A Closer Look into the Aluminum Casting Process. The aluminum casting process has been around for several years, and it operates by forcing molten metal, which is aluminum (naturally) under very high pressure into a variety of tooling cavities. The end result of this process, which in fact takes longer than most people think, is a quantity of aluminum cast parts. Aluminum cast parts are some of the most in demand cast parts in the metalworking commerce, and it is not difficult to understand why. Aluminum part castings are incredibly delicate and intricate in form, detail, and texture, allowing customers to make quality products.
So, what truly happens in the aluminum casting process? First things first – the mold is closed, just after it is coated with oils, and the cast parts are closely watched in terms of pressure and temperature. The pressure needed to shoot the molten metal into the die is around 10-175 mpa or, in other measurements, 1500-25000 psi. This pressure is sustained until; finally, the mold effectively solidifies. To complete the aluminum casting process, the die is then filled with a high-pressure injection; this is repeated before the entire mold gets the chance to harden.
Aluminum is just one of the chosen metals that can be used in the casting process. Other casting process makes use of non-ferrous or ferrous metals (this all depends on the customer’s taste and needs), such as tin, magnesium, lead, and zinc. However, the aluminum casting process enjoys a huge market and claims one of the top spots in the list of the metalworking industry’s favorite casting processes.
