Forming Parts

Forming parts are products made using the same cold-extrusion production process as for connecting elements.

They are generally distinguished by a more complex geometry and can be made only using a multistage pressing process. Some examples for such products are: door hinge axles, drive shafts, locating pins, cores for rubber-to-metal elements, ball pins or bushings.

Development processes carried out jointly with our customers have often turned out that there is a more efficient production variant of cold forming available for mechanical parts processed so far rather expensively. To do so, some minor modifications are required on the product which will not adversely affect its functionality. ESKA applications engineering is always by the side of our customers to provide adequate support. 

The use of forming parts features a high technical and economic potential for our customers.

The product range of forming parts ist defined as follows:

  • shank diameter M4 up to max M40
  • maximum outer diameter 50 mm
  • length 6 mm up to 220 mm
  • cup depths approx. 40 mm

Boron-alloyed steel grades (e.g. 23MnB3), low-alloyed (e.g. 34Cr4) and alloyed steel grades (e.g. 40CrMoV4.7) and aluminum are used as materials. In accordance with the definite application, the material can be selected together with the customer.
