Emissions-Free Foundry now online
BMW’s Landshut plant will soon be the world’s first foundry with emissions-free sand core production. This light-alloy foundry is introducing a new sand core production method for gravity die-casting, when organic binders will be replaced by highly eco-friendly inorganic binders, which in turn generate no pollutant emissions.
The foundry uses these to produce aluminum crankcases and cylinder heads for 6-cylinder diesel engines across their entire line of vehicles. In addition to the environmental benefit, this process also has economic and ergonomic benefits. The strength of the components are enhanced, resulting in a more durable product.
“We will be able to fully amortise the investment in tools and equipment, along with our development costs, in the space of just a few years at most thanks to increased productivity, and thanks to savings on tool maintenance, tool and workshop air extraction systems and waste air treatment systems,” says Dr Wolfgang Blümlhuber, head of the BMW light-alloy foundry.
Working conditions have improved as well, with a simplified process free of harmful waste. Productivity, in turn, has increased 10 percent as well, making this an impressive start down the road to complete decommission of emission-producing parts and processes.
