In order to improve the mold filling in molding of aluminum foams, a molding process by using a rotating mold is proposed. Aluminum powder mixed with a foaming agent is formed to a precursor by hot powder extrusion and extruded into the mold through the die heated to a temperature higher than the melting point, and then the mold is filled with the aluminum foam. When the diameter of a cylindrical mold is large, the influence of gravity is significant and the mold is not filled successfully. In the proposed process, the aluminum foam is extruded into the rotating mold of large diameter and the shape of foam is improved. However, the effect of the mold rotation on the mold filling is limited.
