Concept explainers

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.

When casting a 4x10x20 in. Part, which has a top overflow with a H / D = 1.5 ratio, you want to determine the height and diameter of the overflow to prevent shrinkage in the part to be cast. Note: Remember that to achieve this, the overflow has to solidify some time after the piece has solidified, since in this case the overflow acts as a riser.

A flat plate is to be cast in an open mold whose bottom has a square shape of 12.5 cm by 12.5 cm. The mold is 7.0 cm deep. A total of 350 cm³ of molten aluminum is poured into the mold. Solidification shrinkage is known to be 6.25%, which is a volumetric contraction, not a linear contraction. Table 7.1 lists the linear shrinkage due to thermal contraction after solidification. If the availability of molten metal in the mold allows the square shape of the cast plate to maintain its square dimension until solidification is completed, determine the final dimensions (width and height) of the plate.
