    magnetic mold

    The technology used an expendable pattern around which metallic particles were bonded together by application of a magnetic field. Once the cast metal solidified in the mould, the magnetic field was removed. The metallic particles fell away and could be reused in subsequent castings and the part itself was recovered.

    Production of five different pieces using four different metal alloys confirmed that the process produced complex shapes. Components exhibited better metallurgical and mechanical properties than pieces obtained by the three most common expendable mould techniques. In addition, the magnetic mould process reduced cycle time compared to the other foundry processes.

    Magnetic mould casting (MMC) is an application of electromagnetism to the process of casting. Steel shots constitute the mould that is formed by application of magnetic field on them.
    The application of magnetic field that induces magnetic bonds between steel shots which gives strength to mould.

    this is a huge over-engineering of something simple.
    they have replaced a plain bucket of sand
    with an electromagnet and steel shot in a lost foam shell casting process

    Sure seems that way to me too, at least from reading the article, it's not obvious how this would be an improvement over a plain bucket of sand.
