Summary:Provided is a method to manufacture a metal ball comprising: a first step of rotating a casting device wherein spherical casts are arranged in a radial direction; and a second step of successively dividing a certain molten metal, injecting the molten metal to a rotating casting device, and performing a gradual coagulation of the injected molten metal when the molten metal is moved to the spherical casts by a centrifugal force. The second step is repeated a plurality of times. 본 발명은 구 형상의 주형이 방사상으로 배치된 주조장치를 회전시키는 제 1 단계; 및 회전하는 상기 주조장치에 소정의 용융금속을 순차적으로 분할하여 주입하고, 주입된 상기 용융금속은 원심력에 의해 상기 구 형상의 주형으로 이동되어 점진적 응고가 수행되는 단계를 복수회 반복하는 제 2 단계;를 포함하는, 금속볼의 제조방법을 제공한다.
