How are Aluminum Extrusions Made?

[@elFulberto]

This voice has all the energy and charisma of that 90s educational video on turning spheres inside out.

[@UncleKennysPlace]

Robovoices suck; I _never_ subscribe to a channel without human narration.

[@davidswanson5669]

You didn’t answer the biggest mystery that most people wonder about. How do you get holes from an extrusion process?

[@Thorhian]

They use multiple dies from what I know.

[@electricburning]

Core bars

[@glauroo.junior83]

The extrusion die is made of two pieces. The front part forms the external surface, then there is a mandrel that forms "the hollow part" behind the die. This mandrel is held to the front part by a "spider" with four arms. What intrigues most of the people is that, during extrusion, the billet metal is "cut" by the "spider arms" , but because of the temperature, pressure and the fact that the die chamber is sealed against oxygen, the metal welds back forming a hollow profile. This is suitable for architectural profiles, but for aeronautic purposes or high strenght alloys, for instance, seamless extrusion is applied.

[@electricburning]

@@glauroo.junior83 wow thanks!

[@davidswanson5669]

@@glauroo.junior83 why couldn’t you have made this video. You would have done a great job.

[@glauroo.junior83]

Nice presentation. If I can make a remark (I worked as a metallurgist in extrusion plants for 23 years), in the minute 3:05 they mentioned extrusion forces over 15,000 tons. A press capable of this force is a monster; the largest press I've ever seen was a 10,000 ton extrusion force, whose billet was 40 inches (1 meter) diameter. Usual press sizes for day to day production range from 1400 to 2500 tons.

[@alexwood5425]

And, pressure is not measured in tonnes.

[@Eduardo_Espinoza]

How are they able to "spray" an 0 with support material holding the center of the 0?

[@jpcaretta8847]

​@@alexwood5425 In the US they are confused because they still use garbage inch, pound, galon....

[@MarcoTedaldi]

​@@Eduardo_Espinoza look at 1:23. The holes in the dies are not cylindrical. So basically the aluminium flows around the core trough holes and gets compressed into the final shape only at the outlet.

[@RetroTinkerer]

​@@MarcoTedaldi so there is support material at the entrance of the material and up to a point but not all the way to the exit, the aluminum is soft enough and fill in the supports once it passes? Nice, I always had that doubt 😅

[@RaquelFoster]

1:45 If you're going to make videos by feeding text into a speech engine, you need to type out "degrees celsius" 🤣

At 4:55 it should state "temper" not temperature. T5 and T6 are the most common tempers for aluminum, although that is debate able and alloy dependent.

[@sabrekai8706]

I worked as a millwright in the end 80s, early 90s. Helped install machinery in a working extrusion plant. it was very interesting to see the process.

Good to know you like this video!

[@tymz-r-achangin]

Finally! A nicely done video that actually describes and shows detail, and there was no stupid music edited into the video. Thank you

[@christiankrippenstapel4336]

Nice! But how are hollow profiles made? How are the cores of the die fastened? Do they remain in the core of the product and were removed after the extrusion?

[@EaglePicking]

They're pressed through, just like in the video.

[@Nonononono_Ohno]

@@EaglePicking That still doesn't explain how the cores are fastened, if that happens at all. For very small "holes" in the profile cross section, like shown at 5:33, you would either need very thin and very long steel bars to fit into these holes while extruding (and afterwards, they would need to be removed, which is what @christiankrippenstapel4336 had asked: how do they get removed?), *or* the aluminum needs to flow around a construction in the die, in which case the aluminum would need to weld itself together again, right after the extrusion. So, how is it done?

[@EaglePicking]

@@Nonononono_Ohno When the aluminum is hot enough and the pressure is high enough, it just flows together again.

[@Nonononono_Ohno]

@@EaglePicking I see, thank you!

[@gatti5002]

we here over in the old world use the same process for aluminium , works fine !

[@islam56898]

This is the best presentation i was looking for

[@alextsitovich9800]

Hollow shape extrusion 0:55 - 0:58, 1:07 left - the both dies, 1:09 the both dies, others up to 1:27 are only first inner dies. We look at them from the exit of aluminium details. It would be great to see the die and corresponding resulting aluminium shape side by side. As I understand, the idea is to have a support for the central part in the first die and this part is as long as the second further final die. So, inner shape of aluminium is made by the first long die and the outer shape is made by the second short die; the both dies end approximately at the same cross-section.

