Title:
APPARATUS AND METHOD FOR MANUFACTURING METAL FOAM
Document Type and Number:
WIPO Patent Application WO/2011/136444
Kind Code:
A1
Abstract:
The present invention relates to an apparatus for manufacturing metal foam, the apparatus comprising: a thickening unit for thickening molten metal; a foaming unit connected to the thickening unit by means of a transfer unit, for mixing the molten metal thickened by the thickening unit using bubbles supplied through an aerator so as to foam the metal; and a suctioning unit for suctioning the metal foamed by the aerator and transferring the metal foam to a mold of a predetermined shape. The aerator comprises a foam-mesh type first bubble size controller for primarily controlling the size of the bubbles, and the suctioning unit comprises a foam-mesh type second bubble size controller for secondarily controlling the size of the bubbles. By controlling the bubbles in metal foam to be uniform in size, the uniformity of the size of bubbles in the metal foam can be improved in order to significantly improve the mechanical strength, energy absorption performance, etc. of aluminum foam.
