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.

Problem 1 Suppose we want to cast a magnesium bar 20x20x45 mm³. We are to use a mid gating (exactly at the parting line) system with two runners and multiple ingates (no bends in runner), a top riser of 1:1.2 (D:H) ratio, and the bar lying down. The pouring cup to be used has a height of 10 mm. What would be the riser dimensions for this casting? Use the JB Caine Method (a, b, c = 0.10, 0.06, 1.08). If the choke area is 20 mm?, how long would the pouring time be?
