Stretch Forming Process

The stretch forming process is ideal for producing a wide range of parts requiring contour surfaces such as door panels, nose sections, skin sections and wing leading edges, due to lower non-recurring costs associated with the process. The variety of shapes and cross sections that can be stretch formed is almost unlimited. The process involves the sheet material to be held in place and the use of hydraulic rams to force a form tool into the sheet, stretching it to shape.
