High pressure die casting enables economical quantity production of castings at a rapid rate. These castings can comprise of various holes, screw threads, recesses, and are characterized by a high dimensional accuracy and good surface finish. They enable good economy of metal and require little or no surface finishing. The principal on which pressure die casting is based, consists of forcing molten metal into a mold or the die, under considerable pressure.

Die Casting Aluminum products are of great use in various industry sectors and more so in the aerospace industry where precision and high quality products is of utmost importance. These products are used in building both small as well as the major components in the aviation industry. Further, Aluminum Casting parts are used both in the commercial as well as pivotal military sector. The reason for this is simple - they are cost-effective solutions and offer great results.

Apart from being cost effective, the components made from die casting aluminum are additionally prepared to endure harsh weather conditions and increased damages. Another most important reason for using aluminum products in aircraft is that the metal is comparatively cheaper than other metals that are die casted. Moreover, aluminum has the potential to gel with other metals in order to offer durability and much flexible.

With aluminum casted products, you do not have to compromise on the quality yet can them at much cheaper production cost. In addition, all the standards that have been set for using of metal components, aluminum satisfy the need to the utmost. Hence, they are certified safe for use in planes, cost effective and have all the qualities that are required for flying crafts, so Casting Aluminum is on the rise like never before. In addition, the best thing about an aluminum die cast part is that its weight is favorable for the aircraft operations.

So, how exactly is Casting Aluminum done and what are the processes involved? Well, the answer is simple. Aluminum alloy is first forced into a high-grade steel tool at high speed and pressure in a high temperature. This results in superior quality products that are extremely light and thin walled ideal for use as aircraft components.

It is to be mentioned here that Aluminum Casting is a complex method. Only a really experienced and high skilled team of engineers can ensure that the components come with high volumes or with better tolerances and surface finish. In fact, this type of pressure casting is far more popular than gravity die casting or sand casting. This is because the need for machining in this method whether for aluminum or Zinc Casting is very low due to the close casting tolerances. Though the tooling costs in Casting Aluminum or rather any metal are considerably higher than the other two methods yet, the mechanical properties achieved thus are far better in terms of functionality.

Another development in high pressure die casting is vacuum die casting. It produces castings which have an even better finish than ordinary high pressure castings. There are two systems, the die is either enclosed in a hood which evacuates the air, or the holding furnace is installed under the casting machine, so that on the evacuation of the air from the die, the metal is sucked into the die and is compacted in it, and a process for making iron castings based on this principle has been developed.
