The complexity of the manufacturing and machining processes for turbine housings made of cast steel and the high costs arising in connection with them has raised the question of what benefits the customer derives from these technologies.
Thin walls are desired to significantly reduce the weight of the turbine housing and simultaneously reduce the thermal inertia of the turbine housing. This leads to faster activation of the catalytic converter during the cold-start phase of the engine, which in turn significantly improves the emission levels of the vehicle.
