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.

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.

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.

An entire vehicle in one casting is unlikely, but you could use cast body sides and cast door frames and maybe a cast roof frame and firewall.

Also, I seriously doubt that the costumer will ever see a cent out of it, and why would it? 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.

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.

It is weak, but in applications where weight is not a consideration, like structural steel, it is cheaper to just increase the cross section to get the strength required. Where strength to weight, finish or uniformity is important, cold rolled is always used.

How can a previous damaged teslas be declared safe to drive after a smaller crash, that can degrade the structural integrity?

[@rogerstarkey5390]

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? A "conventional" vehicle would need many panels removed, replaced, patched, welded, straightened, then possibly pulled on a jig? Would that be absolutely straight? 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?

its absolutely terrible idea to cast a car in one piece. Why? There is no crumpling zones in such structures.

Will be fun to see, when they crash, how do repairs will be there. Also, in today's standards, every car has the same strength on front and back of the car, so passengers in both vehicles has the same chance to survive.

Reparability will be interesting. How would repair be handled with such large castings? In a fairly minor accident press component can be repair or replaced. If the one big casting is damaged is the car needing to be written off. Not saying this is a bad thing but seems like a large change. Makes the car like a mobile phone an unrepairable disposal item?

[@steamtorch]

Would seem so. The structural battery pack is a non-repairable item too.

[@grumpusmaximus9446]

If the damage was serious enough to damage the front or rear casting, why would you want to repair it?

[@FKS1994]

Any crash that would be destructive enough to damage the cast would likely be a totaled vehicle, anyways. The front/rear chassis being two pieces is a lot stronger than one in which you are welding/screwing hundreds of parts so the structure of the vehicle is stronger.

[@obijuan3004]

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 makes up to 10 million cars a year. This video is basically a cover up.

[@FKS1994]

@@obijuan3004 You're an absolute clown. Sandy Munro has been advocating for 1-2 pieces chassis from legacy automakers for some time. The problem? Legacy automakers were making huge profits with their SUV and truck sales so being legacy companies, innovation wasn't really on their mind as the industry was stagnant. Tesla broke the revolutionary barriers. Tesla is the only car company that has made innovation in cars exciting the past five years. The other companies that make 10 million per year have been around for decades and they are inefficient. Per sq ft of factory space, Tesla is the #1 in terms of production efficiency. You can't use the same factories to create EV's... so who cares about ICE factories if they are largely irrelevant and outdated in the future? Tesla's factories are all EV-purposed. Wow, amazing... Toyota can sell 10 million ICE vehicles. That will then be 9 million... 8 million... 7 million... and eventually fewer than 1 million ICE vehicles because no one is going to buy them in the future due to EV's. The Giga press advantages = stronger base, easier to manufacture, less labor, fewer robots, and much more efficient... that leads to cost savings. Other car manufacturers didn't do it because they didn't care about innovation. New year, same car but all they did was change the interior LED lights, LMAO.... Yeah, these other car makers are so advanced. That's why they let a guy who had zero experience in the auto business who sold PayPal become the #1 EV automaker in the world. So advanced!

I don't believe for one minute that IDRA came up with the idea for the giga press. Tesla queried them to see if they would do it, and then Tesla sent engineers to work with IDRA on the design and fabrication of the press. IDRA may be great at making presses, but they would not have known what Tesla requires in the design. Also, I understand that SpaceX was brought in to come up with a new aluminum formulation to work with the press.

@@mohammadwasilliterate8037 @Bill Weber is correct. There are A LOT of aluminum alloy press companies (Contech for example in the US) for automotive components, just not on the scale and size Tesla engineers proposed. Tesla, just like SpaceX, has the engineering discipline and understanding of evaluate, integrate, and eliminate - meaning Tesla is driven to evaluate the reduction (elimination of) of well of 200 individual components at the rear, and hundreds of manufacturing process steps. Tesla and IDRA together figured out the proper alloy, pressures, flows to cast the back 1/3 of the vehicle in one casting.

[@makerspace533]

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.

[@petebeatminister]

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.

[@paul5683]

Or on the other hand, getting it right in production. Just because you have a mold, doesn't mean that the parts will be correct when you make them. Die casting can be a lot harder to pull off than it sounds. Lots of potential for bad parts. Plus mold service is going to be on a new level with this one mold being about the size of a mini van. And die casting molds are notorious for needing work done on them.

[@kek207]

One disadvantage: If you damage the frame somewhere, it might have to be replaced completely. Basically you can throw the car away

Depends whether Tesla/insurers will approve repair sections/plates being welded in. Positional aluminium welding and non destructive testing of said welds is much more specialised than welding a standard steel unibody… So it’d be a pricy repair.

One down-side for using the single cast component for large parts of a car. A car accident... Anything that crushes, cracks or breaks the casting requires a new casting. If you priced that casting, it will probably almost the value of a car due to the cost of removing the damaged part and replacing it with a highly priced replacement casting. More than likely, anything that breaks the casting will end up as an insurance constructive loss, or total the car and replace it. Your insurance will cost more since it will cost them more to keep most of them on the road.
