This article examines questions related to aspects of the production of castings of magnesium alloys in molds made by volumetric stamping without the use of the corresponding tooling. Information is presented on features of the gating-feeding systems used to obtain magnesium-alloy castings in molds made by volumetric stamping. Also examined are features of the effect of small additions of calcium on the susceptibility of alloys of type ML5 to oxidation during casting in stamped molds. It is shown that the use of calcium in magnesium alloys of the system Mg–Al–Zn is promising for preventing their excessive oxidation.
