Thanks for this video, as always, well done the Engineers who design and construct these machines, it is a harsh environment and the robots do well to cope. It is staggering to realise that a modern car production line will need thousands of these wheels every day, with "just in time " production imagine the panic when a machine breaks down.
The process at 2:50 is a degassing process. Nitrogen is passed through a carbon tube which is inserted into the molten Aluminium. The tube spins and the nitrogen is flushed through the Aluminium from the bottom of the crucible to the top. The nitrogen has an affinity to moisture and effectively pulls the moisture from the melt. This process reduces or stops you having porosity ( tiny holes ) in the alloy casting.
Thank you for posting this. This video is fascinating and mystifying at the same time. Do you know what is happening during the times - two, as I recall - when the wheel is shown with a copper colored wire mesh item in the wheel center? The item appears to be roughly cone shaped.
@@thardyryll If you turn the subtitles on, it does give a brief explanation of each stage. The copper cone is labelled "foreign matter filter" - presumably to catch any last-minute slag making it into the mould.
@@StrsAmbrg I think they're just blowing the mould with compressed air to remove any dust or debris. The yellowish grey colour is just its natural colour.
@@thardyryll It’s a Silicon Carbide filter. They stop rubbish and dross entering the casting. Silicon Carbide wont interfere with the drilling bits like the ceramic filters which are quite hard. The carbide filters also tend to float to the top of the melt when reused although they are most likely using new Aluminium Ingots each time when making car rims
From the melting of pieces of aluminum ingots in the furnace, through dozens of processes to the final exquisite wheels, few people participated in it, and most of the work was handed over to the robot, which is very good!
wow! great contribution to Korean GDP and national employment. This implies that koreans love their country, working hard but doing out of love, with passion and excellence that is why their economy is continually blooming and its government also doing its best for the peoples' welfare. This is my dream also with the Filipinos , you Filipinos are intelligent and wonderful people hoping very soon that you can have hybrid elections without smartmagic so you can have good leaders to lead your beautiful country. True leaders should apply for govt positions not the incompetent and corrupt ones. Always remember that your inner virtues, talents, skills and elevated values are the true leaders. You can start your abundant consciousness programming thru your educational system by honing first the character of your students and the rest will follow. My good wishes to you, United Philippine Islands!
Fascinating - I'm always intrigued by production lines - one thing I thought was odd was having multiple wheel designs all coming out and along the same line for finishing etc - I'm sure there's more to it - also I never knew that the casting was formed further to get the bead on the inner side of the wheel!
These videos are great - but what would make them even better would be some description of what's happening - some description of the processes. Experiment with text subtitles and voice and see what's best. Like for example, at 2:38 - what's the powder being added to the molten metal?

As someone watching from the US • Watching your videos is most relaxing even at 2 x speed. Hope your customers appreciates this very important job • It’s good to see how well these workers are able to the job done in a quality way • Good to see that everyone stays safe and think about using safety equipment (gloves / goggles , etc) • Thanks so very much for posting and sharing! All the best and God Bless. 🙏❤🇺🇸
I've just watched a video of the manufacture of alloy wheels in a bask street factory in Pakistan using scrap aluminium with quality control none existent. The comparison is unbelievable.
Seria bom se tivesse uma legenda explicando do q se trata cada etapa do processo para melhor compreensão. É bom mas é mixa. It would be nice if there was a caption explaining what each step of the process is about for a better understanding of what is going on. It's good but its not
I am an old hot-roder, low-rider and car loving guy. I've purchased many cusstom wheels. The Amerian Raciing Vector wheel came out about 1972 and sort of started the custom aluminum wheel fad. Years later, when American Racing came out with the three-dimensional cast aluminum wheels, their man who designed the wheels quit and went to another wheel manufacturer. The problem for American Racing was that no one else knew the wheel design software. I just installed my fourth set of Keystone Klassic wheels on my newly acquired 1973 Chevy Caprice classic convertible (triple white with whitewall tires). The first "mag wheels" were really steel (except for Porsche etc). Now aluminum wheels are standard on many vehicles.
