A Closer Look into the Casting Process. The aluminum casting process has been around for a long time, and it operates by forcing molten metal, which is aluminum (naturally) under considerably high pressure into a variety of tooling cavities. The end result of this process, which actually takes longer than most people think, is a number of aluminum cast parts. Aluminum cast parts are some of the most coveted cast parts in the metalworking industry, and it is not hard to understand why. Aluminum part castings are unbelievably delicate and intricate in form, detail, and texture, allowing clients to make quality products.
So, what actually happens in the aluminum casting process? First things first – the mold is closed, just after it is sprayed with lubricants, and the cast parts are closely monitored in terms of pressure and temperature. The pressure required to shoot the molten metal into the die is around 10-175 mpa or, in other measurements, 1500-25000 psi. This pressure is maintained until, finally, the mold successfully 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 client’s taste and needs), such as tin, magnesium, lead, and zinc. Nevertheless, the aluminum casting process enjoys a vast market and claims one of the top spots in the list of the metalworking industry’s preferred casting processes. Die Cast Tooling.
