We can see they work with such care, pride, and skills. It’s the reason why Korean products are quality. Big respect to Korean manufacturers and their products.

Steam curing of concrete at atmospheric pressure has the advantage of accelerating the hydration reactions of cement. Consequently, the material develops compressive strength and reduces its permeability in a shorter time compared with standard curing under ambient conditions.

The impact wrench used to tighten and loosen bolts is just a large version of what a mechanic would use to remove and tighten the lug nuts on a car wheel when changing a tire. It is basically a motor operating from compressed air instead of electricity. The "white air" coming out of the impact wrench tool is just air with some moisture in it from condensation, it probably also has a tiny bit of oil with it (very little), there is usually a very small amount of oil added to the compressed air to reduce friction of the moving parts inside the impact wrench. In other words what looks like steam coming out of the impact wrench is mostly vaporized moisture and air. It would not be hot or harmful. A large volume of air is compressed in the air-compressor and on a humid day moisture is in the air that gets compressed, when the air comes out of the air tool it can look like steam or gas. There are water separators that can remove water from the compressed air that can be used with tools such as air pressure operated paint sprayers and other types of equipment when the moisture would be problematic. I hope this is helpful = )

I've worked in plastic molding and precast concrete factories and I gotta say I loved it. Hard graft and a sense that I did a good job today. Especially the concrete shop. Thanks for the wibble wobble, wobble wobble flash back...

impressionante a produção PARABÉNS 🇧🇷👏

They are the men and women that keeps the world running. There in all the nations of the world. If it wasn't for people like that the world would starve. Unsung heros of the work force, bless them all

The white color of the cured concrete is due to the type of cement that is used. Some cement is much darker gray when cured. Portland cement is commonly used though the quarry where it's mined will have different shades. It is obviously a high strength cement to remain strong with the amount of water used which looked to be a high slump mix. Generally a high slump results in weaker concrete, a higher ratio of cement to the aggregate and sand will offset the high slump. Slump is the speed which the mixed concrete flows, low slump produces a stronger compressive strength. The engineers test the strength for the task needed. The structural columns had a relatively low slump, which gave them a stronger concrete, the water ditch/canal forms obviously didn't need that degree of strength, they are essentially a supported trough.

amazing how some tasks are still manual, especially the cake baking bowls lifting on / off the conveyor and the final boxing and parcel taping. Yet they clearly have invested in some pretty good robots for most of the line. All that twisting and turning those people do, goodness knows how they are not crippled by repetitive strain injury.

Clever idea, I love the finish. Beautiful work 👏

I guess we generally do not appreciate enough all those hard workers producing for us consumers ...let's be grateful and say Thank You.

건설현장 자재과에 있으면서 많이 본 파일인데 속이 빈 부분을 형틀로 만드는줄 알았는데 원심력을 이용하는거였군요. 좋은 영상 감사합니다 ^^

Fascinating and a bit nervous at watching how close and attentive they must be not loose fingers or have catastrophic accident in the making if they lose concentration ...disaster could happen.. very industrious people these Koreans. Enjoy the mechanical interactions while in the making of the products. Great clips..

we are amazed at the Machines used to make these concrete columns . Our world in Korea is wonderful. Thank you for taking the time and amazing us. OORAH!!

Very nice process. In the round piles it looks like they prestress the concrete using cables not re-bar, which is dead steel. The cables are also strengthened with welded radial steel. This produces the best of both materials. Good video.

so many moving parts working in unison is amazing. The designers of these great machines are truly geniuses. 👍

언제 봐도 신기하고 대단한 생산공정.. 진정 세계를 만들어가는 이는 엔지니어와 그 종사들 아닌가~~!!! 멋지다~!!

Как все удивительно и позновательно, кто то ж придумал такое мощное производство . такие огромные станки , такая мощь. Очень интересно .

15:05 White air is just moisture in the air when it was compressed by the large air compressor they have. When air is released by the tool after doing its work going from high pressure to low pressure the water condenses into droplets and that is what you are seeing. When concrete dries it changes color same as wet wood changes when it dries out.