Думается, что самое удивительное во всем этом, не само производство колеса, а создание самого оборудования и установок, для технологического процесса!😊
Заготовки Rusal. Получается олигархи продали народный алюминий корейцам, деньги в офшоры и западные банки. А корейцы сделают с него диски и продадут это алюминий в тридорога назад обычным людям. Потом удивляемся почему так живем - без работы, денег и здоровой конкурентной экономики...
if you want to improve your car performance by changing the wheels/tires, the first thing, the very first thing you must check is, do the wheels weigh less than your standard wheels. If they weigh more than your standard wheels you are only going to be hurting performance. Weight added to area of the wheels- brakes- spindles- Control arms, shock absorber, that is called unsprung weight. That’s what your suspension has to contend with while keeping your wheels in contact with the road over irregularities like potholes, bumps, ripples.. if the wheels you buy or heavier than your stock wheels, your performance is going backwards. unsprung weight is so critical that for decades, Porsche has been using light wheels with titanium Lugnuts just to save a few ounces.. The Formula One world champion car builder Graham Chapman was once asked what does he do to make his cars so good in handling and cornering. He said that he adds lightness to his cars.. So if you’re buying heavier wheels than stock, using heavier Lugnuts than stock, and using heavier tires than stock, you are not improving performance, you are all throwing money away, and you are hurting performance.. when the wheel/tire combination weighs more than the standard wheel/tire combination, you will notice that your wheels/tires, hit potholes much harder, your suspension can’t recover as quickly as it used to getting ready for the next bump.. that extra weight being put into motion by the bump, the spring has to absorb that energy, and your shock absorber controls the spring rebound. That process takes longer the heavier the wheel is.. there’s one other thing to consider when you’re thinking about buying aftermarket wheels.. those wheels are not nearly as durable as stock wheels 99% of the time..They dent very easily.. just look at a Bugatti Veyron set of wheels/tires. To have a new set of tires installed. The owner of the Veyron hast to send the wheels back to Italy. And the price of a new set of tires not including wheels was $40,000.. formula One wheels for the Formula One cars, are not used a second time. They are so barely engineered that they cannot survive the stress of having tires installed, removed, and installed a second time. They’re only good once..
I thought Bugatti was based in France.What you have written here make sense for formula one cars not your average car.I do agree with you based on physics but when there are other factors effecting all said it becomes irrelevant a few ounces here and there.The main variant is load factor of number of passengers and other loads,luggage carried which has more influence on how the car behaves under those conditions.On the other hand we all know every bit of extra weight carried will use more fuel and effect suspension and brake performance but won't be noticeable as such as in your comment.
@@mehmettemel8725 you were right, the Bugatti is made in France as are the Michelin tires that come from the factory on that car. I remember watching one of the television car auctions is where I heard that a set of tires cost $40,000 and you must send the wheels back to the factory to have them installed. The announcer that said that on the television auction said Italy was where the wheels had to be sent. But I think you are right, it’s probably France.. I don’t usually remember little trivial things like that, but I thought it was remarkable that you actually have to send the wheels back to the factory to have new tires installed. I wonder how long that takes. At least a week.. The main factor is not how much of a load you were carrying. Absolutely not. The main factor is unsprung weight. Not sprung weight. unsprung weight is the weight of your wheel/tire/Lugnuts/spindle/control arms, all of those things that your suspension has to deal with in trying to keep your tires in contact with the road..That’s why I Porsche for example uses titanium lug nuts to save just a few ounces per wheel.. formula one is the extreme example, but the same principles apply and always will.. example I changed tires on my motorcycle/street bike. A Goldwing The used worn tires I removed, the rear tire weighed 25 pounds. Just the tire. And it was worn down I installed the same brand of tire but a different model made specifically for the goldwing’s weight .. The tire I installed weighed 6 pounds less before mounting on the wheel The improvement in suspension compliance and ride made it feel like a completely different motorcycle. It felt like it weighed 100 pounds less. When I would hit ripples. The suspension was able to recover quickly because it did not have to contend with that extra 6 pounds of weight.. The impacts with bumps was not as severe when your wheel strikes a bump. That energy goes into the shock spring.. depending on how heavy the wheel and all the components that are controlled by the spring are, that determines how fast the wheel can recover and return to the end of the spring stroke and be ready for the next impact, keeping the wheel in contact with the road surface. That’s the bottom line, how quickly can suspension recover. The energy goes into the spring, and the shock controls the spring.. I road raced motorcycles decades ago. i won 6 road racing