Casting
In casting, a sprue is the passage through which a molten material is introduced into a mold, and the term also refers to the excess material which solidifies in the sprue passage. In sand casting, the sprue is formed by a dowel which is removed from the sand to make the hole into which the metal is poured.

Famous quotes containing the word casting:
“For the gods, though slow to see, see well, whenever a man casting aside worship turns folly.”
—Sophocles (497–406/5 B.C.)
“This I do know and can say to you: Our country is in more danger now than at any time since the Declaration of Independence. We don’t dare follow the Lindberghs, Wheelers and Nyes, casting suspicion, sowing discord around the leadership of Franklin D. Roosevelt. We don’t want revolution among ourselves.”
—Lyndon Baines Johnson (1908–1973)
“Reason sits firm and holds the reins, and she will not let the feelings burst away and hurry her to wild chasms. The passions may rage furiously, like true heathens, as they are; and the desires may imagine all sorts of vain things: but judgement shall still have the last word in every argument, and the casting vote in every decision.”
—Charlotte Brontë (1816–1855)
