Die cast aluminum is a kind of aluminum wherein metals are molted under high pressure in the mold cavities. In the die casting process, the metals are hardened and the desired shapes are produced. Aluminum die casting can be made with the use of either hot chamber or cold chamber process.
Aluminum die casting is considered as a non expendable technique which can be repeatedly used to produce different shapes, sizes and thickness of die cast aluminum. The die casting process can produce variety of shapes with accuracy and attractiveness.
Aluminum die casting is now considered as an industrial procedure for the purpose of creating aluminum for sale or made as part of machines or any other commercial or industrial production. This is now the easiest process since aluminum is melted in the designated molds to produce the desired size, shape and thickness. This process is essential in creating metal parts with specified details and quality.
In aluminum die casting process, metals are molten in the cavities of steel molds using high pressure technique. Aluminum die casting can be done in a single or multiple cavities, unit die or a combination of dies depending on what is to be produced.
Before, aluminum die casting is done using a low pressure injection. However, recently die casting using high pressure is common as it can squeeze die cast aluminum to the desires sizes and shapes.
To produce smooth casting, the metal that is molted is injected under both high pressure and speed. The high pressure is maintained until the metal becomes solid. Once it is hardened, the die cast is opened for the purpose of removing the metal casted.
Aluminum manufacturers used many variations to produce the specified results. They can use any of the following: squeeze casting or semi solid molding. In squeeze molding, the molten metal is cast without any gas entrapment or turbulence using high pressure for the purpose of achieving the high quality results, dense as well as the treatable components of the materials. On the other hand, in semi solid molding, the metal billets are being casted for the purpose of producing heat treatable aluminum castings with low consistency.
With the advent of modern technology, more sophisticated machines are now used to have consistent quality control. Either cold chamber or hot chamber methods can be used for aluminum die casting. Aluminum die casting is the biggest die casting technique used nowadays to produce commercial, consumer and industrial products salable in the markets today.
Aluminum die casting is proven as beneficial to industrial products. In this process, there are various modifications that can be made on the production. Manufacturers spend less and incur less cost and less time in the making of the produced aluminum which are more attractive to the eyes of the buyers.
Aluminum die casting can totally eliminate post machining and repeated molding. This process is very economical and finished products made under this process are accurate and long lasting.
