Gravity die casting consists of pouring molten metal in a metallic mould but without external pressure. The hydrostatic pressure is created by the risers. Therefore, the mould cavity not properly filled and the casting gate is not superior to that in case of pressure die casting, as in this method, a definite amount of molten metal is fed into the mould and then close fitting cores are pushed in the cavities so that the molten metal can be forced into the mould cavities
Thus, because of the above reasons the gravity die casting has no future due to the emergence of pressure die casting.
