Forging a Turbo Charger

Turbo Impeller Case Study

The Problem:


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.

The Solution:


Our expertise in the forging process created a near net shape product with enhanced metallurgical properties. No other manufacturing method could create such a reliable product that delivered exactly what these suppliers required.

The forged turbocharger impellers we produced showed:

  • Directed strain energy to target micro structure transformation
  • Enhanced critical structural fatigue properties
  • Increased service life
  • Upgraded metallurgical properties through rapid, uniform heating
  • Improved process uniformity and throughput
  • Conserved material usage
