How Aluminum Cans are Made?

Ever wonder how an aluminum can is made? We have! ever since we can remember the coca-cola aluminum cans, which is a lot.
Well, aluminum cans are made with a lot of highly industrialized procedures as we see on this video; everything passes on so quickly and with deep quality care.
Evidently the aluminum alloy and procedures that we see on an aluminum foundry are very different, no wonder aluminum is a great versatile material.

Aluminum alloys are formed commonly with copper, zinc, manganese, silicon and magnesium as the alloying elements. This components help to give aluminum better properties, such as cost effectiveness due to the melting point.

There are many kinds of aluminum allow compositions, you can find a general description of aluminum alloys inthe matweb, you can find also some data about most used aluminum alloys in casting here.

Aluminum alloys are ideal for manufacturing a recyclable, light and stiff product, it is also very diverse in the forms that it can take thanks to processes as sand casting and permanent mold casting (described in previous posts) among other processes.

sand casting

There are two kinds of molding in sand casting, one is commonly known as green sand casting and the other is known as air set sand castings. Both methods work by packing the mixture around a master patter for forming the mold cavity, the pattern is removed from the cavity and the final mold is formed by two parts generally called the cope and drag. The molten aluminum is poured then into de mold, when its time the sand mold is destroyed, obtaining like this the aluminum product in its first phase.

Aluminum castings can be made with many different techniques that work for different purposes. For a low to middle sized production the most recommendable in order to have competitive costs while maintaining a high quality will be to use sand casting or a permanent mold casting.

Sand aluminum castings are ideal for a low production, it allows a quick manufacture maintaining a low budget, it also offers the possibility of having a versatility in the production process since it would be relatively easy to make a change on the printing model.

Permanent mold castings are much better for a middle range production, it offers a higher fidelity on the aluminum product or part and it is also much faster to manufacture than other methods, with this kind of casting you will get high quality and control over your aluminum products.
