PROBLEM TO BE SOLVED: To control temperature of a mixed material when mixing at least two precursors to cast a golf ball cover. SOLUTION: A casting system for a golf ball cover has a temperature controlled mix head. The mix head is capable of pulling back any excess mixed material without the use of snuff-back valves after discharging the mixed material. Alternatively, or additionally, the mix head is capable of moving in one or more of directions x, y, and z. Furthermore, the system is capable of adjusting the viscosity of the mixed material in the nozzle of the mix head. Additionally, the mix head is connected to a closed-loop flow controller, which supplies precursors and curing agents in an accurate amount. COPYRIGHT: (C)2008,JPO&INPIT
