摘要：An improved method of making a ceramic mold having a cavity in which a cast product is accurately formed includes reinforcing relatively flexible wax pattern material having a configuration which corresponds to the configuration of the mold cavity. Supporting the flexible pattern material with a relatively rigid reinforcing member prevents the pattern material from deflecting during removal from the injection die, pattern storage, pattern and gating asmbly and dipping of the pattern in liquid ceramic mold material. Between dipping steps, portions of a wet ceramic coating are wiped away in areas between portions of the wet coating which will eventually form mold ctions. After the ceramic mold material on the pattern has been dried, the pattern material is destroyed by heating or other methods. The resulting mold ctions are then parated and the rigid reinforcing member removed from between the mold ctions. The parate mold ctions are interconnected to form a cavity in which a cast product is accurately formed. In one specific ca, a plurality of mold ctions were interconnected to form a circular mold cavity for a turbine engine components.
