The benefits of gravity die casting are:
No external force is necessary for pushing the molten metal.
Gravity die cast components have better density than sand casting parts.
This process costs less than most other processes like vacuum casting, squeeze casting, etc.
Gravity casting parts have less porosity and better grain structure than sand casting parts.
For medium or small volume production, it is cheaper than other methods.
Gravity casting components have good mechanical properties, which are great for heat treatment.
The component’s surface has a better finishing than most other casting parts.
Some of the drawbacks of gravity die casting are:
Manual gravity die casting takes more time than other casting processes.
Automatic gravity die casting parts are less precise than manual gravity casting parts.
It is complicated to manufacture complex parts using this method.
