Usage of Superplastic forming in Aerospace Industry

Superplastic forming is an advanced technique used to form metal sheets into extremely high plastic strains in order to create thin-walled pieces that have a close-net shape. The sheet is stretched much more during superplastic forming. You can know more about superplastic forming online via

Superplastic forming is the process of stretching the material by at minimum 200% over the original size, however, the deformation could surpass 1000% in certain metals.

Superplastic forming is utilized in companies in the aerospace sector as a low-cost process for fabricating complex parts into a close-net-shape in a single piece. This can reduce the number of parts that are required and reduce the assembly costs that are frequently associated with manufacturing complex components.

For instance, the single sheet could be shaped into a complicated arrangement of stiffeners, ribs, and skins as an individual piece. Superplastic forming has been credited with the weight and cost savings of nearly all modern airplanes.

Superplastic forming, instead of traditional door panel manufacture, resulted in a weight reduction of 20% and a cost reduction of 40%. The most cost-effective way is usually superplastic forming.

Superplastic forming usually offers an economic advantage when a small to a medium number of complex parts, which are normally manufactured with expensive materials having low formability, is required.
