well actually there are several ways to do the orifice
one is drilling it with some technology like drill bits of 0.10 mm or
go to a laser marking company who will drill the hole for you
another one is the ceramic/crystal approach where there are also
several companies offering specialized orfices in different sizes
going from 60 micrometers to 5 mm (this is the mostly used by
professional devices)
the third one is to use metalic tubing from medical or other
applications.
