Emission-free foundry
The new BMW 5 Series Sedan comes with petrol and diesel engines
featuring cylinder heads and crankcases from the world’s first emission-free
foundry in Landshut about 60 km north-east of Munich. To avoid emissions
in the casting process, the light-alloy foundry at the BMW Plant is converting
the production of sand cores in the die-casting process, replacing
conventional organic binding agents by inorganic binding agents particularly
friendly to the environment. This reduces emissions potentially harmful to
the environment to almost zero.
Introducing this innovative production method, the light-alloy foundry is
reducing emissions from combustion residues in general by 98 per cent.
This ultra-low-emission production process is being introduced in Landshut
initially for the aluminium crankcases and cylinder heads of BMW’s six-cylinder
diesel engines. And currently the process of inorganic sand core production
is being carried over step-by-step to the entire range of production in the
light-alloy foundry.
