Abstract

Procedimiento para el moldeo en caliente de artículos (L) realizados en material termoplástico, que comprende las siguientes etapas: - calentar por lo menos una placa de material termoplástico (L) hasta alcanzar una temperatura de plastificación; - comprimir dicha placa calentada (L) entre dos superficies de moldeo (14, 16), enfrentadas una a la otra, de un par de semimoldes (10, 12); y - formar por lo menos un componente (22) fijado a una superficie de la placa (L) mediante la inyección de material plástico a presión elevada en un asiento (18) que comunica con una de dichas superficies de moldeo (14, 16) mientras que la placa está siendo comprimida entre dichas superficies de moldeo (14, 16), caracterizado porque se prevé en dicho asiento (18) una porción estrecha (36) diseñada para reducir la presión del material plástico inyectado en contacto con la placa (L).
