2025 Top 10 Gravity Casting Factory in China

Introduction to Gravity Casting

Gravity casting is a metal casting process that relies on gravity to fill the mold cavity with molten metal. It is one of the oldest and most widely used casting methods. In this process, molten metal is poured into a mold from a ladle or a crucible, and the force of gravity causes the metal to flow and take the shape of the mold cavity. Gravity casting offers several advantages, such as relatively simple equipment requirements, the ability to produce large and complex parts, and good surface finish and dimensional accuracy for many applications. It is commonly used in various industries, including automotive, aerospace, machinery, and consumer goods, to manufacture components like engine blocks, wheels, and decorative parts.
