Abstract

La presente invención se refiere a un método para elaborar un molde patrón de metal de material termoplástico expandido, que tiene un filtro que comprende un cuerpo de cerámica porosa, en el mismo caracterizado en que el método comprende colocar el filtro en una matriz o molde que tiene una configuración interna que se conforma a la configuración del modelo, de manera que todas las superficies porosas del filtro sean accesibles al material termoplástico cuando el material termoplástico se introduce hacia la matriz o molde, introducir cuentas del material termoplástico hacia el molde o matriz hasta que la matriz o molde se llene y calentar las cuentas de manera de expander y curar las cuentas y formar el modelo.
