I’m thinking that both Cyber Truck and Semi will be sharing the same giga -casted power skateboard. I’d like to hear how IDRA’s wait list is 3-6 years with Tesla permanently at the head of the line. Also, as IDRA can only make a handful of these each year, whenever Tesla announces a new production line, that means at least two 6k or one 9k ton press that further delays end of wait listed deliveries. No wonder “the competition” are like door mice on their adopting anything like this technology.

The machinery is just sitting there. Doing nothing. It probably isn't really a machine tool, more likely a bunch of parts waiting to be assembled.

The giga. Press is indeed a very innovative engineering feat in car manufacturing. It reminds me of a visit as an apprentice to the Cincinnati factory in the UK to view the engine transfer machining line that they were making for one of the British car manufacturers. That was about 1960. The idea was to revolution engine production from single operations to an automatic process. Minimised handling and people and reduce costs, and improve quality.

Here's the reality. Tesla had too many parts, on the back end. That's too many 'failure opportunities" in their design and it cost $2000 too much to make the car by its original design. So with recommendation from Sandy Munro, they converted those many parts into one part. BUT... Here's the con in this story. You see other car companies know how to make cars, they didn't need a giga press to make cars. The legacy car companies have decades of experience in making far more complex gasoline and hybrid vehicles by the millions, compared to a simple car with just a battery and motor. The giga press is a fix, not a feature, nor does it put Tesla ahead of any car company who already make up to 10 million cars a year. That is the con.

They're selling you a car, not loaning it to you, they dont have the obligation to buy it back for you at any price, so they will sell you a car at a market value, and, if it suits them recycing them, buy it back at scrapyards for scrap value.

Don't crash it, though. Aluminum is hard to pull back into shape, if the cast piece is even able to be pulled. Also, aluminum panels cannot be repaired in most body shops, requiring specialized training and equipment to repair correctly. This is why aluminum-bodied Ford F-150s have a higher salvage rate because of the costs to repair.

Regarding injection pressure vs clamping pressure, think of it like a hydraulic cylinder. To use simple math. If the cylinder full of molten metal (a fluid) has a area on a plane perpendicular to the direction of travel of 100 sq inches and the ram applies 100,000 pounds of injection force then the fluid would be at 1,000 psi. If the mold into which that fluid in injected has an area of 1,000 sq inches then a clamping load of 1 million pounds would be needed.

One thing that all these videos about the gigapress and model Y front and rear bodies always forget to mention is the fact that the part still needs to be machined. Such as this video at 5:50. After trimming it goes into a CNC machine so that several holes and slots can be machined into the part. The casting does not go directly into the assembly line after trimming.

Another thing they forget to mention is that those parts can't be repaired in the future. A crash that would be perfectly repairable on a traditional car will mean a totaled car with these huge single piece parts.

[@michaelisaacson9735]

Great video, thank you. But...heavy collision repair depends on body shops being able to cut out the bad parts and re-weld in new structural members. What happens with the front or rear of a Gigapress-formed Tesla? I'd have to assume that Tesla will specify that a subframe, once damaged, is irreparable and that any such repairs absolve them of responsibility for subsequent crash damage. The only option would be to replace the entire casting and that, unless it's to be done to a car less than three years old, might be too costly to justify if that repair would cost more than 75% of the vehicle's current value. Teslas have an excellent residual so maybe they get a break there, but surely five-year-old or so cars will need to be totaled.

That will make people look elsewhere for a more traditional build car or the car brand has to give some of it savings made by these new casting methods back to the costumer, which in case of tesla with a ridiculous margin of 30% is very doable. More so if they really want to make electric driving affordable for the masses instead of maximizing profits to pay for Musk's expensive hobby.

It's beneficial for the manufacturer, not the consumer. If that vehicle is in an accident, it's totaled.

Let's think about that. Minor collision, no difference. Force sufficient to damage a component that's a long way from the peripheral of the vehicle?

Would metal crumpled then pulled straight be fatigued, even if not visible? Would that vehicle be guaranteed as crash worthy as a new car? Front rear casting..... If the damage is deep enough, the same question applies. Will it be written off? Or, Is there a possibility that the whole "front clip" could be unbolted from the steel passenger cage, replaced by a new casting, then (modular!) components swapped over, or replaced? Would that be comparable in time to the bodywork required a conventional chassis? Would the car be straight? (almost certain perfect!) . Have Tesla, or crash repair experts thought about this?

Great job! I assume the presses for the truck will make similar castings and the exterior will be stamped. The entire structure will share the structural load instead of a subframe . There will be significant weight savings compared to the conventional frame and body design.

[@mattgraham4340]

If they make the exterior panels the way they pitched the concept, many of the exterior panels would be made with press brake processes using the custom SpaceX alloy of stainless steel (which is of a thickness and strength that is not suited to stamping). That was part of the reasoning behind all of the straight line corners. I'm not sure how much that will hold true in the actual production product.

