Introduction to gravity casting:
Gravity casting refers to the process of injecting molten metal into a mold under the action of gravity of the earth, also called casting. Generalized gravity casting includes sand casting, metal casting, investment casting, lost foam casting, mud casting, etc.; narrow gravity casting refers to metal casting. The molten metal is generally poured into the gate by hand, and the product is obtained by filling the cavity with the self-weight of the molten metal, exhausting, cooling, and opening the mold. The process flow is: smelting, pouring filling, exhausting, cooling, mold opening, heat treatment, gold processing.
