How to pour recycled PET?
(OP)
I have a small design firm in L.A. and we are looking for the most economical & efficient way to melt, pour & cast recycled plastics (regrind) into flexible silicon molds. Injection molding will not work for our application. The final product will fit in the palm of your hand, with numerous undercuts. Off-the-shelf casting resins work, but we are looking to use recycled materials for our final product. Thank you.

PET is not suitable for casting in rubber molds. Sorry to rain on your parade!

I understand that Injection is not suitable because of undercuts, try using split cavitiy moulds.
If witness lines are a problem you can consider polishing as a second operation.
