Aluminum gravity casting can also be referred to aluminum gravity die casting,aluminum metal mold gravity casting or aluminum permanent mold casting. Here they describe a same kind of aluminum casting process.

We can make the weigh of range from 0.01kg to 15kg/pcs for aluminum pressure die castings, it is including lighting components, gearbox, brake system, engineer components, bike components.

Aluminum gravity casting and sand casting process is always used for heavy part with big wall thickness and very strong mechanical property after T6 heat treatment. Its also better to avoid porosity inside casting after secondary machining.

Aluminum gravity casting and sand casting process is  better to avoid porosity inside casting after secondary machining. Gravity casting part is nice looking with better surface than sand casting, but sand casting is more flexibility even it is very complicated shape. 356 T6 is the most common raw material.
