This study investigated the effects of the restraint from green sand mold for cast iron during cooling process. Gray cast iron (JIS FC300, almost identical to ASTM 45) was cast in a green sand mold, and the constraining force to the casting from the sand mold and the contraction of the casting were measured dynamically from the beginning of solidification to 200°C. The measurement results obtained using the green sand mold were compared with those using the furan sand mold. The maximum constraining force in the green sand mold case was lower than that in the furan mold case. The contraction in the green sand mold at 200°C was greater than that in the furan sand mold. The results showed that the green sand mold restrains the casting less than the furan sand mold during cooling process.
