The only problem with the chrome is it's all (or mostly) real metal. Putting metal on plastic requires time and equipment. They probably used some form of vapor deposition for a lot of it, and I can't replicate that right now, but electroplating is something I could do and something I'm looking into. It would produce, for all intents and purpose, an identical finish, but would require a cost increase on the parts vs no metal. I will try and make both versions of such parts available for those interested in one over the other.
Hinge seals should be no problem. Hinges themselves are a little much for the moment, but, and somebody correct me if I'm wrong, they're cast, right? Probably in Zamak with nickel plating on top? That's something I could replicate in the future if true. I'll look into it.
