Der Hintergrund

Technology, Creativity and Future

For the wide range of STÜKEN parts various methods are used side by side or in combination: deep drawing, stamping and bending metal, the parts are then cleaned, polished and refined in subsequent processes.
The cleanroom production, the assembly of components and different test methods are also everyday business during production. The following pages provide you with a short overview of all our proceedings.

More information

Flitter in stamped-bent products

Flitter arises during the production process, especially when bending coated parts, and causes process disturbances in the subsequent treatment of the products at the customer’s location.
STÜKEN uses a special bending technique to avoid flitter during the production process.

Save material with deep-drawing

Economy begins with the material use. With deep-drawing an economical use of material is guaranteed. With up to 80% material utilization the deep-drawing technology is more resource efficient than the turning technology.

The meaning of deep drawing

Deep drawing is a process of plastically cold deformation of metals. The phenomena of the elastic and plastical deformation are scientifically described with the stress-strain diagram.



What does Stüken mean by "Tetris"?

Tetris is not only the computer game classic at STÜKEN. With "Tetris" we mean the maximum protection against deformations in customized blisters developed by us. Upon customer request, the STÜKEN parts are packaged custom fit.

What is a drawing ratio?

In deep drawing the limits of acceptable form change are defined by the drawing ratio. As a parameter the ratio of the cross sectional area of the finished drawn part is considered to the face of the blank. This determines how many drawing operations for the production of the drawn part are required and assesses the drawability of the body sheets. Furthermore, the correction factor for the pulling force can be determined. (Source: Technicians Forum).

What is actually a secondary process?

Deep drawing and punching are STÜKENs’ core competencies. Assembly capable components often require additional processing. Cleaning and degreasing, deburring, grinding, electro-polishing, electroplating and laser welding - these processes are called secondary processes. Stüken offers many solutions for a turnkey product.
