The ceramic-mold casting process (also called cope-and-drag investment casting) is
similar to the plaster-mold process, except that it uses refractory mold materials
suitable for high-temperature applications. Typical parts made are impellers, cutters
for machining operations, dies for metalworking, and molds for making plastic and
rubber Components. Parts weighing as much as 700 kg have been cast by this
process.
