I've done much overmolding in my time, but I have a strange request for a promotional product for a new customer. We have been molding a "roof scupper" for them in TPO (I'll update this thread with the grade tomorrow...can't remember at the moment). Well, they want to make a TPO chip with a flexible PVC ring to demonstrate the materials they use. Now, I know I can mold the chip with anchors for the overmold, but I haven't been able to find any compatibly charts for TPO - fPVC (not that it really matters, its not a functional part). Has anyone overmolded these two?

Thanks,

P.J.
