We had very good luck using BJB two part polyurethane for low production (<1000 year) large parts. There's quite a bit of process engineering required, but you can get fantastic results, and relatively fast die cycle times, without breaking the bank.

Does BJB have some additives so the PU is non flamable? (ul 94 v2 comes into mind)

I believe they do, although it's not a something I have used personally. They have a pretty comprehensive catalog [1], but like most things with adhesives and resins I would just talk to an application engineer about requirements. Haha, I wish they'd had such a comprehensive catalog when we started working on our parts, because we were left to figure out a lot of it for ourselves.
