PRODUCTION METHOD OF FOAMED METAL, PRODUCTION DEVICE OF FOAMED METAL

摘要

To provide a production method foamed metal, which can perform a foaming step at a low cost, can produce a foamed metal having a size larger than ever, and can control a shape of the foamed metal.SOLUTION: By using a transportation part 2 that transports a precursor 11 in which a foaming agent is mixed in metal, a mold 5 that transmits light, a light source 4 that illuminates light on the precursor 11, and the precursor 11, molds 5 are arranged to a plurality of the precursors 11, the plurality of the precursors 11 are transported by the transportation part 2, in a state where the precursors 11 are transported, light is irradiated to each of the precursors 11 by transmitting the mold 5 from a light source 4 to heat to make each of the precursors 11 foam to join with the adjacent precursors 11 to prepare a foamed metal 12, and by controlling a shape of the foamed metal 12 by the mold 5 to produce a foamed metal 12.SELECTED DRAWING: Figure 1
