Thermo-mechanical simulation injection molding

I'm trying to simulate the stress of a duroplast part coated in thermoplast. Therefore I set the strain reference temperature to 240°C (process temperature, injection molding) and cooled the part down to 25°C. The problem is that the stress is way too high on many areas (about 2000 MPa, while thermoplast breaks at 210MPa).
The thermoplast I use is Polyamide 66 with 35% glass fibre reinforcement.
What mistakes did I made in my model? If the stress were always high like this, no thermoplastic part would work after injection molding.
