Abstract

METODO PARA REGULACION DE LAS CONDICIONES DE UN PROCESO EN UNA HERRAMIENTA DE MOLDEO DESTINADA A LA PRODUCCION DE PRODUCTOS POLIMEROS SINTETICOS O NATURALES, CUYA HERRAMIENTA DE MOLDEO COMPRENDE UNA O MAS PARTES DE MOLDEO HECHAS DE METAL SINTERIZADO CON POROS DE COMUNICACION OBTENIDOS POR PRESION A UNA ALTA PRESION Y SINTERIZADO A UNA ALTA TEMPERATURA DE UN MATERIAL EN POLVO, EN CUYAS PARTES DE MOLDEO O PARTES DE CAVIDAD DE MOLDEO, SE HA HECHO LA CAVIDAD, POR LO QUE LOS POROS ESTAN ABIERTOS HACIA LA CAVIDAD, MIENTRAS LA SUPERFICIE EXTERNA DE CUBIERTA DE LA HERRAMIENTA DE MOLDEO SE IMPERMEABILIZA CONTRA EL GOTEO, EL CUAL COMPRENDE RELLENAR LOS POROS DE COMUNICACION CON UN LIQUIDO CON UNA ALTA TEMPERATURA DE VAPORIZACION Y REGULAR LA PRESION SOBRE EL LIQUIDO EN LOS POROS POR MEDIO DE UN PRODUCTOR DE PRESION CAPAZ DE PRODUCIR PRESION CONECTADO CON LOS POROS DE COMUNICACION EN LA HERRAMIENTA DE MOLDEO.
