The main advantages of gravity casting parts include the following:
Fewer internal pores in the casting: During the gravity casting process, the aluminum liquid fills the cavity by its own weight, reducing the formation of internal pores, which makes the internal quality of the casting higher and can be further strengthened by heat treatment.
Low mold cost and long service life: The molds used in gravity casting are usually made of heat-resistant alloy steel. Although the purchase cost of metal molds is high, they have a long service life and are suitable for mass production, thereby reducing the mold cost per unit product.
Suitable for mass production: The gravity casting process is simple and suitable for mass production, which can improve production efficiency and reduce production costs.
Wide range of materials: Gravity casting is suitable for a variety of materials, including ferrous and non-ferrous metals, and is suitable for the production of castings of various complex shapes.
High dimensional accuracy: Gravity casting can obtain higher dimensional accuracy and lower surface roughness values, and the quality stability of castings is good.
