Doing some quick numbers...let me know if this makes sense.
Let's just say $20M is break even (may be $12-15M but let's just see..).
I'm excluding salaries here since this may be negligible in my quick math.
1. $20M @ $11.40/shot = 1,754,386 shots (now this assumes no markup, which we will need to figure this in to make more sense below).
2. There are 1140 mins/day and at 3 mins to produce a part (roughly) that means 1 machine can produce 380 parts per day.
3. 1,754,386 shots / 380 shots/day = 4,617 days/154 months/12.8 years
Now...increase the number of machines assuming all the above:

That's a lot of machines!
Just for giggles, you would need 1,479 Engel machines to produce 200M parts in a year!
