Abstract
Un miembro macho tiene un núcleo cilíndrico con una muneca interna desplazada por presión de aire para abrir un pasaje de aire para aire bajo presión hasta un extremo de la muneca. La cavidad hembra y la muneca forman una pared de fondo de recipiente. Se inyecta un copolímero termoplástico de polietileno en el molde a una temperatura de aproximadamente 243.3 s C, el molde tiene una temperatura superficial de aproximadamente 37.7 - 54.4 s C y el material plástico tiene una temperatura de aproximadamente 54.4 - 71.1s C al momento de la eyección del recipiente del molde. Se forman costillas en el reborde de recipiente que tienen una profundidad tal que provocan que el recipiente se estire en aproximadamente 6 % cuando se remueve del núcleo. Los bordes externos de las costillas son coextensivos con la pared lateral del recipiente. Se forma un labio de enganchamiento de tapa en el borde de reborde de recipiente. El proceso tiene un tiempo de ciclo preferido de 14 segundos y emplea un núcleo sin corriente. La superficie de moldeo se mantiene a la temperatura deseada por medio de un circuito de agua de enfriamiento en el molde.
