Stamping & transformation

We get your requirements into shape.

Stamping and bending

With its stamping and bending technology, KERN-LIEBERS offers a manufacturing process that includes additional transformative process steps – linear or radial – on a single production machine.

In addition to the stamping and bending process itself, the additional operations we can offer include

  • Laser welding
  • Resistance welding
  • Riveting
  • Caulking
  • Pressing
  • Clipping
  • Clinching
  • Wobble riveting
  • Embossing

Other process steps such as washing, 100% quality inspection, labeling, oiling and packaging can be implemented to customer specification using fully automated all-in systems.


  • Support during definition of the design
  • B-sample production with close-to-production processes and auxiliary tools in a short time
  • Tool design and manufacture
  • High volume production, including fully automatic downstream testing

Our range

  • Width: Up to 150 mm
  • Thickness: Up to 3 mm
  • Stamping force: Up to 80 tons
  • Made from flat-rolled materials such as:
    • DC grades
    • Carbon steel grades
    • Stainless steel
    • Aluminum alloys
    • Wrought copper alloys
    • Pre-coated material

In the manufacture of closed sleeves using stamping processes, material use is a significant cost factor. In some cases, only 10% of the strip material would be able to be used.

KERN-LIEBERS pursues a material-saving approach in which flat strip is bent into a sleeve. After separation, the sleeve can be closed using a welding process (laser welding or resistance welding).

For the subsequent processing that then takes place, the full range of KERN-LIEBERS production technology, including all precision machining and heat treatment processes, is available to finish the parts.
