Abstract
A method of removing or ejecting a part from a first die after the part has been superplastically formed in a cavity of the die at an elevated temperature such that the part sticks to the surfaces of the die. The method includes the steps of forming a flange of the part between opposed die surfaces and providing movable plate within the die cavity and a ring on the opposed surface of the first die that engages the flange and the part in the cavity in a uniform manner. The movable plate and ring are then translated away from the die surfaces to uniformly move the part from the first die after the dies are separated.
