ABSTRACT:
The present invention provides an improved apparatus and system for mixing castable polyurethanes and polyureas and for prolonging the dispensing time for dispensing them into a golf ball mold for application to a golf ball sub-assembly. A nozzle framework includes support housing heaters and heater adaptors for each dispensing port to delay the onset of drool and improve cut off in the dispensing tubes. The combination of fluorinated dispensing ports, the heating of the polyureas or polyurethanes, and inclusion of a capillary orifice in each dispensing port significantly prolongs the time before the advent of drool is detected.
