Xiaomi said assembling a smartphone from circuit board to finished product takes about six seconds, and, at full capacity, the factory could produce more than 10 million devices annually
There are ~30 million seconds in a year. So this factory is only producing 2 phones at a time? Assuming the article is accurate, I’m very curious to hear why this was chosen as a design
Especially since it says 11 production lines…
11 lines = 57.8 million
57.8/~10 means their lines are down 38.5% of the time?!?!?
Edit: Maybe the nearly 40% downtime is retooling for different models?
The rule of thumb is to plan for machines having 80% uptime. Mind you, new lines, and especially new technologies are often a clusterfuck until they mature and you really understand the quirks of trying to do what you’re trying to do with them. But yeah 20% retooling would make sense if they have a lot of models and a really complicated retooling process, but if that’s the case, well listen, I believe it, but I’d be asking questions about how to cut the tool change time down.
I’m assuming there must be downtime for maintenance and quality checks.
Woah
What Elon wished he could achieve
He is the single human with the most manufacturing knowledge in the world, after all.
