ABSTRACT:
A superplastic forming apparatus is described in which a blank of superplastic material is formed onto a die located in a pressure cavity. The die, which is preferably made of ceramic material, is removable from the cavity and requires no special connections for gas or vacuums ducts and therefore is cheap to manufacture. The use of a separate die also allows accurate monitoring and control of the pressure on the die side of the superplastic blank.
