Different Types of Aluminum Cast Parts. The aluminum casting process is one that has become very popular over the last decade, although it has been around for numerous years now. The reason for this is plain: the aluminum casting process offers various benefits. In addition, the process can produce different types of aluminum cast parts, and just what these are we will be discussing in this article.
Basically, there are three aluminum casting methods, and they are die casting, sand casting, and gravity-fed casting. Die casting is most likely the well liked and the oldest of all three methods. It is also the method that manufactures aluminum cast parts that have the highest tolerance and the most unbelievable, fine finish. The process chiefly places pressure on the molten aluminum so that the die cast parts end up more intricate than other cast parts. Die casting is favored for the production of small to medium aluminum cast parts. Sand casting, in contrast, is suggested for the production of large aluminum cast parts that involve coarser surfaces. In contrast with die casting, the production costs (both pre and post) of sand casting are higher, but the tooling costs are lower. Finally, gravity-fed casting is regarded as an intermediate option. Therefore, it is suggested for the production of aluminum cast parts in all sizes. The polish or finish of aluminum part castings is as fine as that of the die casting process; the production costs are lower than those of the sand casting process; and the tooling costs are comparatively affordable or reasonable.
