Producing Aluminum Part Castings with Die Casting. Aluminum part castings can be made using a variety of casting processes, but the most extensively used among all these is the die casting process. Basically, aluminum die casting parts are made by injecting molten aluminum metal into metal molds or dies. Substantial pressure is needed; rapid injection plus rapid solidification are all combined in order to produce fine-grain, notably dense surface structures. These features lead to impressive wear and fatigue properties, making aluminum cast parts highly collectable. It is important that great care be exercised because incidents of shrinkage and air entrapment may occur, leading to porosity and damage in costs.
The die casting process or aluminum casting process is known to produce parts that are not easily heat-treated or welded due to entrapped gases. Thus, aluminum part castings made with die casting are typically not heat-treated but, on most occasions, are only given metallurgical as well as dimensional treatments for their necessary stabilization. To protect parts for certain special applications, manufacturers often use a form of vacuum for cavity venting. Moreover, special techniques are employed during production to deal with pressure-tight parts. Aluminum alloys that carry narrow freezing ranges are ideal.
Speaking of alloys, aluminum part castings of the best quality are those made from the family of aluminum-silicon-copper alloys. This family offers an excellent combination of strength, fluidity, corrosion resistance, freedom from hot shortness, and cost. Today, at least 85% of die castings made from aluminum alloys come from the said family, proving its ability to match every industrial business’ needs.
