Abstract

Procedimiento de fabricación de cuerpos huecos de materia termoplástica que comprende la formación de un producto extruido fundidoel paso de la materia fundida a través de una hilera de calibrado de forma apropiadaseguida de la puesta en forma convencionalcon ayuda de un dispositivo de conformación y/o de sopladocaracterizado porque la materia termoplástica fundida a una temperatura To superior a su temperatura de fusión TFF se refrigera antes de su entrada en la hilera de calibrado a una temperatura T1 comprendida entre TFF y la temperatura de comienzo de cristalización TDC' siendo efectuada la refrigeración de manera homogénea y en condiciones controladascon objeto de que la materia permanezca totalmente exenta de gérmenes cristalinos hasta el dispositivo de conformación o de soplado.
