Inside Xiaomi’s near-fully automated factory that assembles a smartphone in 6 seconds
(e.vnexpress.net)
This is a most excellent place for technology news and articles.
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.
