Aluminum extrusion has seen a substantial rise in application in product design and manufacture over the past few decades. A recent tech naïve analysis projects that the worldwide aluminum extrusion market will expand at a compound annual growth rate (CAGR) of about 4% between 2019 and 2023.
Perhaps this manufacturing procedure has come to your attention, and you’re curious about what it is and how it functions. We’ll talk about aluminum extrusion today, including what it is, what it can do for you, and how it works. The first and most important question is what we’ll start with.
What Are Custom Aluminum Extrusions?
It is the process of molding specified component forms out of aluminum billet (logs), which are heated until they are flexible. Aluminum is a superb choice because of its lightweight and adaptability, even though any metal may be extruded.
As a result, numerous sectors, including the production of automobiles and buildings, now favor it as their preferred metal. Particularly extruded aluminum is frequently utilized in structural applications due to its ease of bending without sacrificing strength or longevity.
The Importance Of Custom Aluminum Extrusion
Extrusion production requires precision. The last thing you want is to find out the measurements are incorrect after purchasing tonnes of merchandise. It is a great choice to work with an organization like Ugaaluminium Custom Aluminum Extrusion Profile Services which will walk you through the process. Several distinct variables influence the extrusion process. While there are generic templates available, if your product requires a highly precise form and size, it is preferable to have custom-made work done.
These aluminum extrusions are produced by pushing hot, liquid aluminum through a steel die. Consider the die to be a mold. A unique die must initially be made for the desired aluminum forms. Aluminum can be machined with more precision but at a higher cost. Depending on the use, the aluminum may also require extra finishing or heat treatment to ensure its strength. The use for which you’ll be employing these extrusions will, of course, completely determine how precise the specs need to be.
Additionally, aluminum may be extruded in two different ways. It’s kind of self-explanatory how hot-heading and cold-heading work. When aluminum heat to a very particular temperature (often 25% below the melting point) and force through the die, this process is known as hot heading. Similar to hot heading, you do cold heading at ambient temperatures. Despite the Pros and Disadvantages of each approach, hot heading is a quick process, but cold heading provides good results.
Aluminum Extrusion Process in 10 Steps
Ten steps make up the aluminum extrusion procedure. We’ll look at what they are now:
Step #1: Extrusion Prepared Die is Transferred to Extrusion Press
First, you manufacture H13 steel die in the shape of a circle. Alternatively, if one is already on hand, you take it out of a warehouse. Heat the die between 450 and 500 degrees Celsius before extrusion to maximize die life and maintain equal custom metal stamping flow. Then you should insert it into the extrusion press after heating up.
Step #2: Heating an Aluminum Billet Before Extrusion
The next step involves cutting a lengthier log of alloy material into a solid, cylindrical block of an aluminum alloy known as a billet. You prepare it in an oven like this one at 400 to 500 degrees Celsius. As a result, it becomes sufficiently pliable for extrusion but is not molten.
Step #3: The Billet is Moved to the Extrusion Press
In the third step, you mechanize the billet from the preheating chamber to the extrusion press after heating. A lubricant (or release agent) add before it is put into the press. Thus, to enhance the protection against the billet and ram sticking together, apply the release agent to the extrusion ram.
Step #4: The Ram Forcefully Pushes the Billet Material Into the Container
The malleable billet is now put into the extrusion press, where the hydraulic ram exerts a pressure of up to 15,000 tonnes on it. Thus, the extrusion press’s container fills with the billet material as the ram exerts pressure on it. The substance enlarges to fill the container’s walls.
Step #5: Die, Extruded Material Emerges
The alloy material force against the extrusion die as it fills the container. The aluminum substance is always under pressure, and the only way it may escape is through the die’s opening(s). It pops out of the die’s aperture as a completely formed profile.
Step #6: Quenching Extrusions after Guiding Them Along The Runout Table
A puller grabs the extrusion as it emerges from the press and moves it down the runout table at a speed corresponding to its escape from the press. The profile is “quenched,” or evenly cooled, as it goes down the runout table by a water bath or fans above it.
Step #7: Shearing Extrusions to Table Length
Then you use a hot saw to shear an extrusion after getting the entire length of the table to remove it from the extrusion operation. Temperature is crucial at every stage of the procedure. Even though the extrusion was quenched after leaving the press, thus, it didn’t cool completely.
Step #8: Cool Extrusions to Room Temperature
Table-length extrusions that have undergone shearing mechanically from the moves runout table to a cooling table. The profiles will stay there until they warm up. When they do, they must be stretched.
Step #9: Aligning Extrusions by Stretching on the Stretcher
It is necessary to repair some natural bending in the profiles. They transfer on a stretcher to rectify this. Once it is completely straight and you get into the specification, you grasp each profile mechanically at both ends and pulled.
Step #10: Extrusions are Sent to the Finish Saw and Cut to length.
Table-length extrusions move to the saw table after they are straight and work hard. Then you saw them in the preferable lengths, typically between 8 and 21 feet long here. The extrusions’ characteristics now match those of the T4 temper. Thus, you can place them in an ageing oven after sawing and ageing to the T5 or T6 temper.
