Gravity Die Casting
Gravity die casting is a permanent mold casting process in which molten metal is poured into a reusable metal mold using gravity rather than external pressure. The mold is typically made of steel or cast iron and can be used repeatedly, making the process suitable for medium to high production volumes.
This process offers better mechanical properties compared to sand casting due to faster cooling rates and controlled solidification. It is commonly used for non-ferrous metals such as aluminum, magnesium, and copper alloys.
Advantages
- Improved mechanical strength and durability
- Better surface finish than sand casting
- Reusable molds reduce long-term cost
- Consistent quality in production
- Lower porosity compared to traditional casting
