How are these smartphone back covers made?
The plastic is polished black, the logo and text is reflective silver grey. I’m interested in replacing with a custom made cover, but I don’t know the process that was used to achieve this. I have found out that they most probably used laser etching for my iPod, but I can’t find anything on this. Thanks.
Update: I found an Ebay listing with the logo half scratched off, confirming my assumption of it being somehow printed on. I still don’t know how though, haha.

my guess would be double shot injection molding, like high end key caps?
I found some examples, the key caps you mentioned, made with two-shot injection moulding but the text on them looks imprecise and has rounded corners. The iPhone back cover has really precise and sharp text. The small text is also probably too small for that method.
The apple logo is probably two-shot moulded, the text is definitely printed.
