1.8 Vacuum die castings<br />
1.8.1 Characteristics of VDC<br />
<strong>Aluminium</strong>-intensive cars like Audi A2, Audi A8 or Ferrari Modena rely heavily on Vacuum Die<br />
<strong>Casting</strong> (VDC) for the space frame design. VDC has several characteristics that make it<br />
highly attractive for automotive applications:<br />
thin walls in large structures: Designs using a minimum wall thickness well below 2<br />
mm.<br />
joining with standard welding techniques as well as Laser welding and self-piercing<br />
rivets.<br />
crash worthy structures (i.e. A-pillar of Audi A2, frame Ferrari Modena)<br />
wide selection of alloys including heat treatable and non-heat treatable alloys.<br />
high productivity.<br />
