Factors Affecting the Aluminum Casting Process. Since Aluminum is one of the very few metals which can be used in almost any type of metal casting processes, the selection of the process to use is then based on two factors. The first factor being feasibility and cost and the other one is quality.
On the feasibility factor, aluminum alloy casting may be done by way of any of the available methods of metal casting. Aluminum casting process is easier to choose since this metal can be used in all processes. On some of these metal casting processes however, design feature as well as dimensions are the best determinants of the best method for casting. For instance, with metal molds weighing between 10 to 100 as much as the castings used when manufacturing, most huge cast products are done as sand casting instead of die casting or permanent mold casting. For smaller castings though, metal molds are used which ensures accuracy of dimensions.
The quality factor is also quite important in the aluminum casting process to be used. Quality in aluminum casting processes refers to the mechanical properties’ levels and the degree of soundness of the casting. The former refers to properties of ductility and strength and the latter refers to the absence of porosity, surface imperfections as well as cracking of the aluminum cast parts. It is however, especially with die casting, to completely eliminate porosity despite high cooling rates because air still tends to be trapped. This results into a small amount of porosity located at the center of the casting product.
