Gravity casting is a manufacturing process that uses gravity to fill a mold with liquid metal. It is typically used for complex shapes and thin walls and can be used to produce parts from aluminum, brass, bronze, and other metals. The process involves pouring molten metal into a pre-made mold or die, then allowing it to cool and solidify in the shape of the desired part. Gravity casting offers several advantages over other methods of metalworking such as sand casting or die casting including reduced labor costs, improved dimensional accuracy, and higher-quality finished products.
