Superplastic Diaphragm Forming (SPDF) is applicable when parts are required to be shaped in materials that are either non-superplastic or where limited strain and near constant thickness are demanded. Unique components made in certain thermoplastic composites can be processed via SPDF and so can heavily perforated superplastic blanks.
