There seems to be very little machinery available for making small volume injection mold runs of your own. The industry has gone in the direction of large, expensive machines that can crank out lots of one design quickly, and then switch tooling to do the next guy's designs. This makes sense for contract manufacturing, but not for molding your own parts. That said, contract manufacturers are easy to work with. They'll do the mold design based on your CAD model of the object. Making the molds is the most expensive part.
