Sheet metal forming operations produce a wide range of consumer and industrial products, such as metal desks, appliances, aircraft fuselages, car bodies, and kitchen utensils.. Sheet-metal forming also called press working, press forming or stamping, is among the most important of metalworking processes, dating back to as early as 5000 B.C., when household utensils, jewelry, and other objects were made by hammering and stamping metals such as gold, silver, and copper..

Strength and strain hardening are both reduced at higher temperatures. These property changes are important because they result in lower forces and power during forming. In addition, ductility is increased at higher temperatures, which allows greater plastic deformation of the work metal. For these reasons the forming processes can be classified as:. A material is pushed or drawn through a die of the desired cross-section.. Extrusion.  is a process used to create objects of a fixed cross-sectional profile. . Direct Extrusion. Indirect Extrusion.
