A little free time on my hands today got me day dreaming about making soft plastics.  Granted, I've never poured a worm in my life but I'd like to.  I'm wondering how the big boys make their stuff.  Is the plastisol injected into the mold then heated or heated first like a hand pourer would do?  I've searched the web for mold makers but only come up with Delmart and Bob's.  Anybody know who makes the multi cavity injection molds used for larger production runs?

Magic!

Actually I have no idea how they do it but I would suspect injection molds.
