Abstract
A method of separating an electroformed metal substrate from a mandrel includes establishing a parting gap between the electroformed metal substrate and the mandrel, attaching the electroformed metal substrate at a parabolic end of the mandrel to a parting fixture, and introducing a fluid through the parting fixture into an opening of the mandrel to effect separation of the electroformed metal substrate from the mandrel. The parting fixture includes a parabolically shaped outer cup with a fluid inlet tube extending through the bottom thereof. The parting fixture also preferably includes an inner cup for containing the fluid introduced through the fluid inlet tube and a vacuum device to effect attachment of the electroformed metal substrate to the parting fixture.
