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