@ 2:23 the worker adds a "mandrel" to both sides of the steel frame. This mandrel stabilizes the steel frame so it can mount in the mold. The bolts tighten the mandrel. The mandrel stretches the steel frame a bit to remove any sag in the frame.

You know a lot about the whole process and operating. What a fantastic hard working team. Starting from the beginning. Who ever invented the machinery and technology should be highly commended for the ingenuity. Thank you for sharing this very informative video, my hat to you all. AMAZING. Jose from Melbourne Australia.

Admirable the people from South Korea, Heavy workers, inteligent and respectful. So sad how the north became so manipulated and exist in a parallel reality. Thanks for sharing

I love Korea its workmanship its craftsmanship and the lovely Kia cars you build

This is the type of thing that I never get tired of watching. It is so informative

23:20 Silk screen printing. Have to admire the accuracy of this guy's work.

콘크리트 말뚝이 이케 만들어지네요 ㅎ 보기 힘든것만 찾아서 보여주시는 팩토리몬님 감사합니다 !!

Unbelievable what becomes of the sum total of experience, ingenuity and steady work.

I enjoy seeing how things are made..thanks for sharing.

The engineering and co-operation between the different acumen to accomplish such feats is truly inspiring.

You can see the same condensation of moisture due to pressure changes coming off the rear of Formula One cars under certain conditions. Compressors have systems to try and drain most water from the air that they compress because water and machinery do not play well together. Water does not compress and it can compromise lubrication. Nice video, very informative.

Supermaravilloso y, de.gran inteligencia y técnica . Gracias.

Fascinating but dangerous work! Well done on this manufacturing process guys, amazing work and most interesting to see the whole process, brilliant and thanks for this.

I'm fascinated with the engineers that designed all that machinery to make that stuff

Excellent video! Great editing showing processes in the logical order from start to finish, no narration required! Very enjoyable and I hope to see many more full length videos from you soon!

The people doing the video are good at what they do. Keep me riveted to my seat lol. Keep me wanting more

You did an amazing job capturing an unbelievable process .

The longer the concrete cures after the Setting, the stronger it’ll get. It usually takes 30 days for the average concrete to reach adequate psi. It takes usually up to a year for it to reach maximum psi. much depends upon the formula. Today they are adding more more formulas for different concrete and its requirements. There was a time it was so much more simple some 50 years ago.

one of the Most Satisfying videos i've watched in a long long time that was awesome.

Nice production on how to process from raw materials to finish product amazing

I spent part of 1979 and most of 1980 in the ROK and those are some of the hardest working people I ever saw. Some things they did seemed to be the hard way to do it but by thunder those folks do work hard!

Although I've seen the pilings one before it's cool to see all of these processes together. Great video!

really nice video! I like your documenting style, no bullshit, no pointless emotional narration. jus the target itself, very nice, great job!

The air releases from an air powered tool just like the exhaust from a car. It compresses the cylinder and releases when the cylinder retracts, then compresses again with more air pressure.

I have seen a Korean Pre-casting concrete plant in Iraq! You are excellent! Koreans were number one!

I have done many repairs to similar molds. The running rings and rollers would wear out from such heavy use. I would load the molds into a very large lathe and true up the running rings. The lathe was about 60 feet or 18 meters. The molds I repaired were for concrete poles, like street lights, not pipes. Interesting to see how the final process is accomplished.

LOVE the real world application of the hard hat example, of them hitting it with that hammer, keep it up buddy! Keep asking them questions!

Yes, les matelas de l'Italie Coréennes !! Bien connu et reconnaissable grace à leurs drapeau à l'envers, en commençant par le rouge plutôt que par le vert ! Bravissimo !

La trayectoria recorrida atravez de los años de estas industrias son muy interesantes e impresionantes, felicidades por esa cultura forjada con el esfuerzo, trabajo, y sudor de todas sus generaciones, felicidades a toda es cultura trabajadora

15:06 "White Air" is water vapor from the air supplied tools air supply. Without regular draining of the water from the air holding tank, you will see "white air" (water vapor) escape from the tool when it is used.

