  • Method for making a ceramic mold
    Patent number: 5368086
    Abstract: A new method for producing a composite ceramic mold for production of metal castings is disclosed. The composite mold is comprised of a backing layer and a facing layer. The backing layer is formed by pouring a mixture of a suitable refractory, a gelling agent, and a binder about an oversized pattern. After the backing layer hardens, it is fired and then baked. The facing layer is then formed integrally with the backing layer by pouring a mixture of comminuted highly refractory material, a gelling agent, and a binder between the oversized backing layer and a dimensionally-correct pattern. After the facing layer hardens, it is fired and then baked.
