PROBLEM TO BE SOLVED: To provide a casting machine capable of casting a raw material liquid substance without exerting an effect on the material of a supply tank even if the temperature of the raw material liquid substance of the supply tank is set slightly lower and the temperature of the piping going toward a mixing chamber through a metering pump is set slightly higher in order to increase the reaction speed of a urethane, and a liquid substance supply method. SOLUTION: In the casting machine having a route, which discharges a definite amount of the raw material liquid substance to the mixing chamber from the supply tank of the raw material liquid substance through piping by the metering pump, and a route for circulating the raw material liquid substance without discharging it to the mixing chamber, the circulating route has a liquid circulating confluent part between the supply tank and the metering pump. The liquid substance supply method is also disclosed. COPYRIGHT: (C)2006,JPO&NCIPI
