Die Casting is the process of forcing molten metal under high pressure into the cavities of steel molds, called dies. Dies range in complexity to produce any non-ferrous metal parts (that need not be as strong, hard or heat-resistant as steel) from sink faucets to engine blocks (including hardware, component parts of machinery, toy cars, etc).
 

In fact, the process lends itself to making any metal part that must be precise, must have a very smooth surface that can be bright plated without prior polishing and buffing, have very thin sections, must be produced much more economically, must be very flexible in design; a single die casting may have all the features of a complex assembly.