Очень познавательно. Люблю такие видео. Спасибо. )

White 'air' from the pneumatic wrenches is because of the water vapor in the air, when it gets compressed some water forms in the tank and will go down the lines, so there is a light vapor spray that will come out. Also, some pneumatic systems will add oil to the air stream that will self-lubricate the machines from the inside while they work, that can also cause a vapor.

Интересное производство. Приятно смотреть! СУПЕР!

Все технологии понравились! Класс!!!... Всем мира и добра!

I like your sense of humour with your comments and subtitles awesome job well done mate and greetings from Australia

플륨관 제작은 대충보았는데 싸이즈별로 제작하는게 참 흥미롭습니다. 최대 1000관까지 설치해봤는데.

The "white air" coming out of the air gun is the condensation of invisible water vapor naturally present in the atmosphere that was "compressed" by the air compressor and when released coming out the air gun, expands adiabatically (look it up - cooling by expansion) to form very fine water droplets that are a form of cold steam, a process similar the creation of clouds when moist air rises and "cools" by expansion at higher altitudes.

25:37 -- Casaflex Mattress factory in Korea that says "Made In ITALY". Hmmm.

Que bonito trabajar con toda esa maquinaria,es tecnología avanzada,felicitaciones

Increíble el trabajo de las máquinas. 👏💯👍🏻

40:26 that’s a big job for that puppy, guarding all those clay pots.

What are these concrete columns used for? Very interesting video, pity it was edited so I couldn't see more of some of the processes, but very educational all the same. Thank you.

The designers of these great machines are truly geniuses. 😲😲

These guys earn their living. This is how successful countries make their way.

Excellent videos! Well filmed with great focused detail including close ups of operations and even slow-motion shots. The various manufacturing processes are sequential and easily understood. The explanation captions are well written. I have reviewed over 75 manufacturing processes (Quality Control Engineer) all over the world including S. Korea. Well done! I will subscribe. I am anxious to see more.

I noticed the hooks that they use to pull the concrete out of the mold are attached to the reinforcing steel, this is not allowed here in California as it is like a fuse of rust, it continues into the core steel where it can expand causing the concrete to fail.

Now that is a wonderful manufacturing process for concrete pipes.

The *things* we fail to appreciate in the modern world! Thanks again!👍

The guy who does the captions for this is awesome! Subscribing because of that! Love the personality in them and not being a robot!

Incredible .I would love to visit the Factory.

When the men are using the air tool to tighten the bolts at the 11:00 minute mark , the wet coming out of the tool is water . When air is compressed the moisture in the air is compressed also . The moisture has to go somewhere and it travels out of the vent with the excess air . Great video !

The “white” air is moisture from the compressed air driving the tool. After extended use the tool will cool to point of chilling the exhaust air. So you have cold air hitting hot air and make a small cloud.

I think the "white air" you see from the gun is just moisture from the compressor. Compressors need to have the storage tanks bleed of moisture periodically to keep the air storage tanks from rusting. It could also be oil mist as air guns need to be lubricated along with the air.

"White air" is from moisture in the compressed air rapidly cooling and turning into small ice particles as the air rapidly escapes from being pressurized in the tool to "zero" pressure in the atmosphere. If a tool is run for long enough, it will form ice on the outlet of the tool. I presume the concrete is whitened by the lime added to the mix for curing.

My compliments on your editing technique of showing the more mysterious processes twice.

日本の高度成長時代のプレキャストコンクリートは同じ用にして作られて、現場に出荷されたのである。 円筒形コンクリートは電柱や基礎杭に用いられているし、角形の部材は側溝に使われる。 その他にピアノ線を用いて作られる橋桁が工場で作られて、現場で組み立てるプレストレスコンクリートのは重田も製造されているので、日本では珍しくない。 製造する機械やクレーンはおそらく日本から輸出されたと思う。

The air that powers the rattle gun is compressed, once it goes through the machine it loses pressure which means it has greater volume, it has the same amount of heat energy in a greater volume of air, so the air is quite a deal cooler, that means that any moisture in the air turns to Fogg. Air tools especially when they are used a lot get really cold and you have to wear gloves, as they can actually freeze up, they work exactly like the freezer in your refrigerator.

