Thin-walled castings production technologies

Investment casting methods are used to manufacture the cast parts of devices, based on production of monolithic molds from liquid-moving fast-hardening foundry sand with gypsum as a binder. The metal cooling rate diminution and increasing in rate of its motion in the mold are the needed conditions of mold filling assurance for preparing the thin-walled castings. A nomogram is plotted to choose the process parameters under conditions of evacuation of ingot molds. The nomogram sampling showed that the parameters chosen provide the manufacture of castings with the wall thickness of 0.6-1.2 mm.
