The molten metal is pumped into the cavity of the permanent mold during the die-casting process under tremendous pressure and used for (non-ferrous) metals with low melting points. The die casting tools, which in addition to the molds mentioned earlier, include mold inserts, cores, slides, and ejectors, are manufactured of high-strength hot-work steels like X40CrMoV5-1 (1.2344) or uni... http://www.advancetechnologies.co/pressure-die-casting-tool-manufacturing.html
