I had the same problem with insect molds that I was trying to pour. What I did was, I got 2 pyrex cups the first one was used to heat the plastic in the microwave. The 2nd one was used to pour the baits, but on this one I took a metal cake frosting tip and attached it to the spout of the pyrex cup with epoxy. This will give you a very small, precision flow. Just don't put the metal tipped cup in the microwave or else fire works!!! Ha ha hope this helps.
