Abstract

EL INVENTO TRATA UN PROCESO PARA MOLDAR LAMINAS NO RIGIDAS INYECTANDO UNA MATERIA TERMOPLASTICA, PARA REALIZAR PIEZAS COMPUESTAS. SE COLOCA LA LAMINA EN EL MOLDE; SE INYECTA UNA CANTIDAD DE MATERIA TERMOPLASTICA (2) QUE ES INSUFICIENTE PARA RELLENAR LA TOTALIDAD DE LA CAVIDAD DEL MOLDE PERO SUFICIENTE PARA RECUBRIR EL CONJUNTO DE LA SUPERFICIE INTERNA DEL MOLDE CON UNA CAPA DEL ESPESOR DESEADO; SE INYECTA SIMULTANEA O SUCESIVAMENTE EN LA MATERIA TERMOPLASTICA, AUN, AL MENOS PARCIALMENTE, EN FUSION, UN GAS A PRESION QUE LA RECHAZA SOBRE TODA LA SUPERFICIE DEL MOLDE CREANDO AL MENOS UNA CAVIDAD (3D, 3E) RELLENA DE DICHO GAS,; SE ENFRIA EL MOLDE PARA LLEVAR LA MATERIA TERMOPLASTICA A ESTADO SOLIDO; SE DESCONECTA EL INTERIOR DEL MOLDE DE LA FUENTE DE GAS A PRESION Y SE ABRE DICHO MOLDE PARA LIBERAR LA PIEZA COMPUESTA ASI OBTENIDA.
