Abstract

Se describe un método de moldeo por estiramiento y soplado para producir un recipiente de plástico (1), en el cual una preforma con una parte de cuello de configuración sustancialmente tubular se inserta en una cavidad de molde (20) de una herramienta de moldeo por soplado (21) de un dispositivo de moldeo por estiramiento y soplado, se estira con un mandril de estiramiento, y con la ayuda de un agente de soplado se infla con presión positiva conforme a la cavidad de molde (20), un domo que comprende la parte de cuello del recipiente y que está conectado a una sección de recipiente (2) provista con al menos una estructura (7) sobresaliente o rebajada con relación a una pared de recipiente (3) se separa, y el recipiente de plástico moldeado por estiramiento y soplado (1) se saca del molde. El método de moldeo por estiramiento y soplado se caracteriza en que al menos la sección de recipiente (2) conectada al domo que comprende la al menos una estructura se comprime axial dentro de la cavidad de molde (20) en una extensión predeterminada antes de desmoldar el recipiente de plástico (1).
