Abstract
The present invention relates to a system for contactless induction of high-frequency vibrations in a volume of molten metal during the manufacturing of a metal component or a metal matrix composite component. The system includes a moveably arranged electromagnetic primary coil, adjustment means for adjusting the position of the primary coil, and a control unit for controlling the position of the primary coil to a predefined distance above, but not in contact with, an upper free surface of the molten metal. The molten metal may be contained in a foundry crucible during manufacturing. The system can be used as an additive manufacturing system, with the primary coil arranged above the melt pool. A secondary low-frequency electromagnetic coil may be arranged around and at a distance from the molten metal to induce flow and/or vibrations in the molten metal.
