Mould filling by an electro-magnetic pump<br />
The consideration of the drop height makes using force of gravity for mold filling undesirable.<br />
Rather, an electro-magnetic pump is chosen which allows feeding fluid metal with a controlled<br />
rate. In this case, the mold filling does not require a constant mass flow over time but the<br />
pumping rate has to be adapted to the geometry of the part.<br />
The figure below shows anti-gravity mold filling with an electro-magnetic pump used in the<br />
AGSC process.<br />
