die casting


die casting

Forming metal objects by injecting molten metal under pressure into dies or molds. An early and important use of the technique was in the Linotype machine (1884), but the mass-production automobile assembly line gave die casting its real impetus. Great precision is possible, and products range from tiny parts for sewing machines and automobiles to aluminum engine-block castings.
