A method and system for compression molding a dual core of a golf ball is disclosed. The method may include a first cycle in which a top mold plate, a middle mold plate, and a bottom mold plate may be used to compression mold concave shells. During the first cycle, the top mold plate and the bottom mold plate may be held at a first temperature T1 and the middle mold plate may be held at a second temperature T2. During the first cycle, the mold plates may be pressed together with a first pressure P1 for a first time t1. A second cycle may include compression molding the concave shells about a solid core. During the second cycle, the top mold plate and the bottom mold plate may be held at the first temperature T1 and pressed together with a second pressure P2 for a second time t2.

A high performance golf ball includes a resin inner core, a rubber outer core, and a cover. The resin inner core is made of a blend of highly neutralized polymers and a low flexural modulus ionomer, and may include a blend of different highly neutralized polymers. The inner core and cover layer each has a specified hardness with a hardness relationship. The cover is a single layer ionomer cover, and may be made from a blend of different grades of the ionomer. The ball as a whole has properties to maximize performance and aesthetic properties, such as backspin off the irons, feel, and sound.

A mold for manufacturing hemispherical sections for a golf ball includes a mold plate and a movable insert. The mold plate includes a first surface. The movable insert includes a second surface. The movable insert is connected to the mold plate. The first surface of the mold plate and the second surface of the movable insert may move relative to one another during molding of a hemispherical section for a golf ball.
摘要:
A golf ball having an outer cover layer with a lower flexural modulus than that of an inner core layer and/or an inner cover layer is disclosed. The lower flexural modulus of the outer cover layer may give the golf ball a good feel during short shots and putting. The inner cover layer may have a first flexural modulus and the outer cover layer may have a second flexural modulus. The first flexural modulus may be at least about 10 times greater than the second flexural modulus. The inner core layer may have a third flexural modulus. The third flexural modulus may be at least about 5 times greater than the second flexural modulus.

A golf ball having a cover layer, an outer core layer, and an inner core layer. The inner core layer has a first compression deformation at 24° C. and a second compression deformation at 70° C. The ratio between the second compression deformation and the first compression deformation is between approximately 1.5 and approximately 2.5.

A golf ball having an inner core layer, an outer core layer essentially enclosing the inner core layer, an inner cover layer essentially enclosing the outer core layer, and an outer cover layer essentially enclosing the inner cover layer. The golf ball includes a blend of at least first and second highly neutralized acid polymers, each having a Vicat softening temperature and a specific gravity. The absolute value of the difference between the Vicat softening temperatures is no more than about 15° C. and the absolute value of the difference between the specific gravities is no more than about 0.015. Also, the method of making the blend and the golf ball is disclosed.

This disclosure provides methods for encouraging golfers and other users to use greenhouse gas reducing golf balls. Greenhouse gas reducing golf balls may include carbon dioxide absorbents, in order that the golf ball may reduce atmospheric carbon dioxide levels to aid in alleviating global warming. The methods may include determining a degree of usage of a used greenhouse gas reducing golf ball, and awarding a reward to a user based on the degree of usage. The methods thereby promote the use of certain greenhouse gas reducing golf balls instead of conventional golf balls, and encourages the reuse of those greenhouse gas reducing golf balls.
摘要:
This disclosure provides a golf ball that includes carbon dioxide absorbents in order that the golf ball may reduce atmospheric carbon dioxide levels to aid in alleviating global warming. The golf ball may include an intermediate layer that is substantially impermeable to water, in order to ensure that the golf ball's core is not degraded by water produced by the carbon dioxide absorbance reaction. The chemical absorbents may be encapsulated in microcapsules so that carbon dioxide is not absorbed until the golf ball is used by a golfer.
