Overview of Casting Technology

• Casting is usually performed in a foundry

Foundry = factory equipped for making molds,melting and handling molten metal,performing the casting process, and cleaningthe finished casting

• Workers who perform casting are calledfoundrymen

Open Molds and Closed Molds

Figure 1 Two forms of mold: (a) open mold, simply a container in the shape of the desired part; and (b) closed mold, in which the mold geometry is more complex and requires a gating system (passageway) leading into the cavity.
