Molding of Aluminum Foams by Using Hot Powder Extrusion

So that you can form aluminium foams directly from powder, a combined process of popular powder molding and extrusion is proposed. Aluminum powder mixed with a foaming agent is without question extruded into the mold through the die heated to a heat higher than the melting stage, and the mold can be filled with the light weight aluminum foam. Whenever a stainless steel pipe can be used for a simple mold, an metal foam bar is obtained of which the relative density varies between 0.2 and 0.3. The molding of light weight aluminum foam through the use of single screw extruders three types of mold form shows the effect of gravity and friction. The result of gravity is going to be significant when a huge step is present at the connection between the mold inlet and the die store, and friction is usually dominant where foam is normally mold in a narrow space.