[@snoopsnet8150]

Ahhh!!!! So the Aluminum "re-combines" after passing the support arms of the internal shapes! Thank you SO MUCH for helping explain that. ❤️ I've been using extrusion for engineering design for years, and it always bothered the hell out of me not knowing how they managed that without having parts of the die floating in mid air!!

[@curtisnewton895]

how does it work for hollow profiles ?

[@JerryDSM]

As a commercial Glazier I now understand completely how the products that I install are produced.

[@michiellombaers3198]

Some 45 y/ago I worked a summer job in such a factory. Good memories.

[@CB-ck9dg]

It would be nice if people in charge of editing the voice over to a technical or scientific video started to appreciate the difference between force and pressure. Saying 15,000 ton PRESSURE is very much wrong. How are kids and the general public supposed to learn from such badly written material? Force is force, pressure is FORCE PER UNIT AREA - a very different thing. Please stop it.

[@MikkoRantalainen]

Press is typically rated by tons it can push in linear direction. Technically, you should use kN (kilonewton) instead but that's rarely done in practice. However, you are absolutely sure that the pressure during the extrusion depends on the surface that force is applied.

[@CB-ck9dg]

@@MikkoRantalainen Well, I know they should use the N SI unit, if they really wanted to speak by the book. However, tons does not bother me at all, but for the fact that there are short, metric and long tons, which can be confusing. A kN, that's about 0.098 metric tons (or about a couple of hundredweight) which may still be adequate to express the force of a press.They all are force units, though a bit of a mess, but still all of them force units. Anyway. But these people speak of a FORCE (N, ton, kN, have your pick) as if it were a PRESSURE (Pa, bars, PSI, and what else). Force, alleged to be the same thing as a pressure. My dear God. I think they need to go back to their birthplace, be born over again, attend school at least up to the ninth grade, and be tought their Physics over again

[@joeflyer1]

I appreciate the video. However, the narrator stated "15,000 pounds of pressure," which is incorrect. It is force, not pressure.

[@RAPIDDIRECT]

Thanks for pointing out. I will confirm it with our engineers.

[@girthiusmaximius8486]

4:00, Certain types of Aluminum alloy such as the 6000 variants, Do not use water quenching for the process. Certain types of aluminum alloy are rich in magnesium and other metals that are actually very vulnerable to water, Causing marking and a unqiue type of corrosion that dull the metal. Processes without water use air cooling through the puller/strecher process. This drops the metal down to 120-90oF where it can be saftley handled for racking to be placed into furnaces. T5-T6 require a cook time of six and a half hours where T52 require only two and a half. T4 is a special type of aluminum extrusion where it does not require and heat treatment at all.

Первая поддерживает внутреннюю фильеры, а вторая затем закрывает всю внешнюю часть круга, за исключением пары миллиметров вокруг этой выступающей внутренней части.

[@MikkoRantalainen]

The die is a 3D object so it can have pathways connecting the hollow center to the sides - only the exit hole matters for the final extruded shape. Aluminium will flow around the support structures with enough pressure.

[@pauls5745]

multi step process with pieces of finite length. sort of forcing heated material over a mandrel, then thru a die for the outer surface shape

For being both an informative video and an ad for Rapid Direct it sure does cheap out on labor given the generated speech and the complete lack of quality control, and doesn't help that some of the images are poorly up scaled JPEGs blatantly taken from the internet. Also, the image for indirect extrusion and the explanation given are contradictory to each other. The image states that the die moves into the billet, while the narration states that the die is stationary and that it is the whole billet holder that moves against the die. Ending the video with "Rapid Direct gives you the best aluminum extrusion services, including expert advice and recommendations." isn't something this video showcases. If anything, cutting down on proper narration and a basic QC pass on a sub 10 minute long video used for marketing is a bad business decision. Any company cutting such generally cheap corners isn't a company I want to work with. Now yes, the video is still good overall, but the glaring issues doesn't paint a good picture of the company's practices.
