Why does a set of die casting dies require the die investment it does?
A. A die casting die or mold is a closed vessel into which molten metal is injected at a high rate of speed, under high pressure and temperature, then rapidly cooled until the solidified part is sufficiently rigid to permit ejection from the mold. To survive these operational extremes and stresses, the die casting die must be built from highest-quality tool steel, heat-treated to the required hardness and structure, with dimensions of the die and cavity machined to exacting specifications for tolerances and part surface finish, to net-shape or near-net-shape production. It is this die quality and precision die construction that makes today’s advanced die casting possible.
