Abstract

Se proporciona un método para fabricar un artículo moldeado de espuma, que comprende: un paso de extrusión para extrusionar una resina fundida, amasada que contiene un agente espumante a través de una hendidura anular entre un núcleo de troquel y una cubierta de troquel que rodea el núcleo de troquel para formar un parisón de espuma cilíndrico y extrusionar el parisón de espuma entre un par de moldes divididos; un paso de compresión inferior para comprimir el parisón de espuma entre pinzas inferiores dispuestas bajo los moldes divididos; y un paso de moldeo para moldear el parisón de espuma al cerrar los moldes divididos, después del paso de compresión inferior, en donde H/D es 1.33 a 3.33 y L/D 0.33 a 2.00 en donde D representa un diámetro del núcleo de troquel; H representa una distancia entre una superficie inferior del núcleo de troquel y una superficie superior de cada uno de los moldes divididos; y L representa una distancia entre una superficie inferior de cada uno de los moldes divididos en la superficie superior de la pinza inferior correspondiente.
