed with spaced-apart dimples stamped into its inner surface, causing raised projections to form on the outer surface of the metal band. When the metal band is placed in a mold, the raised projections on its outer surface cause the metal band to be spaced apart from the inner wall of the mold. Elastomeric material is then injected into the mold and is able to completely encapsulate the metal band. The gasket is cured and then removed from the mold.

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.

A mold for forming a golf ball makes it possible to form minute dimples, and to improve mold release properties of the mold and wettability of the mold by a material when a urethane material is used for a cover layer. A mold according to the present invention is a mold for forming a urethane cover as an outermost layer of a golf ball, and includes: at least two split molds that are separably joined with each other, and that includes a cavity formed therein by the joining, the cavity being for forming the urethane cover; protrusions that are formed on a cavity surface of the split molds to form dimples of the golf ball; and a composite plating film that covers the cavity surface of the split molds, that comes into contact with a material of the urethane cover, and that contains a nickel-based matrix and fluororesin particles dispersed in the nickel-based matrix.
