Lightweight Thin-Walled Cast Steel Design Worth its Weight in Gold!

MATERIALICA Design + Technology Award 2013 - EDAG takes Gold

Special tribute to EDAG lightweight production team at this year's MATERIALICA in Munich: the EDAG team headed by Dr. Martin Hillebrecht received the gold award in the category "CO2".

"We are very proud of the fact that, ever since it was established, the MATERIALICA Design + Technology Award has been regarded as one of the most important prizes on the international development scene. More than anything else, what sets the MATERIALICA Design + Technology Award apart from other awards is the way in which it places equal emphasis on two criteria, namely design and technological competence," explained Robert Metzger, CEO at MunichExpo and organiser of the MATERIALICA Design + Technology Awards, who presented the awards along with jury chairwoman Nina Saller (designaffairs GmbH).

As its competition entry, EDAG, in cooperation with the CX Group in Stuttgart, submitted a "vehicle body joint made of thin-walled cast steel", the result of several years' innovative, multi-site cooperation.

One of the advantages of this future technology is the weight reduction (up to 30 %) of components in the vehicle's steel body as a result of minimum wall thicknesses, optimum crash performance and maximum function integration. Its eco-balance is extremely positive, as, compared to lightweight metals or composites, steel is very energy-efficient and low-priced. There are also recycling infrastructures for steel throughout the world.

In addition, the thin-walled cast steel body joint also offers the prospect of tangible economic advantages: for one thing similar joining technologies are used, spot welding can still be carried out or repeated, and what is more, the car manufacturers' chief production officers must surely welcome the great variability and flexibility of this forward-looking construction method.
