Meaning of CASTING in English

CASTING

n.

Pouring of molten metal into a mold , where it solidifies into the shape of the mold.

The process was well established in the Bronze Age , when it was used to form bronze pieces now found in museums. It is particularly valuable for the economical production of complex shapes, ranging from mass-produced parts for automobiles to one-of-a–kind production of statues, jewelry, or massive machinery. Most steel and iron castings (see cast iron ) are poured into silica sand. For metals of lower melting point, such as aluminum or zinc, molds can be made of another metal or of sand. See also die casting , founding , investment casting , lost-wax casting , patternmaking .
