摘要： Golf balls are disclosed that include a centerline axis; an aperture located within the centerline axis; and a kinetic projectile located within the aperture. The kinetic projectile may consist of a hammer actuated .22 caliber single shot load or .27 caliber single shot load. The aperture may, optionally, further include an amount of black powder disposed therein. The golf balls are configured to launch farther and/or produce a striking sound greater than conventional golf balls—when the balls are struck on the backside of the kinetic projectile disposed within the aperture of the golf balls.

摘要： An object of the present disclosure is to provide a golf ball having excellent durability and flight distance and good shot feeling for an average golfer who hits a golf ball at a slow head speed. The present disclosure provides a golf ball comprising a spherical core and at least two cover layers covering the spherical core, wherein a difference between a core surface crosslinking density and a core center crosslinking density is more than 1.0×102 mol/m3 and less than 9.0×102 mol/m3, a hardness difference between a core surface hardness Cs (Shore C hardness) and a core center hardness Co (Shore C hardness) is 13.0 or more and 30.0 or less, a compression deformation amount of the core when applying a load from an initial load of 98 N to a final load of 1275 N to the core is 3.8 mm or more, and the at least two cover layers include a first cover layer and a second cover layer positioned closer to the spherical core than the first cover layer, an average hardness Dave=(Ti×Hi+To×Ho)/(Ti+To) of the first cover layer and the second cover layer is 55 or more, where To (mm) is a thickness of the first cover layer, Ho (Shore D) is a slab hardness of the first cover layer, Ti (mm) is a thickness of the second cover layer, and Hi (Shore D) is a slab hardness of the second cover layer.

摘要： The present disclosure relates to a golf ball, wherein dimples having an extraordinary flight performance by combining the advantages of both circular dimples and polygonal dimples in the related art, in other words, by arranging the combined dimples that give depth to the face of the combined polygon and circle of the same center on the surface of the sphere, the trajectory is bent due to the influence of wind, which is a disadvantage of the conventional polygonal dimples. It is excellent in flight straightness by eliminating the effect, and when flying after hitting, the vertex region, which acts as a small bluff body, rotates and breaks the pressure in advance, causing a quick turbulent transition, and it becomes like an arc of a circular dimple instead of the sides of the general polygonal dimples.

摘要： A method for manufacturing a golf ball having a non-uniform dot pattern is provided. Firstly, a semi-finished product of a golf ball is provided, which includes a ball body and a base layer covering an outer surface of the ball body. After that, the semi-finished product of the golf ball is rotated at a predetermined rotation speed, and a color paint is applied to the semi-finished product of the golf ball in a spraying manner from each of an upper position and a lower position.

摘要： It has been found that carboxylic acid functionalized high cis-1,4-polybutadiene rubber which is comprised of polybutadiene rubber chains having a cis-1,4-microstructure content of at least 90 percent has much better interaction with metal salts of α,β-ethylenically unsaturated carboxylic acids, such as zinc diacrylate or zinc dimethacrylate. This results in such rubber compositions being stiff while still exhibiting a lower level of hysteresis. These characteristics are beneficial when used in manufacturing tire apex compositions, in manufacturing golf ball cores, and in a wide variety of other applications. Such rubber compositions can be used as substitutes for thermoplastic elastomers in many applications.
