Grinding balls making machine

Product Advantage:

With a rigid sand mold shell, the sand mold’s overall strength is high, does not deform, its adaptability is wide, the easy casting de-molding, and the positioning is reliable, the precision is high.

Molding speed is fast, no need for any painting

The cast-iron mold has the chilling process during the process of the liquid metal crystallization. The grain size of the castings can be finer so that to increase the strength of the castings.

The cavities of the mold, which consists of iron mold and thin sand, has high rigidity, small deformation, and fast cooling features after locking, so it can make the casting with high precision, small machining allowance, and dense structure, which is especially suitable for the grinding balls.
