We happened to be touring a factory in Billund on a day when they were
making dark gray chains -- in fact, we brought some home, literally hot out
of the machine. That said, we have no insights into the mystery of how they
get formed except to say it was done with the same standard machine that
common bricks are made with and that it appeared to be doing the usual
steps: close, inject, open, eject and taking the usual amount of time per cycle.
If someone figures it out, we'd like to know too!
