If they sell 1000 units a week, standard 50 week year, thats 50000 units with an average sale price of $264 thats 13.2 million
Scale that down to match your 1.35m annual... thats 100ish units a week at 50 weeks
This is purely based on selling Billet Boxes only.
I don't think they can pump 1000 units a week... not that I know their process or capabilities, but even using 5 axis with a yield plate of 48x48 that would still take hours (4) to pump out 16 raw boxes... say they do 2 runs a day, thats 32...x3 days (need days to assemble,paint etc) so theyre at 96 units... which is about what I think they do
16 raw boxes on a 48x48 allows 6 inches per box to be milled, although the boxes are only 4 ish inches, tool pathing etc.
Morning Coffee thoughts... could be way off the mark on everything, probably am lol... didn't account for material costs, warehouse costs, wages... which easily can make things look worse...BUT!
If china can do a BB and sell it for 50-70% differential, then their profit margin can't be way off and they are doing well if 50 or 100 or the magical 1000 a week
