Patent ID: 7713044

Claim:
A molding apparatus for forming a reaction injection molded layer of a ball, the mold apparatus comprising: an assembly; a cavity of the assembly, wherein the cavity of the assembly is defined by a hemispherical first mold surface of the first mold half and a hemispherical second mold surface of the second mold half, each of the hemispherical first mold surface and the hemispherical second mold surface having at least two populations of outwardly extending projections that form a surface of a golf ball, the two populations of outwardly extending projections differing from each other by the height of outwardly extending projections, wherein a first population of outwardly extending projections has a height that extends through a layer of a ball formed in the assembly; a fan gate portion in flow communication with the cavity of the assembly; a connection channel portion in flow communication with the fan gate portion; a turbulence promoting portion in flow communication with the connection channel portion, the turbulence promoting portion having a plurality of convergent portions and a plurality of divergent portions for mixing the reaction injection material; a material flow inlet channel in flow communication with the turbulence promoting portion; and a first source of flowable material and a second source of flowable material both in flow communication with the material flow inlet channel.
