/The total solidification times of three casting shapes are to be compared: (1) a sphere with diameter= 10 cm, (2) a cylinder with diameter and length both = 10 cm, %3D and (3) a cube with each side = 10 cm. The same casting alloy is used in the three %3D cases. (a) Determine the relative solidification timesfor each geometry. (b) Based on the results of part (a), which geometric element would make the best riser? (c) If the mold constant = 3.5 min/cm2 in Chvorinov's rule, compute the total solidification time for each casting.

Metal Casting

Metal casting is described as a manufacturing process in which a mold cavity is produced by sand, and molten metal is filled inside a mold cavity. The desirable shaped object is achieved after the solidification of molten metal. Large metal objects like machine beds, motor bodies, and others can easily be manufactured using metal casting. The place or shop where metal casting is performed is called foundry.