A well made educational video showing some everyday items made by dedicated workers with the aid of intricate machinery so the rest of us can go to shops and buy such things, things we near take for granted, yet without dedicated workers across the world using their skills and resource to make all manner of things, the rest of us would be hard pressed to make any of it on our own.🙄 So a big thank-you to everyone on this planet who's efforts make it possible to posess and use such things, - barely stopping to think about the skilled workers and technology that in today's world have made it possible.😅❤💕!!!

The "White Air" is moisture in the compressed air line. No moisture separator was installed on the air compressor it would seem

Varmaa jännää ja uskomattoman hienoo tekniikkaa sellaselle joka ei oo maitokauppaa pitemmällä käynyt.

вот это процессы, очень круто делают мужики

Interessant de voir ces procédés industriels, qui se passerait du commentaire, et de voir comment certains pays totalement sous développés il y a quelques dizaines d'années sont devenus des pays hautement industrialisés, alors que d'autres s'enfoncent régulièrement...

the steam raises the temperature, probably speeds up cure time. If the concrete is exposed to the steam inside its mold, it may also prevent cracking while curing... but I don't think they're doing that. Probably the spinning negates that issue.

Ритм и скорость работы механизмов завораживают. Но мы не поддаемся эмоциям, поскольку наши рабочие при помощи молотка, зубила и какой-то матери могут делать то же самое всего лишь в два- три раза дороже, раз в 10 дольше и с 50- процентным выходом брака🐸

*very interesting* 🔥🔥🔥

saya pernah bekerja di kilang ini suatu ketika dulu. video ini mengamit memori. CEPCO Concrete Pasir Gudang, Johor, Malaysia

All the workers are admirable. The scale of the job is hard to believe even when you see things come together. I just think worker safety is lacking in a lot of the facilities. The concrete factories need more protective wear. A lot of people bending over when there should be chairs/tables/production spaces that don't make hours of physical labour even more excruciating than necessary...the facilities look like they make millions, it wouldn't cost much to improve worker safety. Great video! Thank you for sharing

Very good Job congratulations!! Brasil

En cuanto a la cámara de Vapor: En lo que el cemento se mezcla con el agua empieza una reacción conocida como fraguado del concreto, esta reacción produce un aumento en la temperatura del concreto y una pequeña disminución de sus dimensiones conocida como retracción, la retracción en elementos muy largos (mas de 5-6 mt ) llega a producir grietas que reducen significativamente la resistencia del elemento. El uso de vapor o "curado con vapor" suaviza las variaciones de temperatura eliminando las grietas por retracción, que en un elemento tan esbelto como esta columna (Debe tener unos 12 MT de largo) aparecerían con toda seguridad. Adicionalmente a eso el curado con vapor aumenta la resistencia del concreto.

The steam cures the concrete. This is one method of making reinforced concrete pipe used in storm sewers.. I have seen it as large as 72 inches in inside diameter. It is probably available larger.

Thank you for not having music playing i like the sounds of everything

Good Job, please make more like this 🇰🇷🇰🇷👍🏼🇰🇷👍🏼🇰🇷👍🏼

영상잘봤읍니다.수고와감사합니다 현장에서일하시는.모든분들안전과건강하시길

Vemos la maravilla que hacen las máquinas. Pero.....y, las máquinas ???? Quien las hizo. Cómo las construyeron ???? Mil gracias.

Работа простая, но потрясное зрелитще!

The second biggest steel mill - by the size - is in South Korea, at Pohang, called POSCO. Amazing magnitude. The biggest steel mill in the world? is also in South Korea (Gwangyang Steelworks). Of course there are a lot of great still companies by revenue or capital size.

Mi admiración a las tecnologías ,Japonesa ,coreana,inglesa ,alemana y de USA.lo mejor de lo mejor.

Parabéns, maravilhoso!!!Abs

It’s crazy how us humans can make just about anything.

Having the nuts attached to springs so the nuts don't fall off when loosened is genius.
