Also known as the lost-wax method, this casting technique enables the development of very close tolerances. A wax mold is coated with ceramic, and after the ceramic is hardened, the wax is melted and flows out, leaving a cavity to be filled with molten metal.
a. centrifugal casting
b. die casting
c. permanent casting
d. investment casting
