Aluminium Extrusion - An Inside The Machine View Of The Aluminium Extrusion Process

- The Aluminium Extrusion process is fairly simple - heating aluminium logs (or billets) and feeding the heated aluminium through steel templates (Dies) to create a desired shape. It’s a similar process to a childs toy - pushing wooden shapes into the correct holes.
But have you ever wondered what the aluminium extrusion process looks like from inside the machine? In this video, we demonstrate the entire aluminium extrusion process digitally, allowing you to see the whole process from the aluminiums point-of-view.
Interested in seeing the aluminium extrusion process from inside a working aluminium plant?
An additional video of the aluminium extrusion process from one of Norsk Hydro’s plants can be seen here: • How Is Aluminium Extru...

Thank you for showing how a pair of dies are used together to produce a hollow cross-section of extruded material.
Only one die, one is called a bolster and it's mostly used to support the great force exerted on the die
@@THOR252RACER OK, thanks!
That's exactly what I wanted to see. Thanks! Wasn't sure how AL profiles are made.
Coming from someone who has both ran an extrusion press and also works on and corrects aluminum extrusion dies, I found this quite fascinating to watch as almost the entire video correlates very similar to the job I do/did. Awesome job
I’m currently a student in an engineering program for high school and was wondering how a hollow extrusion could be manufactured. Wouldn’t you need a floating bit in the die, like shown in the video? How does that work?
@@daanthill4112 good question.
For the direct extrusion method, which is the same method shown in the video, we can extrude a hollow shape profile with a two or three piece die similar to the one in the video. The desired profile specs is ultimately what determines die design, but with a two or three piece “combo die” as I call them, the mandrel creates your ID profile while your cap (middle piece) creates your OD profile. The third piece, if the die has one, is typically just reinforcement steel known as a “backer”.
Any other questions feel free to ask away man. I’m currently a draftsman so I can atleast do my best to answer any.
Very informative, thanks.
Perfect
Thanks a lot very helpful! Even my non engineering bro understood it easily
Was briefly wondering how they're made, now I can get back to more general procrastination
I get how an opensided shape is extruded, but how are closed/hollow shapes done without a seam? Since this was a cutaway, I don't see how it works.
great！
By the topology of profile does the aluminum cold welded inside die to create tube ?
Can you extrude a round shape over another smaller round extrusion ?
What would be the cost of such an extrusion? What about the price difference between the states and europe? Little do I know about that stuff but it looks amazing and I am highly curious. Have a nice day! :)
Much cheaper than milling it.
Is it possible to build small machine for Aluminium Extrusion?
What happens to all the material that isn't pushed through the die?
some is cut off (usually full of impurities) the rest stays in the die and is pushed through when the next billet comes
The small cylinder (log) is extruded into a 6 meters long shape ?
Shape long depends on area of profile drawing. Therefore length of shape may by variable from 3 to 7 meters usually
@@alexey82tarasov mmmh no... Usually is a lot more long it can be 30 meters too
@@Pr0ject95 I said about length of shape from small cylinder (0:44 for example).
Well that's one mystery solved.
Name of the software???
Hey
czcams.com/video/pXQ0zCnA4Lk/video.html
Can stainless steel profile be extruded kindly let us know
dépend du type d'acier
No.
No
Good luck good
The extrusion temperature is room temperature ?
defenitely not
about 670 Kelvin
@@vmarek98 what about in a normal measure of temperature?
@@nottsninja maybe he lives in a physical laboratory?!
@@nottsninja 0 Kelvin is absolute zero which is about -273 degC. So, 670 kelvin is about 397 degC
Do shrinkage allowance considers in extrusion molding?
probably
Assolutamente no si vede chiaramente nel video
@@niccolotani6828 in che senso?
1mm per metre expansion and contraction