And how would you repair a single cast frame after an accident, I mean you couldn't swap out part, you would basically need a new cast frame and transfer all the car parts.... It's ridiculous. But the whole Tesla Cyber truck idea was to build a spaceship like exoskelette without a car frame inside. That was the whole point. And I hope Tesla does it.

There is a tremendous amount of engineering that goes into this sort of thing. I wonder about cycle time. With a single Giga-Press, you get one sub-assembly per cycle of the press. So production is limited by this cycle time, which could be several minutes on an aluminum piece of this size. There are only 525,600 minutes in a year. Tesla wants to produce 1.4 million model Y in a year. That means the press would have to cycle every 22.5 seconds. This is 100% operating time, no downtime, no scrap. I don't see how they can do it.

[@deathjunior7755]

Honestly I'm more curious on the frame reparability from an engineering perspective. Seems like injection molded frames will also make them substantially more expensive to repair should the frame suffer damage. So what I'm curious about is the frame tougher because of this and is it tough enough that so few of them receive frame damage that it makes up for the repairability?

[@ml219]

My thoughts also, probably not that repairable. These giga presses, make chassis thinner/lighter/stronger with fewer pieces, but they dont seem to make enough parts to sell to third party repair shops and have to replace whole chassis. TSLA is on path of efficiency, which also means, constant small hardware and software revisions, which also means that the cars a little different from one made 6 months ago to now.

[@quademasters249]

If it's damaged enough the frame is damaged, likely the insurance company will just total the car. That's true of conventional body construction too. I'd rather my insurance company total a heavily damaged car than let some cobblers repair it and hand it back. There aren't that many body shops that can handle aluminum repairs in general.

@@quademasters249 depends on the car but frame repair is a thing.

Don't forget the 'hydraulic' effect a 200 ton injection force by a 'small' pisto generates a massive psi on the injected metal which is then translated to the much larger effective area of the cast part trying to force the die open with the same psi. Hence 200t in 8000t to hold it shut. The injection pressure and flow rates stay the same, so if you want cast larger pieces you not only need a larger frame but a much larger clamping force, double the linear size four times the clamping pressure at a guess..

Very interesting! A cast aluminium part has many advantages. In addition to what is mentioned in the video, there are some more points: its lighter than steel, it is more corrosion resiatant with less efforts in coating it, and it can produce very complex shapes in one production step. But I dont think it makes much sense to cast the entire car in one go. Simple components like panels on the outside are easier to press from thin sheet stainless steel. Casting aluminium that thin is probably too difficult, and steel is also stronger. But for the frame work its a real clever idea. All this goes, however, totally against the business model of the established car manufacturers. It would have been possible since decades ago to build cars that dont rust- but thats the exact opposite of what the manufactorers want. If the competition wouldn't prohibit it, they would build cars that desintegrate after 5 years, so people have to buy a new one. But obviously Elon Musk is not the kind of business man that you usually find in big corporations.

[@papapsych2746]

Aluminum is less ductile than steel and has less elasticity making it prone to cracking over time, this is why suspension components will never be made out of aluminum, and aircraft have to recertify every so many flight hours. I doubt they are stamping their steel components out of stainless steel but 300 series stainless steel, will rust with the combination of salt and water in many northern parts of the world. 316 stainless will not but I can guarantee they would not be using that. At the prices a Tesla costs you are just getting what you pay for

[@petebeatminister]

@@papapsych2746 Well, the stability of such aluminium casts depends on the design. It takes a lot of developement (and perhaps some fails) to find a real good design. And Tesla does make cast suspension components now for the Model Y, replacing some they made from stamped steel and plastic before. Acoording to what they say, the new Cyber Truck is made from stainless steel, and it has been done before already, like for the Delorian. And if it really doesn't work, there are always options like using carbon fibre parts. If it is done in automated production, its not even very expensive. I'm pretty sure if Tesla invests billions in new factories and machinery, they know what they are doing.

@@jimmykruspe Wrongo, Bub. The battery is only about $3,000. An average Tesla sells for $66,000. So the battery is only 7% of the price of the car. And in most countries it is illegal to sell as "new" a car with used parts. So it's not only illegal, it's uneconomical to throw away the chassis.

Daang! That gigapress should scale space building. It can build cities to space and can do fast.👍

Just an outstanding video. This is a must see, educational video about casting. I learned a lot from this video. I hope you could make a part 2, and go more into the science of the metallurgy, and the type of metals used on the Tesla cars. It's so fascinating, especially because they are doing a new type of casting that doesn't require any heat treating. Maybe you could talk about how they were able to make ductile castings that don't crack?

