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.

An intellectual material object management method includes: an RF scanning device scans a carrier tag of a replenishment carrier and a shelf tag of at least one present supplying shelf among stock shelves of a warehouse to assist for putting the replenishment carrier on a target shelf for the replenishment carrier. An MO picking list for obtaining information of at least one selected MO is received. The RF scanning device scans an MO tag of a present picking MO on a present picking shelf among the stock shelves and a list tag of the MO picking list to assist for obtaining the selected MO from the stock shelves of the warehouse. A remaining amount of remaining MOs is counted. An amount tag for the remaining MOs is printed according to the remaining amount of the remaining MOs for sticking on a remaining MO carrier for loading the remaining MOs.
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.
