How Do Aluminum Enclosures Differentiate Between Die-Cast Aluminum And Extruded Aluminum?

The aluminum enclosure is stamped with aluminum alloy material, which has the characteristics of good ductility, low density, electrical conductivity, heat transfer, corrosion resistance, beautiful appearance, etc. It is widely used in instruments, meters, electronics, communications, automation, sensors, smart cards, industrial Control, machinery and other industries. So how do aluminum project box distinguish between die-cast aluminum and extruded aluminum?

How to distinguish between die-cast aluminum and extruded aluminum?

The principle of extrusion is to apply pressure to the aluminum rod in the extrusion cylinder, so that the aluminum rod close to the melting point is extruded into the shape of the die hole through the die hole of the die. Therefore, the extruded aluminum profile is equivalent to the extension of a two-dimensional plane. In theory, this plane can be extended infinitely. However, due to the limitation of the length of the equipment, the later operation of the long material is difficult, and the extruded aluminum profile is generally not more than 6 meters long. Then cut according to the actual size used.

The principle of die casting is to completely melt the aluminum alloy and then inject it into the three-dimensional aluminum enclosure mold, and maintain a certain pressure. After cooling, the mold is opened, and a die-cast aluminum alloy enclosure is completed. Die-cast extruded aluminium enclosure has a wider variety of appearances. 

It can be seen from the above that the extruded aluminum project box can only change its shape in a two-dimensional cross-section, while the die-cast aluminum enclosure can change its shape in any part in three dimensions. Die-cast aluminum can be made into a hollow ball, while extruded aluminum can only be made into a hollow round tube, and its two ends are open. Therefore, both ends of the extruded aluminum casing will be sealed with a cover or an aluminum plate. The die-cast aluminum housing can be made into a box shape and covered with a cover plate. But our extruded aluminum profile enclosures are still more common than die-cast aluminum enclosures. Why?

Because the die-casting aluminum mold is expensive, and the production efficiency is not as good as the extrusion aluminum profile, the processing cost is also relatively high. Die-cast aluminum housings are required in some cases where a waterproof seal is required. 

The above information on how to distinguish between die-casting aluminum and extruded aluminum is shared here. I hope this article can be helpful to everyone. If there is anything you don't understand, you can leave a message to the editor and we will answer you as soon as possible.
