ABSTRACT:
A method for manufacturing a centrifugal casting die includes the steps of supplying a first liquid agent for forming a backup layer to be releasably bonded to an inner surface of a cylindrical die, rotating the die body so that the first liquid agent is uniformly spread over the entirety of the inner surface of the die body, and curing the first liquid agent spread over the entirety of the inner surface of the die body to form the backup layer. A second liquid agent is applied to be bonded to be integral with an inner surface of the backup layer to form a top layer. Then the die body is rotated so that the second liquid agent is uniformly spread over the entirety of the inner surface of the backup layer and cured to form the top layer. The top layer releasably holds a centrifugally casting material supplied to the inner surface thereof.
