As a precision metal casting method, die casting can be used to produce parts of varying complexity with tight tolerances. The objective of die casting is to inject molten metal under pressure into a mold or die made of metal. This cools quickly and solidifies the metal in whatever particular shape has been chosen. Die casting technology stands on three legs: the first being precision molds, the second high-pressure injection systems and finally automated procedures to ensure consistency and quality assurance in product output before checking them for various defects that may have been introduced during manufacture. Die casting has many applications -- in the automotive, aerospace, consumer electronics and other industries. It is acclaimed for its ability to produce parts that usually require no or little post-casting work, thus lowering costs and lead times.
