Would depend on the specific model and part you are talking about. Most have parts of different material in them, so no single manufacture process will cover the whole thing, I think.
Don't really know much about it, you'd have to talk to a bicycle component manufacturer.

Perhaps you could put this exploded view of a derailleur in your assignment and then nominate the manufacturing process for each component. It seems possible to me that you could make a reasonable guess at the process for nearly all of the parts.
