It is a process at ambient temperature that modifies a flat metal sheet into a hollow part, adapting it with the press to the shape determined by the die. It is a process of plastic deformation where the metal sheet suffers at the same time a change stretching and shrinking with variations in its thickness.
Sheet metal drawing requires almost exclusively hydraulic presses.
Simple and familiar examples of steel moulded parts are oil sumps, suspension arms, bowls, tanks, fire extinguishers (made welding two moulded parts), kitchen household items…
Sheet metal drawing is the most suitable process for the production using thin sheet of parts with complex surfaces and highly demanding dimensional requirements, replacing successfully parts traditionally manufactured by casting and machining, like sumps and rocker covers. The use of high tensile metal sheet allows as well the production of structural parts of high responsibility and big stresses.
