Magnesium castings in aGerman die casting foundry. Does the new MAXImolding process offer new perspectives and qualitative advantages<br />
for the light metal alloys parts?<br />

alloy injection molding inthe<br />
digital foundry ofthe future<br />
By inventing anew metal molding process, anew light metal injection molding machine<br />
and anew self-learning foundry, Ashley Stone’s vision is to make this industry fit for the<br />
“green” 21st century. Since 1999, Jacobsen Real-Time X-Ray Machinery of Canada has<br />
been working to eliminate defects in castings and to do so Ashley Stone combined the<br />
advantages of Thixomolding and hot and cold chamber high-pressure casting machines<br />
into the MAXImolding machine and process.<br />
By Ashley Stone, Toronto, Canada, and Edo Meyer, Siegsdorf, Germany<br />
The MAXImolding machine is invented<br />
from scratch and can produce<br />
light alloy components with less<br />
than 0.5 %ofporosity. The next step is<br />
to implement afully automated, self-learning<br />
light alloy forming cells in which<br />
the MAXImolding machine works in tandem<br />
with Automatic Image Recognition<br />
(ADR) X-ray inspection. The real time<br />
X-ray feedback via two independent<br />
loops allows the process to be optimized<br />
in real time cycle to cycle.<br />
Thixomolding<br />
Casting has been carried out according<br />
to the same principle for more than<br />
5,000 years. The metal is heated in a<br />
pot so that it becomes aliquid. It is<br />
then metered into the mold with a<br />
