Abstract

MOLDE Y PROCEDIMIENTO PARA FABRICAR OBJETOS CON MATERIAS PLASTICAS NO POLARES, EXPANSIONADAS, CON LA AYUDA DE RADIACION UHF. EL MOLDE CONTIENE UNA CAVIDAD DE MOLDEO (1) DE MATERIA POROSA QUE NO ES MONOLITICA SINO CONSTITUIDA POR ZONAS (B) CON FUERZAS CAPILARES ELEVADAS Y POR ZONAS (A) CON FUERZAS CAPILARES REDUCIDAS PARA LOS LIQUIDOS. LA RELACION ENTRE LAS SUPERFICIES DE AMBAS ZONAS (A Y B) ES FUNCION DEL TAMAÑO Y ESPESOR DE LOS OBJETOS A MOLDEAR. EL MOLDE SE PREPARA IMPREGNANDO LA CAVIDAD POROSA DE MOLDEO DE LIQUIDO POLAR PARA RECIBIR LA MATERIA PLASTICA PREEXPANSIONADA QUE HA DE SER SOMETIDA A RADIACION UHF.
