Improvements to the vacuum die-cast
process now mean that much larger
components can be produced, such as the A-
and B-pillars in the Audi A2.
Cast parts in the ASF

A8
Joint elements with tolerance compensation
These parts are manufactured using the
vacuum die-cast process (Vacural
®
).
Pore arms and easily weldable parts are a
requirement for the subsequent assembly
process.
These parts display good properties in terms
of their crash response with regard to
deformation and energy absorption.

Multi-functional large cast parts with
minimised wall thickness and weight, plus
improved dimensional accuracy of
components.
New alloy developments have meant that the
casting process has been further developed,
recycling has been improved and subsequent
heat treatment is no longer necessary.
Together with optimised peripherals (tool
technology), the dimensional accuracy of the
parts has been improved.
Due to these large cast parts it has been
possible to expand the opportunities
available through existing joint technology.
The result is a reduced number of parts, and
therefore less bonding work needs to be
carried out.
Thanks to these optimised design options,
the integration of multi-functionality and a
reduction of the number of parts has been
achieved.
