Most interested research fields in lost foam casting is focused on aluminum and magnesium alloy

their defects formation mechanism

foam pattern making and quality description

white zone pattern making.These researches indicate that the pattern with low fusion degree in center

high fusion degree in surface

and uniform density and smooth surface are suitable for the production of high quality castings in lost foam casting.In addition

X ray

SEM and numerical simulation have been employed to the estimation and prediction of bead filling mold

pattern making and quality of finished pattern.
