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

In fact, the difference between them is very simple. From the perspective of appearance, the extruded aluminum profile is a long strip with a uniform cross-section. Generally speaking, it is sawed from any length of its cross-section, and the shape is the same. And if you look closely, you can see some fine extrusion lines. Such as square tube, round tube, aluminum row, angle aluminum, these are the simplest extruded aluminum profiles. While die-casting aluminum products do not have a fixed section and shape, die-casting aluminum products are cast, one by one, without sawing.
Let's take a look at the difference between these two processing methods. The extruded aluminum profile is extruded by a round aluminum rod heated to its critical point and then extruded by an extruder. Die-cast aluminum is made of aluminum ingots and alloy materials, which are melted in a furnace and formed in a die-casting machine. The shape of die-casting aluminum products can be designed like toys, with different shapes, which are convenient for connection in various directions. In addition, it has high hardness and strength, and can be mixed with zinc to form zinc-aluminum alloys. The cost of die-casting aluminum product molds is much higher than that of extruded aluminum profile molds, and it is not easy to repair the mold if the size design is different.
To sum up, extruded aluminum profiles use mechanical processing methods without melting metal materials; aluminum alloy die-casting is a casting method. The metal materials must be melted first, and the molten aluminum alloys must be injected into the mold to cool and form, and then take out from the mold.
