Abstract

EL INVENTO ES RELATIVO A UN PROCESO DE MOLDEO CON ESPUMA PERDIDA Y BAJO PRESION DE PIEZAS METALICAS. ESTE PROCESO CONSISTE DESPUES DE HABER RELLENADO EL MOLDE CON EL METAL EN ESTADO LIQUIDO Y ANTES QUE LA FRACCION SOLIDIFICADA DE METAL NO REBASE EL 40% EN PESO, EN APLICAR UNA PRESION GASEOSA ISOSTATICA SOBRE EL CONJUNTO MOLDE METAL CUYO VALOR ESTA COMRPENDIDO ENTRE 1,5 Y 10MPA. EL INVENTO ENCUENTRA SU APLICACION EN LA OBTENCION DE PIEZAS EN PARTICULAR EN ALEACIONES DE ALUMINIO QUE PRESENTAN CARACTERISTICAS MECANICAS MEJORADAS Y EN ESPECIAL UNA MEJOR RESISTENCIA A LA FATIGA.THE INVENTION IS RELATIVE TO A MOLDING PROCESS WITH LOST FOAM AND UNDER PRESSURE OF METAL PIECES. THIS PROCESS CONSISTS AFTER THE MOLD HAS BEEN FILLED WITH THE METAL IN A LIQUID STATE AND BEFORE THE SOLIDIFIED METAL FRACTION DOES NOT EXCEED 40% BY WEIGHT, IN APPLYING A GOSTATIC PRESSURE ISOSTATIC ON THE ASSEMBLED METAL MOLD WHICH IS SHARED IN VALUE AND 10MPA. THE INVENTION FINDS ITS APPLICATION IN OBTAINING PARTS IN PARTICULAR IN ALUMINUM ALLOYS THAT PRESENT IMPROVED MECHANICAL CHARACTERISTICS AND ESPECIALLY A BETTER RESISTANCE TO FATIGUE.
