Abstract

Se proporciona un dado para moldeo por extrusión que produce un tubo que contiene una porción en donde la proporción del área transversal de una capa interior y una capa exterior en la sección transversal axial continuamente varía, en donde la proporción del área transversal puede cambiar en corto tiempo. El dado para moldeo por extrusión 50 mueve un segundo mandril de capa interior 54 en la dirección axial y cambia el volumen del pasaje del fluido del pasaje de flujo de resma de la capa interior 62a de acuerdo con los cambios en la cantidad suministrada de una resma formadora de la capa interior.
