Disclosed is a preferred mold design for producing plastic, injection molded preforms, which may be blow-molded into a container of a final, desired shape. A preferred mold (500) includes a combination of hardened material components (530a) and high heat transfer material components (530b) to provide a mold (500) having good wear characteristics, for a sufficiently long useful life, and to enable rapid cooling of the injected preform, in order to reduce the cycle time of an injection and cooling cycle. In some arrangements, the hardened materials may form a portion of the preform cavity thereby slowing the rate of cooling in those areas and inducing a semi-crystalline or crystalline structure in the cooled preform.

L'invention concerne une conception de moule préférée pour produire des préformes moulées par injection, en plastique, qui peuvent être moulées par soufflage en un contenant présentant une forme finale souhaitée. Un moule (500) préféré comprend une combinaison de composants de matières durcies (530a) et des composants de matières de transfert élevé de chaleur (530b) permettant d'obtenir un moule (500) présentant de bonnes caractéristiques d'usure, pour une durée de vie utile suffisamment longue, et permettant le refroidissement rapide de la préforme injectée, de manière à réduire la durée de cycle d'un cycle d'injection et de refroidissement. Dans certains systèmes, les matières durcies peuvent former une partie de la cavité de la préforme, ralentissant ainsi la vitesse de refroidissement dans lesdites zones et induisant une structure semi-cristalline ou cristalline dans la préforme refroidie.
