Abstract
Se proporciona un método para producir artículos termoplásticos. El método comprende formar una preforma hueca de material termoplástico calentado y colocar la preforma dentro de una cavidad de una herramienta de moldeo, en donde la cavidad define la configuración externa del artículo deseado. A continuación, se aplica presión de fluido a una cámara interna definida por la preforma luego del cierre de la herramienta de moldeo, para expandir la preforma para adaptarse a la cavidad del molde. Después, el artículo formado se somete a una fase de enfriamiento en el molde para reducir la energía térmica del artículo formado lo suficiente como para permitir una expulsión segura con una distorsión reducida. La fase de enfriamiento está definida por un protocolo de enfriamiento variable que aplica uno o más ciclos de choque térmico al artículo formado durante la fase de enfriamiento en el molde.
