Etteplan’s hybrid manufacturing case: Rosendahl Nextrom

Rosendahl Nextrom approached Etteplan AMO team with a challenging case. The aluminum component in question operates in a hostile environment, with temperatures exceeding 1000°C. In order to ensure that temperatures within the component remain below its melting point, channels for cooling water must be integrated into the part. An earlier design for this part consisted of a complex structure requiring 8 manufactured components, 11 welds, and machining after each individual weld. This first design was very difficult to manufacture and was not feasible for production. The goal of the redesign was to utilize additive manufacturing (AM) where needed to improve manufacturability and reduce the number of welds and components, while simultaneously achieving a similar level of cooling within the product.
