Stretch Forming In Sheet Metal

Stretch forming process is a dieless punch system.

Stretch forming in sheet metal.

Stretch forming is the process of forming extrusions and brake metal by the combined application of tensile and bending forces. Stretch forming is performed on a stretch press in which a piece of sheet metal is securely gripped along its edges by gripping jaws. The process involves the use of the whole sheet of material and hydraulic rams are used to force the tool up into the sheet stretching it to shape. The system having set of gripper is used to stretch the sheet metal.

At senior aerospace thermal engineering we have facilities for stretch forming sheet aluminium stainless steel and other aerospace metals for a range of applications. Stretch forming keeps the extrusion under constant tension while wrapping it around a form or die to make parts into simple or complex contoured curves. Stretch forming is performed on a stretch press in which a piece of sheet metal is securely gripped along its edges by gripping jaws. The die is also called as form block or tool.

Stretch forming is a metal forming process in which a piece of sheet metal is stretched and bent simultaneously over a die in order to form large contoured parts. Stretch forming is a forming process that involves metal wherein a piece of metal is stretched and bent. Stretch forming is a metal forming process in which a piece of sheet metal is stretched and bent simultaneously over a die in order to form large contoured parts. The carriage is held together by either a pneumatic force or hydraulic force which also helps stretches the metal sheet.
