Since the distance between every point on a spherical surface to ball center is equal, we use a plane through ball center as parting plane. If the parting direction is normal to the parting plane, that will avoid interfering situation when parts between mold and object. Therefore in this invention, some spherical protrude profiles be setup on the top mold and down mold of the mold of the ball chain, and the parting direction follow an incline direction to ball chain so as avoiding the interfering situation when mold parts from object. And using the method can reduces the degree of difficulty to manufacture the ball chain, and improves the lubricating effect for bearing using ball chain.
