What is Aluminum Extrusion?
Before going in-depth about “Aluminum Extrusion Manufacturer – Aluminum Extrusion Manufacturer in China”, let’s discuss Aluminum Extrusion.
Aluminum extrusion manufacturing
Extrusion is a process in which the aluminum alloy material passes through Aluminium Extrusion Dies along with a special cross-sectional profile, using a powerful ram. Then, this aluminum comes out through the opening. Now, it holds the shape of the die. After that, it pulled out along with the runout table. At this point, the aluminum extrusion process is comparably simple as squeezing toothpaste. As toothpaste comes out from the tube by applying some pressure, it takes on the shape of the opening of the tube. Similarly, aluminum comes out in the shape of a die. The Aluminum Extrusion Dies types as usually available in angles, channels, and round tubes.
Types of Aluminum Extrusion
Depending on the process, aluminum extrusion is classified into two types, such as;
- Direct Extrusion
- Indirect Extrusion
1. Direct Extrusion
It is the simplest production mode for aluminum extrusion. In this process, the die remains stationary. But the ram forces the billet through the die opening. During this process, both the billet and ram move in the forward direction. That is why, this process is also known as forward aluminum extrusion.
2. Indirect Extrusion
On the other hand, in indirect extrusion, the billet doesn’t move. While the assembly, present on the end of the ram, moves in the opposite direction of the billet. Due to this, the pressure develops, which is essential for the metal to flow through the die. This pressure helps in pressing the harder alloys and smaller cross-section products. Moreover, the lower pressure allows for a lower pressing temperature. Resultantly, it gives a greater extrusion speed and increases productivity.

The Process of Custom Aluminum Extrusion
The process of Aluminum Extrusion in China takes place in direct or indirect extrusion. Here the extrusion press available with several power levels, such as at Impol, are in the range of 12.5 to 55-MN. But before starting the extrusion process the cast aluminum rods required to be cut into small pieces. These pieces are known as billets. They decide that the length of each extruded bar will be the same. Consequently, the material will not get wasted.
Aluminum extrusion process
The aluminum extrusion process can be modified according to customer needs. Here, we discuss the six stages of aluminum extrusion.
Stage-01: Preheating of Aluminum Billet and Steel Die
In this stage, the billets are first heated in the gas furnace or induction. This temperature starts from room temperature and goes to extrusion temperature. Moreover, its range varies depending on the alloy and final temperature. From there on, the heated billets must be malleable, in this way, they can acquire the required shape. But they must be firm so, they can sustain the shape even during the transportation process. Then the push bat exerts pressure on these billets and allows them to move towards the die opening.
Stage-02: Loading of Billet into Extrusion Container
In the second stage, the heated billets, then quickly transfer to the Extrusion press container. Accordingly, they can prevent heat loss. At this stage, the billets are ready to be extruded. Afterward, the ram exerts pressure on them and pushes them towards the opening of the die.
Stage-03: Extrusion
After passing from the die opening, the billets get into the tool. These die openings can be changed and modified into several shapes and sizes. This stage is just like the cookie press. Here the shaped disc creates several cookie designs. Subsequently, the bars, with the required shape, come out of the press container.
Stage-04: Controlled cooling
Just after Extrusion, the quick cooling of bars, tubes, or profiles, takes place. Hereafter leaving the press, the full bars are then put into the water bath. It guarantees the uniform quenching of heated aluminum. Moreover, this quenching process is essential for the required mechanical properties and adequate microstructure. Thus, to eliminate any danger of material deformation, the cooling process is mandatory.
Stage-05: Stretching of the Bars
After cooling, the bars are cut into the required lengths. During the cutting process, the pullers grab them. These pullers are generally laid over the runout table. They allow the bars to cool down further. During this phase, the extruded bars go through the strengthening process. This process stretches them and removes the internal tension within the bars and ultimately ensures their mechanical properties.
Stage-06: Cutting and Final Packaging
This is the final stage of aluminum extrusion. In this phase, the strengthened bars are again cut to the required length, which is specified by the customer. So, the aluminum bars have temper T1/T4 properties. But, they need to be with T5/T6/T66 temper. Furthermore, this aging process again strengthens the bars/profiles or tubes, till they fulfill the mechanical properties of the specified alloy.
Applications of Aluminum Extrusion
Aluminum extrusion press manufacturers are at the forefront of technology, designing and shaping aluminum into detailed profiles. Their presses are the backbone of the extrusion process, enabling the transformation of aluminum billets into a myriad of shapes and sizes with precision and efficiency.
