More Information
Summary:Provided is a casting method comprising: a step which a nozzle, capable of ascending and descending, stands on a first position and moves to a second position having a different level with the first position, and partially injects molten metal received in a casting device to a mold sequentially; and a step where the molten metal gradually becomes solidified in the mold. As such, the casting method provides a casting product which does not have a shrinkage cavity and has a high casting recovery rate. 승하강 이동이 가능한 노즐이 제 1 위치에서 대기하다가 상기 제 1 위치와 레벨(level)이 상이한 제 2 위치로 이동하여, 상기 주조장치의 내부에 수용된 용융금속을 주형에 순차적으로 분할 주입하는 단계; 및 상기 주형 내의 상기 용융금속이 점진적 응고되는 단계;를 포함하는, 주조방법을 제공한다.
