How Are Aluminium Profiles Made?

In making the aluminium profiles, you will use the aluminium extrusion method.

This is a process where you will force aluminium alloy materials through different dies with particular cross-sectional profiles.

To have a proper understanding, here is a step-by-step process that explains the aluminium extrusion process.

Step One: Preparation Of The Extrusion Die

First, you will prepare the extrusion die and then move it to the extrusion press.

You will use H13 steel to machine a round shaped die and then preheat it to about 450 to 500 degrees Celsius.

Heating the die will maximise its life and increase even flow of the metal before loading it to extrusion press.

After that, you will heat a solid aluminium alloy in an oven at temperatures ranging between 400 to 500 degrees Celsius.

It will make the materials malleable enough for the extrusion process even though it must not be melted.

Step Two: Extrusion Process

Aluminum profile extrusion

Aluminium profile extrusion

As soon as heating is complete, you will mechanically transfer it to the extrusion press.

You can apply a lubricant to the extrusion press to assist in loading and also act as a release agent.

In the extrusion press, a hydraulic ram will apply 15,000 tonnes of pressure thus pushing it further into the container.

The pushing force will expand the material thus filling the container walls and then pressed against the extrusion die.

The force will push the material out through the openings of the die thus emerging as a complete aluminium profile.

It will assume the shape of the container within the extrusion press.

Step Three: Quenching The Extrusions

At this point, you will use a puller which will guide the extrusion over a runout table.

As it glides over the runout table, the aluminium profile is quenched through cooling using water bath.

Apart from the water bath, you can also use cool air from fans operating above the runout table.

After that, you will shape the aluminium extrusion to table length by shearing using a hot saw.

Step Four: Cooling The Extrusion

You should note that quenching the aluminium extrusion does not cool it to the desired point.

Implying that, you will have to cool the aluminium extrusion to room temperature after shearing.

You will cool the aluminium profile on a cooling table and then left on the table to achieve room temperature.

Step Five: Stretching Aluminium Profile

In the final stages of the extrusion process, you will stretch the aluminium profiles into proper alignment.

Here, you will use the stretcher which will stretch and align the aluminium profile accordingly.

Finally, you will move it to the finish saw and then cut it to the right length before heat treatment.

What Is The Cost Of Aluminium Extrusion Die?

You should also understand that the cost of the aluminium extrusion die is very low.

In other words, the extrusion process of the aluminium profiles is inexpensive.

In case you are looking for aluminium extrusion dies with simple shapes; you will spend between 550 to 750 USD.

You might also opt for the hollow designs which will require 2-piece dies costing between 1250 and 1500 US dollars.

Apart from that, you may opt for the highly complicated designs which will cost you as much as 4999 US dollars.

How Does Drawn And Extruded Aluminium Compare?

You can choose between the drawn aluminium or the extruded aluminium depending on application specifications.

To make the right choice, you should understand the difference between the drawn aluminium and extruded aluminium.

The main difference between the two types of aluminium profiles is the mode of shaping using the die.

Extruded Aluminium

Extruded aluminium profiles involve pushing the materials through a die to get the shape that you desire.

In this case, you will determine the shape of the final product by determining the shape of the die.

Drawn Aluminium

On the other hand, you will make the drawn aluminium profiles by using different types of molds.

In this case, you will use the plastic deformation technique to make the drawn aluminium profiles.

You will, however, experience a hard time trying to determine the plasticity and flexibility of the drawn aluminium extrusion.

This is because the process does not involve stretching which will tear the aluminium to desired levels.

It os the best type of aluminium profile that you will use for making tins, pots, cand, among other circular objects.
