For deep-drawing, there are two versions based on tensile-compressive forming according to DIN 8584. Either a piece of cut steel is made into a hollow part that is open at the side - or a produced hollow part is made into one with a low cross-section without deliberately changing the sheet thickness.
Ultimately, deep-drawing is the most significant sheet-forming process. It is used both for mass production and for small batches. Rigid tools are typically used which are employed using presses. The power required for forming is guided to the surface of the deep-drawn part using a punch. Radial tensile stress and the tangential compression stress caused by this lead to the working piece being formed while preventing sheet thickening. Hydromechanical deep-drawing with pressure-regulated water cushions is a modification of the classic methods. Combined approaches - such as deep-drawing in conjunction with stretch forming - such as for vehicle bodywork parts, complement the technology. In any case, Steel is a highly prized partner for the production of deep-drawn parts for a wide range of applications.
