Put aluminum ingots and other raw materials into the melting furnace for heating and melting until the required temperature and chemical composition are achieved.During melting, refining treatments such as degassing and slag removal may be carried out to improve the quality of the molten aluminumPouring & Mold Filling
Manually pour the refined molten aluminum into the sprue of the metal mold using a ladle. The molten aluminum fills the mold cavity by its own weight.The pouring speed and volume must be properly controlled to avoid defects such as gas porosity and slag inclusionsVentilation
During the filling of molten aluminum, the gas inside the mold cavity needs to be discharged in a timely manner to ensure the quality of castings.Vent grooves, vent holes and other structures are usually arranged on the mold for gas exhausting.Cooling
The molten aluminum gradually cools and solidifies inside the mold.The cooling rate has a significant influence on the microstructure and mechanical properties of the casting, so it must be controlled according to the technical requirements of the castingMold Opening
When the casting has cooled to a certain extent and acquired sufficient strength, open the mold and take out the castingFettling
Clean the removed castings and remove surface burrs, flash, gate residues and other excess materialHeat Treatment
Appropriate heat treatment, such as annealing, quenching and aging, shall be carried out on the casting according to its service requirements to improve its mechanical propertiesMachining
