You can probably look at epoxy/composite tooling studies and have a better
fell for what you are dealing with. The insulating situation that you are
describing is very similar with epoxy tooling.

Additionally, the flow in these channels will be affected by the material
characteristics, by gating and venting in the tool, and by other design
aspects of the tool.
