This new development offers numerous advantages over previous designs. Compared to double-shell solutions, this method enables thin-walled components to be produced in a single production step, which results in material savings, cost reduction and weight optimization. It also eliminates weld seams, improves structural integrity and increases reliability.

Core of the development

The core of the development lies in projectile technology in combination with fluid injection technology for thin-walled cooling structures that can be seamlessly integrated into structurally integrated components such as bicycle, motorcycle and automotive components. The innovative product and process design makes it possible to guide asymmetrical projectile shapes along the curved flow paths in the process without them tilting or getting stuck. This new approach opens up a wide range of applications in various industrial sectors and offers an efficient solution to the challenge of manufacturing thin-walled components with complex cooling structures.
