The effect of the thermal insulation coat on the mold filling for a thin wall aluminum alloy casting in the expendable pattern casting process was investigated experimentally and theoretically. Thin wall aluminum alloy plates were cast by the EPC process using the thermal insulation coat. The fluidity length and melt velocity were measured. Even when the thermal insulation coat was used, the fluidity length of the melt did not increase so much. The fluidity lengths were predicted by using measurement values of the melt velocity. The predicted values were in approximately agreement with experimental values.
