Abstract
Un procedimiento para construir una parte metálica o una mitad de molde metálica completamente densas, para coincidir con otra mitad de molde y formar un molde para fundición de múltiples partes. Las etapas incluyen colocar un patrón con superficies de patrón críticas en una caja que tenga un extremo abierto. Las superficies de patrón críticas miran hacia arriba. Otras etapas implican cubrir las superficies de patrón críticas con una solución de gel reversible de calor concentrado añadidas a la caja, y enfriar la solución de gel para formar un molde de gel sólido elástico. Las etapas adicionales incluyen retirar la caja y el patrón del molde de gel elástico, y fundir un molde cerámico alrededor del molde de gel sólido. En otras etapas, el molde de gel es licuado para la retirada desde el molde cerámico, y el molde cerámico es invertido de manera que sus superficies cerámicas críticas miran hacia arriba. Todavía otras etapas implican cubrir las superficies cerámicas críticas con un polvo, ycolocar una cantidad de un material de infiltración sobre el polvo, y colocar el molde cerámico, el polvo y el material de infiltración en un horno a un temperatura suficiente para fundir el material de infiltración, sin fundir y sin sinterizar el polvo. La cantidad de material de infiltración es suficiente para llenar huecos entre las partículas, generando, por lo tanto, una mitad de molde completamente densa.
