Gravity Die Casting: Definition, Importance, How It Works

Gravity die casting is a metal casting process where molten metal is poured into a durable metal mold using gravity. Once the metal cools and solidifies, the mold is opened to retrieve the casting. In sand casting, compacted sand is placed around a wooden or metal pattern, and additional cores are inserted to create internal features.
