Simulation and Component Design

Service offer#

Holistic simulation and design of process-, material- and stress-adapted construction solutions

Our core expertise is holistic simulation and component design, starting from the joining process up to the loaded structural component. Thanks to the close cooperation with the process development team (e.g. laser beam welding, friction stir welding, magnetic pulse welding) and our expertise department in materials technology, we are able to generate and analyze realistic simulation models.

Many different benefits can be derived from our simulations:

  • Innovation: Designed to meet the requirements of the process and the loading
  • Cost and time savings: Shortening of product development times
  • Safety: Securing and increasing component reliability
  • Lightweight construction: Utilizing the potential of lightweight construction
