1.11.3 VRC / PRC <strong>–</strong> Processing of chassis parts<br />
Fig. 4 is a flow chart of chassis parts production using VRC / PRC. The alloy most commonly<br />
used for this process is A356 / AlSi7Mg. First, raw material is analysed metallurgically. After<br />
melting, liquid aluminium is distributed by a channel system feeding furnaces equipped with<br />
impellers. From there the melt flows to dosage furnaces feeding the casting furnaces after<br />
every shot.<br />

After solidification the chassis parts are removed either manually (small parts) or robotically<br />
(large, heavy parts). Sawing and deburring is usually automatized. This is followed by X-Ray<br />
with automatic image analysis, heat treatment to achieve suitable mechanical properties,<br />
crack detection, eventually machining and shipping.<br />
