摘要:
A golf ball having certain relationships and values of its initial velocities at various club head speeds is provided. The golf ball has a typical initial velocity at a low club head speed, but an increased initial velocity at a high club head speed. Therefore, the golf ball may be advantageously used by both amateur golfers having lower swing speeds and professional golfers having high swing speeds. The golf ball may also achieve an initial velocity of at least about 173 mph at a club head speed of about 125 mph, therefore achieving an increased total shot distance.

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 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.

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.

摘要:
A golf ball having a variable initial velocity associated with striking the golf ball with a driver having different head speeds is disclosed. The structure of the disclosed golf ball may cause the golf ball to experience an initial velocity comparable to premium golf balls currently on the market when hit with a driver head speed less than 100 mph. However, the same golf ball may experience an initial velocity higher than premium golf balls currently on the market when hit with a driver head speed higher than 125 mph. As a result, the disclosed golf ball may have different initial velocities associated with different head speeds.
