Stamped Parts

With our punching machine we produce different form elements, such as recesses, threads, louvres and beads. We have a wide range of different punching tools in stock to offer you an excellent choice of different sizes and shapes.

Circular blanks

We can punch circular blanks up to a maximum diameter of 70 mm. Larger blanks can be produced by laser cutting. There are many different applications for blanks made of steel and aluminium. Whether as an end piece for a pipe, as a washer for screw connections or as a spacer between two components. They are used in a wide range of applications.

We punch blanks of steel, rustproof steel and aluminium up to a diameter of 70 mm.

Louvres

Louvres are among the form elements that can be produced with a punch. In principle, louvres are narrow, elongated, channel-shaped recesses that are open on one side. They can have several functions, but are mostly used as ventilation slits for heat exchange on casings.

For the production there are own punching tools in different sizes. Through the tool form the material is then bent up to this cut and the louvre is formed. If louvres are required which are longer than the tools, the production must be made by nibbling.

Beads

Beads can also be produced with our punching machine. Beads are elongated recesses which are stamped into the sheet metal parts to increase the stiffness. To maximize this effect, the length and stamping depth of the bead must be adapted to the size and thickness of the workpiece.

It also plays an important role how the bead runs over the workpiece. There is the basic rule of fitting rectangular workpieces with circular beads and vice versa. The stiffening effect is significantly higher if the shape of the bead differs from the basic shape of the plate metal. Furthermore, beads must not cross each other, as the stiffening effect is lost at the crossing point.

As in many cases the beads exceed the length of our tools, they are manufactured by nibbling.

Threads

With our punching machine we are able to produce internal and external threads without chipping. The non-cutting production of internal and external threads is basically identical. In both processes a special tool is pressed into the material. For external threads, material is pressed with great force from the surface of a blank into the crests.

For internal threads, the process is identical, except that the tool penetrates into a pre-drilled hole to form the thread. As there is no loss of material with this process, they are much more durable in use.
