They're also doing some interesting stuff in plastics, such as in-mold
decorating, insert molding and something called "In-Mold Assembly" that
originated in Germany (see "Job Shop Technology," October 1998 issue). It
uses multi-shot injection molding. "The first shot produces a pre-form- the
second (sometimes third or fourth), the finished part." If you want the
parts to move, you just use a material with a lower molding temperature on
the later shot.

There was a zinc die casting process by Gries Reproducer in NY that was
able to make a swivel clevis in a "single two-stage process". That means
the clevis was cast around the swivel and it came off the machine as a
complete part. Very close tolerance between the two parts and very
repeatable. It was really kind of neat, in a low tech way!
