Gravity Casting: A Solution for High-Quality Metal Castings
Dense Structure, Stable Performance, Suitable for Medium to High-Volume Production
- Utilizing gravity for natural mold filling results in a more stable internal structure of the casting.
- Suitable for high-quality casting of non-ferrous metals such as aluminum alloys.
- Excellent dimensional consistency, minimal machining allowance.
- A mature casting process that balances performance and cost.
What is gravity casting?
Gravity casting is a casting process in which molten metal is naturally poured into a metal mold or sand mold under the influence of gravity. Compared to high-pressure die casting, the filling process in gravity casting is more stable, which helps reduce porosity and internal defects, resulting in a denser casting structure and more stable mechanical properties.
This process is widely used in the manufacture of metal parts that require high strength, sealing, and reliability.
