The only difference between the end of the slug and the rest of it are the ink stamped production numbers. they may even be from magnetic ink, in any case I suspect they use the fire to burn those away. Contamination.
1:40 -- the fire adds a layer of black soot to the end of the billet so it doesn't stick to the ram that pushes it into the extruder. Afterwards, the end with the soot is trimmed off so the next billet will seamlessly bond with it as more billet is pushed into the extruder. Otherwise, there will be a weak spot in the extrusion where the two billets will not bond.
I wondered if that soot acted as a release agent. I also wonder what length one lug can be extruded to alone. Fascinating process. And so many possibilities to get your hands sliced wide open without protection.
@@FaceFaceMan Yes, and as for the length, it will depend on the cross sectional area of the profile. These were pretty large profiles, so it takes multiple billets to make one length (not sure of the length, but it looked to be about 15 meters or roughly 50 feet).
The flame looks like oxy-acetylene set with excess fuel to make a carburizing/reducing flame. It will lay a bunch of carbon down. I am assuming it's on the face that the piston pushes on and it's to prevent adhesion of the aluminum to the face of the piston.
Ok smarties, then how do they get the 1/8” holes (4 of them) to exist inside the profile? Those holes extend the entire length of the extrusion (seemingly 100+ feet long).
@@davidswanson5669 they hang a mandrel in the middle of the part and the material flows around it and re-knits together. The quality of that junction is never as good as homogenous material and in some circumstances you can split the extrusion apart, which I have dealt with before on a part that REALLY, REALLY could not tolerate splitting.
@@paulsomero ok so the mandrel is relatively short and is placed somewhere near the extrusion die (if that’s what it’s called), as opposed to inserted into the entire length of the aluminum part (which is what I typically think of when I hear the word mandrel. I guess the soft nature of aluminum is why this is even possible - like play-dough, but yeah I can imagine the issues with integrity where it recombines. Makes me wonder if they could just create versions without the little holes, even if they cost and weigh more.
@@davidswanson5669 depends on application. I think that better setups have a longer chamber and more tonnage to provide more knit time, but don't quote me on that. Sometimes you need the holes, or you might have many complicated holes/walls and it can get pretty tricky. My part was a motorcycle frame member and our vendor had put the split in the worst possible place, but we luckily caught it and they fixed it before it became a real issue.
would need something to burn to create soot and if that was the issue a mechanic brush would work, i suspect they are burning off the chemicals in the production numbers printed on the end?
Sijingcheng is a large comprehensive aluminum profile enterprise that excels in the development, design, and production of advanced architectural, decorative, industrial aluminum profiles and aluminum extrusion profiles.
A mold is not used in this extrusion process. Aluminum is pushed through a "die", and that's what forms the intricate cross section. Dies are made from hardened tool steel. A wire EDM cuts the profile shape into the die. The extrusion process is similar to a Play-Doh toy, but with a lot more heat and pressure ;-)
They burn the end of the billet with acetylene to prevent the billet sticking with the main ram. It causes mechanical stress to ram head over time, thus causing more work and loss of time to change the ram head. Hope its helpful
I've always wondered this: How do they make the internal holes? I can understand pushing theough a die to get the outer shape, but the part of die that creates the inner holes would have to be floating in mid air 🤷♂️🤷♂️🤷♂️
Thanks for the video. I'v never understood how extrusions with hollows are made. How does the mandrel make the inside hole, it would have to be floating in mid air, and still have aluminium flow around it.
the mandrel(s) are held in place by ridges that connect them to the outside of the molds.. those ridges vanish towards the exit of the mold, so that the aluminium reconnects and forms a closed extruded shape without gaps in the profile.. it can do that because it's flowing into itself due o the heat.
Hi everyone, i have a question about aluminium straightening step. The aluminium profiles were just adjusted for straighness by the operator's eyes when using a straightening machine. So I think with each aluminium profile should have to suitable force to have the correct demensions. Please explain for me if you known it, thanks! (sorry my English not good ^^)
I worked at the Barry Road Campbelfield Alcan in Victoria Australia ( now Capral) back in the mid 80"s, this video looks exactly the same as what we worked with back then.
@@bezataye9084Puller don't run at same speed, the puller determines the size of extrusion the slow it runs the size gets bigger than the die cause metal is soft at that temperature if the puller runs to fast the extrusion tube gets smaller size. There is a PID controller to make it exactly needed size
The product they are making is commonly referred to as "80-20 extrusions". It's the backbone of a modular building system. There are thousands of connection pieces that allow one to make anything from a picture frame to a CNC machine with this system. Another great video by the way...Thank You!
No, oxidation wouldn’t be a problem because a few seconds later the end is chopped off anyway. Each end is black and covered in soot from the brief shot of dirty flame. Stops the piston sticking to the billet apparently.
they sell the bamboos for such too but no one makes the nice tent connectors with the 6 ways and 5ways 4ways parts in aluminums you guys should make for such geodomes to make greenhouses
paint end poles A and B at ends the two colours to show different sizes sell them but needs aluminum 6 way connectors and 5 ways connectors as no one sells in north amrica except steel heavy but needs aluminum lighter poles too for green houses etc
One of the things that is rarly shown, so rare u never get to see it lol, is how do they make a hollow square shape without breaks in it? I mean when u think about it, there is a die that they press the metal thru like you did with playdoe or clay as a kid. there has to be a big piece of the die in the center to force it into a thin wall as the metal flows around it. but u CAN'T just have the metal floating there, it has to be supported by the die on the other side of that wall (otherwise its using magic). so this means that at least one of the 4 side walls has to be split in two. How do they get those back together??? you can see how when they make a round hollow pipe, they bend the flat steel into a tube and then weld the gap, but how do they do that in an extruder?? this is the big mystery
They have 2 separate dies in front of each other. One is the outer and one is the inner. Then as the metal gets pushed through it bonds back with itself.
I don't know for certain why they use the flame on the end of the billet but my best guess is that it's acetylene without oxygen to make carbon soot. Carbon like that is a very good lubricant and mold release.
Hey, where is the part when the actual extrusion takes place? How does the sliced aluminium rods get transformed into the long profiles . That's the heart of the process, but not shown 😂
Did you not see the whole end sliced off before processing? Soot is added via the smokey flame, note how black those ends are, to stop the piston from sticking to the ram apparently.
Why do they heat by flame ? Coil electromagnetic field heating in Y-axis is more effective, so heat up to equivalent molecular level by high intensity flame X axis , trim another end side off.
Make 12 foots for 2 to 5$ a pole please then tell homedepot sell for reasonable prices from you then people can make geodesic tent domes but you need to make the 6 way connections and the 5 ways connections and also the 4 ways too .

