I wonder if they are delaying the delivery event so they can crush the qty. The castings are surely the limiting factor of production numbers. If they delay and stockpile as many of those as possible and lets say they deliver in November. They could appear to produce 50k in 2 months and blow everyones minds. The factory is sized for it and who knows whats going on behind those doors. They could be fine tuning the highest production assembly line known to man in one of the largest buildings on the planet.
Actually, the castings are not the limiting factor. They can make a casting in 30 seconds. That run rate can more than keep up with the initial production numbers.

Where did you get that 30 second number? Idra said 1:30 to 2 min. Which realistically puts them at about 250,000 per year, 22k per month, with the two 9k ton presses going almost non stop.

This is exciting to see, it seems like the bottleneck here isn't the casting then. If the current ones we see are built by hand, it'll be interesting to see the production quality candidates that are built by machines.

I think a 90 second cycle was the number given for the smaller Model Y castings. I would not expect these larger castings to take less time.

(Dates approx) Some months back, steel deliveries were made to the 4680 zone. Roughly a month ago, a concrete pump was seen in action.

Just a few days ago, more steel beams were observed stacked outside.

It appears that they might be making alterations to the building to accommodate new 4680 lines.
They seem to want to produce at least some new 4680's ASAP, by expediting the process by partially constructing and installing 4680 lines concurrently.

The construction time, and 4680 production, if it follows what we have seen so far, may just align with scaling Cybertrucks.

This was quoted by Munro.

Your math is wrong. Remember there are two castings per truck, front and rear clips. So 2 min per casting would be 4 min per truck. Which equates to 15 trucks per hour, 120 trucks per 8 hour shift. 360 for every 3 shifts, 1,800 per week, 90,000 trucks for a 50 week year. So, they are definitely running much faster cycle times.
It may be a total to 2 min between injection molding, unloading and cooling. But while unloading a cooling they’re injection molding the next one. Thats what Munro was saying.

Musk said 500,000 if the demand was there..

I do not think Tesla would be so complacent to decide at the last minute that they need to scale to 500,000.

I reckon there would be use for more 9tons for other projects anyway, and they would have it on hand and installed ready to reach 500,000 in the normal course of CT scaling.

The other options is to say ... Golly Jee Mr. Musk... we think we should order another one,.. where do you think we can put it ?


No.. its ready now, and getting installed on time.

Unless I'm mistaken, two of the large presses were delivered so far. And the 90 second cycle time for the Model Y presses were between parts, so a new one coming off the press every 90 seconds.

Very exciting post. Got two questions.

1 - what is Tesla’s past practice on going to production. Do they make a bunch for employee testing and then slow down until they get enough data. Or increasing production linearly from start?

2 - If during testing one of the casts does crack in an unpredicted fashion, how big of the deal is it to modify the mold? Was the mold made in Italy? Does it have to go back there? Or it can be done in U.S. in a relatively short time?

I believe he molds are made here in the US, but they are costly in both schedule and money to produce and change. Hence why he "unicast" that would do a single casting for one vehicle end to end is such a huge deal, as part of the process is going to require a paradigm shift in how molds are designed and constructed, at least for ptototyping.
