ABSTRACT:
A method for producing parts including at least one internal cavity. In the method at least two metal sheets are diffusion bonded; then the bonded metal sheets are bent; and then each of internal cavities is inflated by superplastic forming. The method is carried out by a mold allowing at least one first part to be diffusion bonded and then bent while inflating at least one second part by superplastic forming during a single operation, whereby the mold is heated. The method can be applied, e.g., to the field of aeronautics.
