摘要

PROBLEM TO BE SOLVED: To provide a die for manufacturing a ring-shape seamless molded article which, even when oxidative deterioration occurs in a release layer of the die, enables only a component of the die in which the oxidative deterioration has occurred to be replaced or enables the release layer of only the component of the above die to be reformed and which therefore is excellent in economic efficiency, to provide manufacturing apparatus for a ring-shape seamless molded article, equipped with the die, and to provide a manufacturing method of a ring-shape seamless molded article using the die.;SOLUTION: The die 1 is used for manufacturing a ring-shape seamless molded article and is formed by applying a resin solution 3 for a molded article onto the release layer 4 disposed on an outer circumferential surface or an inner circumferential surface of the die, wherein a split face 2 is disposed on at least one part in an application area of the resin solution 3. The manufacturing apparatus for ring-shape seamless molded article, equipped with the die is provided. The manufacturing method of ring-shape seamless molded article using the die is also provided.;COPYRIGHT: (C)2009,JPO&INPIT
