Stretch forming is widespread in the aerospace industry. It allows the manufacture of large parts, most often made of aluminum, with lower tooling costs than those of the drawing tools, as only a single run is required to form the part, on a single die.

Profile stretch forming is a very repeatable process for profile forming in 2D or 3D with the following advantages:

Elastoforming is an economical and high productivity forming technique to stamp shallow parts. The process uses high pressure to press a blank into a die using flexible, high strength elastomer pads.

Hot Forming is a punch/die forming technique with a short cycle time using medium-high temperature to increase the formability of the material being formed.

Superplastic Forming Process

The superplastic forming (SPF) process has emerged as a reliable method of manufacturing in the aerospace industry. This technology is used for the production of complex aircraft parts.

Linear Friction Welding is a solid state welding at forging temperature. The heat is generated by the friction.
The process is generally divided in 4 phases:
