Ceramic mold casting, also known ambiguously as ceramic molding, is a group of metal casting processes that use ceramics as the mold material. It is a combination ofplaster mold casting and investment casting. There are two types of ceramic mold casting: the Shaw process and the Unicast process. These casting processes are commonly used to make tooling, especially drop forging dies, but also injection molding dies, die casting dies, stamping dies, andextrusion dies.
