Highlights in the product portfolio in automotive engineering:

Use of precision steel tubes instead of solid material for stabilizers

Use of precision steel tubes instead of solid material for stabilizers.

 

Customer benefits:

  • significant weight reduction
  • reduced manufacturing efforts
  • enhanced properties of the components
Lightweight construction with TDT® Tailor Drawn Tubes

The TDT® Tailor Drawn Tube method allows a flexible adjustment of the wall thicknesses of the pipe bodies to the load that arises. The developed drawing process ensures consistent homogeneous properties.

Depending on the initial construction, the potential for weight reduction is approximately 20%.

Key points of the pipe manufacturing process: 

  • Longitudinally welded pipe, high-ductility RF welding seam, proven in the IHU process
  • Newly developed drawing process enables homogeneous mechanical / technological properties across construction length
  • Optimized selection of materials

Customer benefits:

  • High degree of accuracy / tight tolerances
  • Homogeneous seam area
  • High degree of forming capacity
  • Mechanical properties adjustable by drawing and annealing process
  • Multiple lengths and large pipe lengths are possible
  • Low tool costs
