Abstract
A method and apparatus for forming a sheet of ductile material by superplastic forming is disclosed. The method is directed to first creating a pre-form by mechanical forming in which the pre-form is created with a die and punch. Thereafter the pre-form is subjected to gas pressure in a forming cavity to complete formation of the part. A metallic gasket is provided to ensure that no pressurized gas escapes from the forming cavity.
