<p>Disclosed is a preferred mold design for producing plastic, molded preforms, which may be blow-molded into a container of a final, desired shape. A preferred mold includes a temperature control system for maintaining the preform mold at a desired temperature. The temperature control system can pass fluid through channels (302, 330, 403) within the preform mold to cool plastic that is injected into the preform mold. The mold comprises a neck finish mold (402) , the neck finish mold configured to transfer heat away from the molding surface toward a channel (403) conveying a working fluid. A heat transfer member (212) may be at least partially positioned within the channel to transfer heat to the working fluid. In some embodiments, the mold comprises a high heat transfer material .</p> |
