Abstract
EN EL PROCESO DE MOLDEADO CON ESPUMA PERDIDA Y A PRESION CONTROLADA DE PIEZAS METALICAS, SE HACE AUMENTAR INICIALMENTE LA PRESION A UNA VELOCIDAD COMPRENDIDA ENTRE 0.003 Y 0,03 MPA/SEG DURANTE UN PERIODO DE COMO MAXIMO 5 SEGUNDOS A PARTIR DEL PRINCIPIO DE LA SUBIDA DE PRESION Y DESPUES A UNA VELOCIDAD SUPERIOR A LA DEL PRIMER PERIODO DURANTE UN SEGUNDO PERIODO Y ESTO HASTA QUE SE ALCANCE LA PRESION MAXIMA. EL PROCESO PERMITE OBTENER PIEZAS CUYA FORMA CORRESPONDE AL MODELO Y SIN POROSIDADES.
