High-performance investment castings for turbocharger housings in demanding automotive applications
Investment castings for turbocharger housings are the preferred choice for high-temperature and high-performance applications, given the exacting environments turbochargers function in. Easily identified by their conch-like spiral shape, turbocharger housings come in single and dual internal passages (volutes) with rectangular (T) and circular flanges (V-band). The flanges themselves may be single scroll (referring to a single volute) or twin scroll by design.
At Super Quali Cast, we are a leading manufacturer of investment castings for turbocharger housings, producing all the above-mentioned configurations. Our T and V-band single and twin scroll housings are made with austenitic stainless steel that justifies the ‘hot side’ tag associated with turbocharger housings. We supply our turbocharger housing castings to domestic and international tier-1 suppliers and OEMs.
Investment Casting Process for Turbocharger Housings
- High-Precision Molding: Forms uniform shells and inner cavity.
- Gravity Pouring: Minimizes misruns and geometric inaccuracies.
- Heat Treatment: Enhances material properties such as hardness and strength.
- CNC Machining: Ensures tight tolerances and excellent surface finish.
- Final Inspection: Visual and physical checks using universal testers and precision gauges to ensure defect-free output.

FAQs
What is the main job of a turbine housing?
Turbine housing is to act as a collector of exhaust gases. It then directs the hot exhaust gases to the turbocharger. Since it handles hot temperatures, investment castings for turbocharger housings are typically made from heat-resistant alloys like austenitic stainless steel.
What are volutes in relation to turbines?
Volute refers to the internal pathway in a turbocharger housing. Turbochargers usually have one internal passage, but two passages are not uncommon.
What is A/R and why is it important for turbochargers?
A/R stands for Area over Radius. It’s important because it describes the size of the volute. Small A/R can provide a quick boost at low speeds but create more backpressure later on. Large A/R can delay boost speeds, but can help the engine breathe better and make more power at higher RPMs.
Can turbocharger housings be forged?
Yes, turbocharger housings can be forged. However, its unusual shape, inherent complexity, and the need for tight tolerances make forging difficult. It is better suited to investment casting, which provides near-net shape repeatedly.
What is the benefit of a V-band flange over a T flange?
Rectangular T flanges need four or more bolts to be secured thoroughly. V-band flanges have circular ends, which require only a single clamp for secure sealing, making the installation process seamless.
