Molding of Aluminum Foams by Using Hot Powder Extrusion

As a way to form lightweight aluminum foams directly from powder, a combined process of heated powder molding and extrusion is proposed. Aluminum powder mixed with a foaming agent is certainly extruded in to the mold through the die heated to a heat greater than the melting point, and the mold is definitely filled with the aluminium foam. Whenever a stainless steel pipe can be used for a straightforward mold, an metal foam bar is obtained which the relative density varies between 0.2 and 0.

The molding of aluminum foam through the use of three types of mold condition shows the impact of gravity and friction. The result of gravity is going to be significant when a large step is present at the connection between the mold inlet and the die wall plug, and friction is undoubtedly dominant in cases where foam can be mold in a narrow space.
