GRAVITY CASTING
Gravity casting is usually a manual process using ladles of molten aluminum alloy metal. However, for certain high-volume applications, it is also possible to use automatic ladle casting of molten aluminum alloy metal.

SAND CASTING
The economic effect is excellent: sand casting is hand operation, workers need many years of casting experience, the mold cost is low,the casting unit price is relatively high, suitable for large size, small quantity of production.

LOW PRESSURE CASTING
Low pressure casting refers to a casting method in which the mold is generally placed above a sealed crucible, and compressed air is introduced into the crucible to create low pressure on the surface of the molten metal, causing the metal liquid to rise from the riser to fill the mold and control solidification.
