Abstract
Se proporciona un método mejorado para la inyeccion de estirado por soplado. en el proceso, una resina fundida es inyectada dentro de una cavidad de inyeccion definida por un molde de inyeccion, un molde de reborde y un nucleo de inyeccion para formar una preforma deseada, donde el tiempo de enfriamiento para esta preforma, es reducido positivamente para formar una capa de película rígida sobre la superficie exterior de la preforma sin aumentar el espesor. Después, es liberada del molde de inyeccion y transferida a un molde de soplado con una porcion de boca que es mantenida con el molde de reborde, aunque la capa de película mantiene la configuracion de preforma y el interior está en un estado de alta temperatura y es moldeado por estirado por soplado en un artículo moldeado hueco, por ejemplo una botella del cual la porcion principal es ultradelgada en el momento cuando la temperatura de la superficie de la preforma, que aumenta debido a su propia temperatura interior, es significativamente mayor que una temperatura de transicion de vidrio (Tg) y se espera que alcance una temperatura máxima. Por lo tanto, es posible permitir el moldeo de un artículo moldeado hueco, que tiene un espesor de 0.17 mm o menor, sin que esté afectado por limitaciones del espesor de la preforma y la temperatura de moldeo, aun en un proceso de moldeo, donde la preforma es liberada del molde a una temperatura elevada y entonces es sometido inmediatamente al molde de estirado por soplado.
