Cold pressed parts

When forming metal one can make recourse to a great number of processes that fall under the umbrella term “cold forming”. Through the combination of different procedures, it is possible to manufacture shape-moulded parts with extraordinary engineering properties at very favourable costs. As needed, machine lathing procedures can also be included.  

Cost Efficiency

The forming processes exploit the plastic formability of many metals. Within these physical limits there are many advantages in comparison with classical machining production:

  • Significantly higher production speeds
  • A considerable savings of material, since there is almost no production loss  
  • Many contours that can only be manufactured using machining procedures with a great expenditure of time can now be realised very easily  

The advantages of cold forming only hit the break-even point as of a certain number of pieces. The fixed costs are higher than for machine lathing. The reasons for this are:  

  • Higher investment costs for machines
  • Higher tool costs
  • Higher retooling costs 

Technical advantageous component properties

The processes for cold forming can be used quite advantageously in the realisation of:  

  • Parts with large Ø differences  
  • Hollow parts
  • Complex axial geometries e.g. knurls, gears
