Effect of Casting Section Thickness and Coating Thickness on the Fluidity and Molten Metal Velocity of A356 Aluminum Alloy in Lost Foam Casting Process

In this research the effect of 6 different coating thicknesses and 6 different casting thicknesses on fluidity of A3 5 6 aluminum alloy in lost foam casting process has been investigated by means of Campbell fluidity pattern. In each mould the thickness of coating was constant and the fluidity through each coating thickness has been measured with accuracy of ± 1 mm. As the casting thickness increases, in each mould, fluidity increases, but by varying the coating thickness in constant casting thicknesses, the maximum fluidity lengths were obtained in a specific optimized coating thickness for each strip. Also the effect of coating thickness on molten metal velocity in LFC process was studied by using accurate thermal analysis equipment
