Turbine wheel of an exhaust gas turbocharger FEINGUSS BLANK

Turbine wheel

The turbine wheel shown is used in the exhaust gas area of a turbocharger. Here, the component is exposed to temperatures of up to 900 °C. The speed of the turbine wheel combined with the temperature conditions lead to an immense load on the component, which posed the greatest design challenge. Added to this are the very thin-walled blade ends, which require the material to conform to the specifications. The best possible conditions can be achieved with nickel-based alloys that are melted under vacuum.

Wastegate system of an exhaust gas turbocharger BLANK CASTING


The Wastegate-System is also used in the exhaust gas turbocharger sector. Here, too, the high temperature in the turbocharger and the behaviour of the component during closing and opening of the exhaust gas flow were the critical variables in the development of the component. By using a suitable material and developing an optimal geometry, a high-performance solution not only within the casting range, but also within the range mechanical treatment and assembly was developed.
