From what I understand of industrial injection molding, the pellets are usually melted by frictional heat as the screw turns, not by external heaters

I assume you've seen these? [www.techkits.com]
Would this limited run be sold as an actual product, or just used for consumer testing?
Also, it might be easier to build a CNC machine to make your own molds and a DIY injection molding machine to inject with than try to use an FDM mold.

The ones I have seen use heating elements attached to the screws housing. I was recently at an o ring manufacture and all their injection machines have them (most were old 80's or so models) , maybe new machines use friction heating?

I do not know if this will work but anyway - Print a hollow prototype. Mix ABS pellets and acetone to a consistency that can be injected or poured in the hollow prototype. Dry out the acetone by sucking it out in a vacuum chamber. Maybe worth a try!

Intresting thought. I'm not sure that the acetone would be removed independent of the ABS. I think the vacuum would act upon the solution of abs/acetone, not on the acetone itself. I think by pushing or pulling air around it you help it dry, but with vacuum I think you'd just destroy/deform your pour.
