Composite core die, methods of manufacture thereof and articles manufactured therefrom

A composite core die includes a reusable core die and a disposable core die; where the disposable core die is in physical communication with the reusable core die; and further where surfaces of communication between the disposable core die and the reusable core die serve as barriers to prevent the leakage of a slurry that is disposed in the composite core die.

A method of forming an integral casting core includes adding a disposable insert to a metal core die and disposing a slurry into the metal core die. The slurry includes ceramic particles.
