Nowadays, Sand Casting is the most popular casting process there are many, many more processes available to the backyard foundries. However, die casting seems to be especially useful when dealing with aluminum and other light alloys. The basic idea behind this casting process is pretty much exactly what the name suggests. The metal is introduced into the mold by the force of gravity. Most other casting process either use natural pressure difference like the kind in certain sand casting procedures or they use forced pressure like in centrifugal casting to get the molten metal into the mold.
One of the most common uses for die casting is when permanent molds are going to be used. Also called a die, the permanent mold is really only economical for those planning on using the same mold numerous times and will need to keep the quality at a constant level. While some temporary molds can be repeatedly used the quality of the finished product will begin to suffer over time. With die molds the quality will remain the same. Die molds should be seen as an investment. Yes, they will be more costly then other molds; however they will outlast cheaper options for molds. With Permanent molds, they are created using cast iron, steel, and other metals. Die casting is used for the permanent mold process with pleasing results. Die casting is usually used when the finished product is more visually based then structurally based which is why this method is a favorite of artists and even some jewelers. The loss of strength is due to the lack of pressure used in this process. For those that need the strength but still want to use die casting, more of the molten metal will need to be used which will increase the weight.
