For those of you that are interested in how the injection molding process works.
I have found a couple of good links that explain and show how things work.
I was going to put a page together myself, but these links do a better job than I ever could. One of these days, I might suppliment things with some pictures of our machines and mold where I work

This first link is a good basic overveiw of how things work. It explains things pretty good and has a few pictures

This site has a more in-depth and detailed explanation. Complete with diagrams.
