nice job. different sizes of these bolts and nuts are used in almost all the devices. one of the biggest inventions of humankind

We used to have factories all over Melbourne making all this sort of stuff, with Australian made machinery. This is exactly the type of factory you could see in Dandenong, Moorabbin, Cheltenham, Braeside, and the list goes on and on across Melbourne, and indeed, across Australia. Then our politicians sold us out, with lowering and then eliminating tariffs that protected Australian jobs against the difference in labour and currency exchange. Now you get to watch the industries we used to work in on YT, and what was once our kids employment future, being done in China. Our factories are now warehouses for Chinese imports, and owned by Chinese. I love watching and indeed doing this type of work, however, it also breaks my heart to see it on YT now as a historical record for us. It wasn't only the factory workers that had work, it was the Receptionist, the BookKeeper, the Sales guy, the delivery driver, the cleaner, maintenance people, the local lunch shop that employed that extra Mum for the lunch rush, it was the flow on effect of making those nuts, that gave people purpose, employment, wealth and pride, knowing they were probably going into an Australian made ship, bridge, crane or even exported for our high quality standards. Manufacturing was the lifeblood and pride of our country, the little fish in a very big pond, we were big hitters for our size, till our politicians, as I said earlier, sold us out to foreign interests for their own personal gain. Australia had absolutely nothing to gain from it, only the politicians, corporations and banks had wins out of it. I worry for our kids future, as we've lost so much more than jobs. These were the factories where you could prove yourself, gain self respect and respect from others, learn new skills, be rewarded for your efforts, we developed lasting friendships, we met girlfriends, sometimes even wives, we had community in those workplaces. Now we grapple for part time/casual meaningless jobs, where we can be moved on at a moments notice, reliant on online dating apps to meet people, and buying online crap because you can't get it locally anymore, as it's all imported now. It's only one spoke in the wheel of this story though...

I am surprised by how much human labour is used instead of robots and automatic machines. A lot of it is repetitive and could easily be mechanized.

I see that water is poured over the white-hot pieces of round metal when they are forged into hexagonal parts. Why doesn't this produce a big cloud of steam?

Thank you for the video, but I already know the process of having big nuts. 😊

I love videos like this, but this one makes me wonder if creating the steel and then forming it into 1" or so rods and then cutting the rods and once again melting those cut pieces so as to make big hex nuts could not be made with only one melting. I also like how each nut is tested on a threaded rod, something I know is not done for the small size nuts and bolts I buy, some of which simply do not thread properly.

So from a steel mill (with a rolling mill) you can get bar stock, billets, rod (like this), sheet, plate and rebar. With those, you can make thousands of things. They just don’t make enough of these to put the factory near the steel mill to have hot rod ready, and it’s not efficient for this factory to make their own rods.

