Abstract

Un método de fabricar artículos de pared delgada de material termoplástico cristalino por termoconformación en una banda u hoja de dicho material termoplástico con reducción del grueso de la banda u hoja, teniendo dicho material termoplástico un margen de temperaturas críticas de fusión cristalina e incluyendo dicho método además un acondicionamiento de temperatura de dicha banda u hoja a condiciones de temperatura adecuadas para termoconformación y corte de dicho banda u hoja de los artículos configurados, caracterizado porque dicho acondicionamiento de temperatura supone establecer en el núcleo interior de dicha banda u hoja una temperatura más alta que el límite superior de dicho margen de temperaturas críticas de fusión cristalina y establecer en las regiones superficiales exteriores de dicha banda u hoja una temperatura inferior al límite inferior de dicha margen de temperaturas críticas de fusión cristalina.