1:37 Produces carbon that acts as a lubricant. Aluminum is a pain to work with. It likes to act more like a stick of butter sticking to everything. To keep it from sticking to the ram it gets a layer of carbon. When another billet needs to be added to the machine both billet faces get a fresh cut and placed together quickly before excessive oxidation occurs. Rinse and repeat.
1:38 This "fire" looks like hot plasma. They use it to remove oxides from aluminum surface. I am surprised that they use plasma on one end of the aluminum blocks and cutter on the other end. I would use plasma on both ends rather than wasting the aluminum. 3:01-3:06 Despite their effort to remove the oxide, the imperfect bond between the blocks is visible. I would solve this problem by cleaning entire surface of the aluminum blocks with the plasma. Furthermore, I would run the extrusion in argon gas rather than in ambient air to prevent the oxidation. Nobody does it at present because industrial engineers do not have common sense.

Flaming the end of the billet creates a layer of soot, so the hot aluminium won't stick to the large extrusion piston.

Yup. That is exactly the purpose. If you notice the end of the ram has some aluminum stuck to it. That is what they are trying to avoid.
Those are very versatile alu-profiles. Love those ones👍👍 If you want to build a 3D printer, that's the way to go.

Possibly to burn the ink off so it does not contaminate the processing.

I think they need to reheat the front surface a bit with the fire. The rest will get much hotter as it's compressed inside the extruder.
Wrong. The workpiece is heated completely up to 450-520 C. Moreover, the container where the blank for pressing is inserted is also heated.
That was the back end and it gets chopped off. It gets soot from the flame to stop sticking to the piston.