@@jakeharris9075 There's a lot more to this than meets the eye. The metallurgical properties are very important to making nuts and bolts that can meet the specifications for strength. There is a big difference between "melted steel" and steel formed when it is red hot. In a rod mill, they start with molten steel cast into billets. Typically these are square shapes formed anywhere from about 6 inch square to somewhat larger or smaller. But these are cast, and formed directly from molten steel. The billets then get reheated to red hot and are "rolled", meaning that they are stretched, elongated and compressed under shaping rollers using high pressures. The rolling process is key because it aligns the molecules within the steel, which greatly improves the overall strength. This is a continuous process and a 20 foot by 6" billet will be squeezed down to form the round bar you see in the video. As the billet gets squeezed down and shaped it becomes longer, so at the final stages, that round rod is flying through the machinery at high speed, while the billet may still be in its original shape and moving much more slowly. It's pretty amazing to watch this red hot "spaghetti" zooming along a long roller track. In some cases that rod may be coiled up, but in this size they are usually sawed off to length as they are moving down the line. Once in this rod shape, they are often heat treated to adjust the hardness and other properties. Also very critical is the exact formulation of the molten steel with different alloys. Very small fractional percentages of various metal alloys will make a huge difference in the metallurgical properties. (Steel is not a generic material) As the rods are cut into slugs, reheated and forged into the basic shape, the temperatures and amount of displacement in the forge, are all important variables that add up to the final metallurgical properties. As the threads are cut, a form of "cold forming" takes place, which also contributes to the final properties. The process itself is highly engineered to achieve the final desired properties that meet the specifications. Again, much more going on here than meets the eye. You can make nut that look just like this, but I wouldn't trust them on a big structure. You can find videos of Indian, Pakistani and other countries described as "How nuts are made", but they look nothing like the process you see here. Typically, they are some little "mom and pop" shop using chucks of rebar or junk steel. They heat it up in a very much uncontrolled fashion and then get handed to the next guy who stamps it in a big hammer forge. Then they cut the threads by hand. The trouble is that side by side, you probably can't see any difference. But one is a real, high specification nut and the other is a piece of shit!! 4 or 5 guys working in one of these little shops can probably make several hundred or more nuts in a day. But if you want to buy the high grade 2" nut produced in this video, you'll pay around $30 each. Those 4 or 5 guys combined don't even make $30 together for a long day's labor. And their processing costs are some gas to fire their small reheat furnace, some scrap steel and some 100 year old forge they bought at scrap prices. So I think you get the picture. The little shop probably makes a nut for 50 cents, maybe a dollar, but passing it off as the real thing has a huge profit margin. If you are doing some little shelving project using 1/4 -20, grade 2 bolts, you probably wouldn't know the difference. But imagine putting a bridge or building together with this cheap shit!!! And in big lots, there are millions of dollars to be made selling the low quality, counterfeit fasteners. It's a serious problem. Ironically, in their home countries, they use this cheap, sub-standard shit every day. We really shouldn't allow these third world countries to even participate in this market. But because of the money involved, somebody would find a way to cheat the system. With many large contracts today, the contractor may be assigned to supply the fasteners and some dumb ass bean counters who are supposed to watch it, may never catch it. Well engineered projects must have measures in place to ensure the quality of the materials meet the specifications. So, in answer to your question, you don't want to shortcut the processes involved without fully understanding the implications. That is essentially what these third world shops do. The Koreans, (South), have some excellent engineers and large industrial processes. Most of what they learned and the technologies they use, came from Japan. Koreans are very good at steelmaking and have good quality control. But they have some people in business who are no beyond looking for easy profits. Not so long ago, some Chinese steelmakers were shipping cheap Chinese steel to Korea to essentially be rebranded, as a way to get around tariffs on some steel products. I have little doubt that some very large steel consumers may have been involved in the ruse or at a minimum. looked the other way. Steel can be pretty forgiving and it's an inherently very strong material. But certain applications rely on the engineered material properties being what they are supposed to be. Years ago, many things were overbuilt to a large degree. That made sense when the materials used were not precisely made. But in modern times, designs take advantage of the very specific material science and the properties associated with them. The very high performing materials need to be made to exacting specifications. But by using these, the total amount of material can be much less. Lots of advantages to using less of very high performing materials. But the materials need to meet the specs or the design may be compromised. Critical structures are still over engineered, but to a much lesser degree than they once were. Modern engineering tries to build redundancy into designs and avoid single point failures. But assemble a bridge or building with substandard fasteners and you can create multiple failure points that may well go unnoticed.

I love watching Korean factory videos with very hard working people.

what would they do without these old oil barrels?

Я реально залип на процесс и досмотрел до конца

This is where Automation makes perfect sense. There is simply too much handling of each piece over and over again. Even just to put a little stamp on each nut makes no sense when it could have been stamped when the nut/hex was first formed. The steel shot cleaning wouldn't have adversely affected any stamp marks. There is just too much repetitive manual handling that could easily be eliminated with the proper machinery. It would still require humans to maintain the equipment so few would lose jobs in the long run but the automation would make these nuts much faster and more accurately. I say the latter after watching the Threading which was often on an angle (not perpendicular to the nut face).

Parts of the process yes and you can see a little bit of that here. But as someone who has spent a career in automation, the limiting factor tends to be a process step that takes the most time to accomplish. There are several of those time consuming steps here. Two very common ones that are limiting are heating and cooling. Time is an important factor in achieving the right metallurgical properties. There's a lot that goes into making the bar stock, so those processes are best treated as their own process and using pre-made bar stock as a raw material. Heating and cooling cycles lend themselves to batch processing rather than a serial step in a larger process. Another such step is the shot tumbling, which takes time to do. There could be some other ways to accomplish this, but it does tend to lend itself to efficient batch processing. In this particular instance, some gains could be achieved with automated handling. Not necessarily a time saver, but probably a labor reduction and an improvement in safety. Some of the steps here are their own process and wouldn't link up well in a serial fashion.

Super cool, I was guessing they were using induction heaters to get the material up to temp in a short amount of time and then seeing when they made the bolts pretty much confirmed that.
