The IDRA 8000-series of presses are going to be positively Brobdignanian and requiring of foundations even larger than those for a Thermarest mattress. Is what that video is showing sufficient for one such press? For two?
And why the 8000-series for Shanghai, if that site is for construction of Models 3, Y and 2? Possible answer: Although I think Shanghai never can make sense for Cybertruck, given the likely geographic demand for it, I do think that Tesla will be providing different varieties of its Semi around the world, and Shanghai makes terrific sense for such manufacturing.
On the topic of gigafactory foundations: "If you like that, you're gonna love this"
- from South of Phase 1 of GigaShanghai:
Namely a basically, enormous and very deep foundation which has been under construction for a very long time now. Is this for an even bigger Giga press or for something else (video title suggests stamping) ?
Yes, the video is of the foundations for a stamping press in Shanghai. This stamping press appears to be much bigger than the two stamping presses already installed.
This is not to be confused with the Giga presses which are High Pressure Die Cast presses. Those are located elsewhere in the Shanghai plant. The foundations for those aren't nearly as beefy, as is clear from the Berlin and Austin construction processes.
