[時事閒聊] The difference between extruded aluminum profile and die-cast aluminum products

[複製網址]
In fact, the difference between them is very simple. From the appearance, the extruded aluminum profile is a long strip with a uniform cross section. Generally speaking, the cross section is sawed from any length, and the shape is the same. And if you look closely, you can see some fine extrusion lines.aluminum extrusion manufacturer For example, square tube, round tube, aluminum row, and angle aluminum are the simplest extruded aluminum profiles. Die-cast aluminum products do not have a fixed cross-section and shape. Die-cast aluminum products are molded, one by one, without sawing.

Let's take a look at the difference between these two processing methods. The extruded aluminum profile is heated to its critical point with a round aluminum rod and extruded by an extruder. Die-casting aluminum is made of aluminum ingots and alloy materials, which are melted in a furnace and enter the die-casting machine to form the mold. The shape of die-cast aluminum products can be designed like toys, with different shapes and convenient connection in various directions. In addition, it has high hardness and strength, and can be mixed with zinc to form a zinc-aluminum alloy. 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 instead of melting metal materials; aluminum alloy die-casting is a casting method. The metal materials must be melted first, and the molten aluminum alloy must be poured into the mold to cool and form and then take it out of the mold.