championships, two time national champion.. I had a machine that had a single disc in the front. I thought I wanted more powerful brakes, so I added a second disc, caliper, mounting hardware, brake pads, related hoses, to my race machine.. I usually won at this track that weekend i showed up with double discs.. I went out in practice. I could see and feel that the machine was not accelerating as usual.. other riders on the same machine I competed against in the past were pulling away about 5 miles an hour which is a brisk walking pace.. in the corners, some of which had ripples, my suspension could not handle the second and third ripple while leaned over. My suspension started to chatter and I would go off-line because the suspension could not complete the compression recover cycle as quickly because of the increased unsprung weight of the disk and all the associated hardware.. I did not need 450 hp front brakes on a 260 pound machine with 59 hp.. even with a single desk I could easily walk the front wheel with a single finger.. duel disks have one advantage. They pull evenly on both fork legs and make the machine break in a straight line. But there is also a downside to the pull.. when leaned over and breaking, it pulls the wheels straight and makes the bike stand up in corners.. It was too late to remove the disc/pads/hardware/caliper that day, my heat race was was soon.. I did the heat race with the double discs.. rather than winning as usual comment I came in seventh. I was losing five seconds a lap.. at 82 mph average, that’s around 100 ft./s. That’s 500 feet per lamp behind the leader I was losing, seven laps, I want to over 3500 feet with that added unsprung weight, added flywheel which had to be accelerated, Gyro but did not like to change directions in S turns quickly,, and additional disc brake pad drag which is always present.. after that race, I removed the second disk and all the associated hardware which was around 7 pounds. On Sunday I started on the third row, and I won as usual because I eliminated that anchor Inn that extra weight my suspension could not deal with very well, and that gyroscope that did not like to Change directions quickly, and that extra flywheel that had to be accelerated.. I went on to win that race, and the championship that year. I learned about the importance of reducing unsprung weight .. years later, my two sons had an Acura RSX, and a Honda prelude.. they did all those things that young guys do to their cars, low profile wide wheels, and sound systems you could hear a block away.. I told them those wheels are going to hurt the ride, and the wider the tire, the worse the the tire is in the rain.. of course they didn’t listen, and they bought wide wheels and tires. The wheels were wide, the tires were wide and very low profile.. both of their cars road like Fred Flintstones car , Fred Flintstone had stones for tires.. it was incredible how hard those cars both hit even little bumps.. within a few months. All four of the wheels on both cars had dents in them because of the low profile tires that do not protect the rims as well as higher sidewalk tires.. aftermarket wheels do not have to meet the standards that the OEM tires have to meet. They are generally very poorly designed and overweight and made of Low quality alloys. They’re made to a price, not to a standard.. before we put the wheels on the cars. We balanced them. I have my own tire machine and balancer machine.. we had to stick an unusual amount of weights on a couple of those wheels/tires. there is an additional consideration to be made when installing wheels/tires. And usually they are high-speed rated tires. Here in Pennsylvania, USA, it is actually illegal to repair a flat tire on a tire with a high speed rating with a plug. No reputable tire store or garage will do it. So if you get a small hole in your very high speed rated tire, even though you are probably never going to go over 80 miles an hour on public streets. You have to buy a new tire if you have a speed rating of S or V or higher..No I Donely can you not repair a tire with a high speed rating, but those tires generally have a stiffer carcass, and, to have that high of a speed rating, they generally have about half the tread depth because centrifugal force causes a tire with more tread depth to distort and overheat. So, the higher the speed rating, the less tire you get for your dollar.. of course you have to do that if you are competing on the racetrack, but on public streets, you were just throwing money away to buy high speed rated tires.. to top it off, the higher the speed rating, the more expensive the tire is.. aftermarket wheels do not have the protective coating/finish that factory issue tires usually have.. they absolutely are not very salt resistant in climates that have snow in the winter where they salt the roads.. after about two years of problems with aftermarket wheels and tires that don’t last very long and ride like a rock. Both of my sons admitted that it was a mistake to put aftermarket wheels and tires on their cars.. they finally got it, and that is, the factory knows more than you do for every day driving on public roads..
What the hell, vidro jumps to a completely different wheel near the end of it. First one looked like a stock rim for a car manufacturer then it went "custom: on us!😆
Soon there will be not only aluminum. This one, I see, was produced in Russia, but the sanctions now will not allow it to be freely sold. There are many more metals.
@@redRusEmperor That's why the top of the Washington Monument is aluminum -- from when it was expensive to produce because electrolysis was not then known.
