In gravity die casting process, reusable metallic molds are used for creating the mold cavity where molten metal are poured without applying any force or pressure other than gravity. A silicate based coating is sprayed over the inner surface of the mold cavity before pouring the molten metal.
Fig.1: Gravity Die Casting
Level of surface finish achieved: 3.2-0.40 micro meters
Advantages:
- Good surface finish compare
- Low cost setup
- Waste can be recycled
- Quick cycle time
Disadvantages:
- Suitable for simple components
- Chances of defects are high
Ideal applications: Suitable for producing aluminum alloy and other similar light metal components. This process gives smoother surface than sand casting.
