Milled Part Drawing part
Challenge
Make technically complex custom manufacturing ready for series production in record time
HSP supported a globally operating company in the field of hydrogen technology and plant engineering for the energy industry in making a custom component ready for series production. The component was theoretically and constructively designed by the customer as part of a new development. In close
collaboration with the customer, the complex component was to be brought from prototype to series production readiness within the shortest possible time.
Special technical challenges:
- Complex, angular geometry with tight form and position tolerances
- Use of a difficult-to-machine material
- Milled surfaces with a ground-like appearance
- High precision with simultaneous production-ready series manufacturing
- Iterative alignment between design and feasible production

RESULT
From prototype to series production – precisely and scalably manufactured
The components were adapted to the limits of what is feasible in several iterative steps together with the customer. With modern CNC milling and profound expertise, a practical, production-technically feasible compromise between design and manufacturing was achieved. Today, the component is manufactured scalably in series.
What we have done
From theoretical design to a series-ready stainless steel milled part
Thanks to our experience with complex stainless steel parts and demanding materials, we were able to realize the project with high precision:
- Establishment of an interdisciplinary project team
- Development of manufacturing strategies to achieve maximum precision
- Iterative alignment between customer design and manufacturing capabilities
- Scaling from prototype to series production while maintaining surface quality in a short time
The complex component could thus be successfully integrated into the customer’s series solutions within a few months.
