Deep Drawing: high production output at top quality
During deep drawing a sheet metal blank - a blank, sheet or plate – is being shaped by tension-compression forming to a hollow body which is open at one end. This is done in several steps with a number of punches and drawing dies or matrices. The structure of the material is not destroyed in the process but the material properties are rather improved through the deformation.
The deep - draw technology is a qualitatively, economically and environmentally compelling solution. Even the smallest and thinnest parts can be manufactured precisely and the material utilization may be more than 80 percent - while keeping costs and the environmental impact equally low. In addition, deep drawing allows for very high stroke rates; this possibly increases the production rate compared to the metal-cutting process.
For deep drawing STÜKEN also uses transfer presses and progressive dies and with these two methods produces over a thousand different pieces. Suitable materials include steel, copper, nickel and aluminum alloys such as stainless steel and brass as well as special metals such as molybdenum, niobium and titanium.
