The difference between extruded aluminum profiles and die-cast aluminum product

Industrial aluminum profiles

    In fact, the difference between them is very simple. From the shape, the extruded aluminum profile is a long strip with a uniform cross section. Generally speaking, it is sawed from any length and its shape is the same. And look carefully to see some fine squeezing lines. For example, square tube, round tube, aluminum row, and angle aluminum are the simplest extruded aluminum profiles. While die-cast aluminum products have no fixed cross-section and shape, die-cast aluminum products are cast, one by one, without sawing.

General aluminum profile

Let us look at the difference between the two processing methods. The extruded aluminum profile is extruded by an extruder with a round aluminum rod heated to its critical point. The die-cast aluminum is made of aluminum ingot and alloy material, melted in a furnace, and molded into a die-casting machine. The shape of die-cast aluminum products can be designed like imaged toys, with different shapes and convenient connection in various directions. In addition, it has high hardness and can be mixed with zinc to form zinc-aluminum alloy. The cost of die-cast aluminum products is much higher than that of extruded aluminum profiles, and it is not easy to repair if the size design is different.

Die-cast aluminum products

     To sum up, the extruded aluminum profile uses a mechanical processing method without melting the metal material; the aluminum alloy die casting is a casting method, and the molten metal alloy must be first melted into the mold to be cooled and formed, and then taken out from the mold.
