    Aluminum Castings Heat Treatment 

    Heat Treatment is one method used to improve the mechanical and physical properties of an aluminum casting. Heat Treatment consists of the heating and cooling of a casting in a controlled and specified manner, which does not change or affect the shape of a casting. Heat Treatment not only improves the strength, hardness and electrical conductivity of an aluminum casting but it also helps to improve other manufacturing processes such as machining. Heat Treatment must be conducted in properly designed furnaces that provide the internal thermal conditions and temperature controls to meet strictly specified guidelines and controls.  

    The Stages of Heat Treating Aluminum Castings: 

    Solution Heat Treatment - consists of heating an aluminum alloy casting to a high temperature for a desired amount of time. After the casting is heated to a high temperature it is rapidly quenched, by immersing the entire casting in a water or water glycol solution. This process is usually done to increase the strength of a casting

    Artificially Aging Aluminum Castings ?consists of heating an alloy for an extended amount of time. During the Artificial Aging process the castings are heated for a specified period of time but to a much lower temperature ten the Solution Heat Treatment process. By maintaining the heating process for an extended amount of time the grain structure is refined, producing much greater strength properties of the castings. Artificial Aging is used to create a harder casting. The Artificial Aging speeds up the process of aging of a casting that would normally occur naturally over several years.

    Semi-Permanent Mold Aluminum Castings

    The Semi-Permanent Mold Casting process uses the same general procedures as Permanent Mold Casting but in this process expendable cores of sand or other materials are added to the molding process to create a desired shape or an internal passage. In many cases, the practicality of having a solid casting does not exist. Many customers require that a product have passageways for materials to flow through; therefore a method of creating such passageways must be incorporated. In Semi-Permanent Mold Castings a pre-formed core is inserted into the Permanent Mold cavity. The metal flows around the insert and creates the desired shape or passageway. By using a sand core it allows for the easy removal of the insert to create the desired effect
