    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.

      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.

      @@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.

    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.

    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.

      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
      @CB-ck9dg ปีที่แล้ว +1

      @@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.

    why extruded aluminum heat sinks are so expensive? If the process is so simple, then heat sinks should not cost so much.

      Yeah, you only need precision machined die and 15000 ton press. If you want accurate dimensions for the extruded material, you need to keep replacing the die pretty often and those may cost 30000-50000 USD per part.

    So it's actually pretty similar to forged aluminum

    That isn't aluminum at 5:13. Kinda makes me wonder what other parts of the video are just plain false.

    Yet another video that fails to explain how little "holes" in the profile cross section are made, e.g. like shown at 5:05.

    How the hell do they make these extrusions hollow inside?!? The die would have to have bits floating in mid air 🤷‍♂️🤷‍♂️🤷‍♂️

    I still don’t understand how they make extrusions with multiple holes in them thats not in the center. The die would have to have the negative of said hole suspended with no supports. If there were supports it couldn’t make the holes lol 🤯

    They are squeezed thru a die and extruded-just like canned cheese spread! One of my friends that I help restore Pre-WWI motorcycles with worked his entire working life doing this very thing-making aluminum extrusions they made aluminum storm doors and replacement windows from, rat cheer in Tussa, Okra-Homer. Another friend worked at Spirt AeroSystems making aircraft extrusions-he got paid quite a bit more!!! He didn't do only aluminum!

    The mistakes in the narration are pretty Chinglish kinds of mistakes. Obviously there is nobody from the west actually being paid to edit or review this "Made for the West" video. Degrees is not the same as zeros. In addition a few technical terms were utterly skipped which were important and should have been included. I keep seeing videos like this where the Chinese are throwing resources, money, and people at things and consuming all of those things, and yet have not the first understanding of how any of it works or why it works. Emulation is flattery to us, but emulation is not the same as knowledge or brilliance.

    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.
