While aluminum castings are regularly a fast and inexpensive project, repeated part failure prompted a global turbocharger OEM to make a change. They needed a solution that improved the durability and extended the service life of their components.
Together, the turbocharger component suppliers partnered to explore the following alternatives to aluminum casting:
- Machining from solid (MFS) extruded bar stock
- “Open die” forging techniques to reorient microstructures through the process of “upsetting”
In the end, none of these options could produce a quality turbocharger impeller that was both durable and cost effective. The supplier turned to Queen City Forging for answers.
