ABSTRACT:
A super-plastic forming tool for forming aluminum sheets is provided that includes a seal bead that is configured to facilitate removal of the aluminum sheet from the seal bead after a super-plastic forming operation. Contraction of the aluminum sheet at a faster rate than the super-plastic forming tool facilitates removal of the aluminum sheet due to the specific geometry of the seal bead. The seal bead has a more shallowly sloped outer surface than its inner surface and may be provided in different configurations including flat, convex, concave shapes.
