Top 10 Gravity Casting Manufacturers 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, the molten metal is simply poured into a mold, and gravity pulls it down to fill all the cavities and details of the mold. This method is suitable for a variety of metals, including aluminum, copper, and iron. Gravity casting offers several advantages such as high dimensional accuracy, good surface finish, and the ability to produce complex shapes. It is commonly used in industries like automotive, aerospace, and consumer electronics.
