In principle yes. It is possible to manufacture metal prototypes with thin
walls using this process. The casting is done by a low difference pressure.
Therefore, the metal structure is different from that of die casting. But it
is more similar as with investment casting. The process is suitable if you
need about 5 to 30 parts. The parts should not be larger than 250mm in each
direction.
The company "Leotech", a service bureau in the area of Stuttgart is running
the process for a plenty of months. Please, contact Martin Bayer, phone +49
