Casting

Casting is a manufacturing process by which a liquid material is usually poured into a mold, which contains a hollow cavity of the desired shape, and then allowed to solidify. The solidified part is also known as a casting, which is ejected or broken out of the mold to complete the process. Casting materials are usually metals or various cold setting materials that cure after mixing two or more components together; examples are epoxy, concrete, plaster and clay. Casting is most often used for making complex shapes that would be otherwise difficult or uneconomical to make by other methods.

Casting is a 6000 year old process. The oldest surviving casting is a copper frog from 3200 BC.

Famous quotes containing the word casting:

    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)

    All we know
    Is that we are a little early, that
    Today has that special, lapidary
    Todayness that the sunlight reproduces
    Faithfully in casting twig-shadows on blithe
    Sidewalks. No previous day would have been like this.
    John Ashbery (b. 1927)

    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)