A metric 'tonne' is spelt this way, and Imperial 'ton' this way.. two different measurements and spellings

[@danielstapler4315]

In the USA yes, but the rest of the world just says 'ton'. Almost 50 years metric came to New Zealand and in the place I worked the old boys upstairs were big on the term "metric ton". But the term metric is redundant in the part of world that uses metric as is "tonne". The problem with your spelling rule is a lot people don't follow it, it's not a reliable rule.

As an electronics engineer I’m not interested in owning an electric vehicle in the least. I do find the Tesla story fascinating. God bless the Italians.

[@zonemk9406]

Thank you! Great video! Very informative and explaining well the casting process and how giga press is such a big thing! The efficiency of Tesla's manufacturing process just get's into a new level (again) and it's fascinating to see where it's heading next.

[@pryceallsop6219]

The idea of creating a Giga press is no doubt far different from the engineering of a Giga press, building the machines that build the machines is something of a dream, bringing a conceptual idea into reality takes some serious knowledge and expertise. Getting the machine right with so many technical components, such an expensive exercise. You have to be able to get it right or you will simply be financially ruined. Genius Piece of Equipment !

The real magic is in the fabrication of the mold itself. Imagine the massive milling machines carving negatives into huge chunks of steel.

Leave it to the Chinese or the Germans, nobody is building die casting molds in the states that big.

Casting steam locomotive frames and cylinders in one piece, 75 feet long and 100 tons in the 1950's was clever.

A 33% profit margin is gross. The Model Y went from $47K to $67K. WTF! I waited on the Model Y to get the V2 from Austin with diecast front and rear and 4680 batteries. Now it is priced out of my budget in spite of both diecast and 4680 reducing the manufacturing cost for Tesla. Customer rip off!

[@mik2137]

Sorry for you (really), but we cannot call it "rip off". 1) did the gross margin on a Model Y really substantially increase? What kind of improvements are included now? (double glass doors, improved suspensions, etc.) 2) as long as demand is so strong, they have to raise prices, Tesla is not a charity. However, they are happy to (and will) lower prices, once the market conditions are ready for it. 3) which components/materials got more expensive? For example in my company we have to use certain chips, which got 40'000% (!) more expensive over the last year and we cannot easily replace them...

[@richctv]

If you've been following this channel long enough, you know that the gigafactories are huge investments which were described as "Money Furnaces" - burning huge sums of money to operate. Be sure that these gigapresses were not gifted to Tesla at zero cost. All of this innovation and mechanization has to be amortized over the next decade(s) and the price of Telsa vehicles will reflect that. Tesla has to make of a profit in order to achieve greater innovation and and stave off the increasing competition.

[@MyUniversalUniversity]

The prices will come down when inflation turn around in the next few years. Tesla is padding to make sure they stay in business. It will happen. Elon said it today on Twitter!!

[@danielstapler4315]

Tesla doesn't have a significant profit stream from replacement parts which are fewer and they have said they don't see servicing as a profit center. ICE manufacturers can trim their margins because they make money after the initial sale, the Phillips razor blade economic model. A lack of downstream profits was the reason GM killed the EV1. Tesla needs a bigger margin on the sale. Also Tesla has only just gone net lifetime profitable and came close to bankruptcy several times.

[@Mcbleakbleak]

Great video! Thanks for the content. Just wanted to point out an error though :( At 7:03 the spec sheet is up for the max injection stroke and it says 1372mm and you say 1272mm. Im assuming the spec sheet is correct but just wanted you to know. Thx again for the informative video.

[@t_c5266]

one thought I cant shake is, if you've watched "wham bam teslacam" you already know that teslas get totaled notoriously easy. Being that this is a massive back or front section of your vehicle, one can only wonder what the future will look like, and insurance, when a fender bender will total your entire car extremely easily.

[@gfresh353]

At the 10 min 46 sec mark your quote of Tesla’s profit gain with the gigapress has a numerical error. I think you meant $5.4 billion, not million. Good summary of how the gigapress works.

[@Legominder]

Thanks for the video! I think a single piece doesn't make sense due to the crash repairability. Probably it's mostly either front or rear to replace - although I don't know how to handle this with casted pieces anyways.

[@mikewa2]

Won’t be capable of repairs

[@zefrum3]

Argon gas does not remove impurities in the casting process as Argon is inert. Argon atmosphere for liquid aluminum holding prevents oxidation and other slags from forming because Argon is inert.

[@TheSataraid]

This is one of the most amazing pieces of manufacturing equipment to exist… If ya know ya know…

[@YouWillBe322]

The thing is TEslas due to this process will worth a fortune in recycling industries. As it is more eco friendly while contains a more worthy material. Also easier to process so it will save on its costs.

[@ohgodwhat1]

Explains the repair cost. Essentially throw away a huge chunk of the car of either cast section is bent

[@themarsoff]

I don't understand why the castings on the press have to be placed horizontally? It's easier to use a vertical press, because the height of any part will not exceed two meters, and in most cases one meter.
