Superplastic Diaphragm Forming – A Practical Method for Forming Unique Components
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. This paper illustrates a range of applications for SPDF used at Superform and provides more detailed case studies, some of which involve computer modeling to evaluate and optimize successful outcomes.
