The bond is actually stronger than the plastics, so under a huge amount of stress theoretically one of the plastics would tear apart before the bond did.
Really? They are doing a pretty simple overmold. Plastic loves being round. Grades of materials would have to be matched up to get similar melt characteristics, but seems pretty easy to me.
