A cylindrical riser with diameter-to-length ratio=1.5 is to be designed for a sand casting mold. The casting geometry is illustrated in Figure below. If the mold constant - 19.5 min/in² in Chvorinov's Rule, determine the dimensions of the riser so that the riser will take 0.75 minute longer to freeze than the casting itself. 3.50 inches 20.05 inch 0.5 inch 1.4 inch 41102 R=2.0 inch R=1.0 inch 18 inches 0.5 inch 1 inch $0.375 inch

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.
