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.
Process : Aluminium gravity castingMaterial : aluminiumMachine : die-machine ranging from 250T to 1600TUsed for : Engine blocks and manifolds, machine bases, gears, pulleys
