Abstract

EL INVENTO PERFECCIONA UN PROCEDIMIENTO DE FABRICACION DE PIEZAS DE FORMA U OBJETOS PARA VEHICULOS, EN EL CUAL SE UTILIZA UNA LAMINA DE PLASTICO FUNDIDO QUE SALE DE UNA EXTRUSORA DE RANURA ANCHA O DE SEMEJANTE DISPOSITIVO PLASTIFICADOR, PARA LA FUNDICION EN UN MOLDE NEGATIVO. EL LADO DE LA LAMINA DE PLASTICO QUE ESTA ALEJADO DEL MOLDE NEGATIVO DE EMBUTICION PROFUNDA SE REFRIGERA ANTERIORMENTE, DE MODO QUE, INMEDIATAMENTE DESPUES DE SALIR DE LA EXTRUSORA, ESA SUPERFICIE QUEDA CUBIERTA DE UNA PELICULA DE FUNDICION AUTOPORTANTE. ENTRE LA TEMPERATURA DE LA LAMINA DE PLASTICO Y LA TEMPERATURA DEL MAS FRIO MOLDE NEGATIVO DE EMBUTICION PROFUNDA SE AJUSTA UNA DIFERENCIA DE MAS DE 30 K. LA LAMINA SE CONDUCE POR UNA HERRAMIENTA DE DOS O MAS PIEZAS, DONDE SE SUJETA Y/O CIERRA Y CORTA Y, MEDIANTE EL MOLDE NEGATIVO DE EMBUTICION PROFUNDA Y UNA DIFERENCIA DE PRESION, ADOPTA LA FORMA DEL MOLDE NEGATIVO CON DECORACION DE LA SUPERFICIE Y/O CON UNA ESTRUCTURA MICROPOROSA O GOFRADA, REFRIGERANDOSE O REFRIGERANDOSE POR CHOQUE INMEDIATAMENTE POR MAS DE 70 K.
