    As said before, plastic molds must be polished to a mirror like finish, or it would reflect any imperfections. Even in small production line which i assume you thinking about it would take a lot of time to hand finish every single piece. However hand finish would not be as good as from a good mold. Anyway don't take me a wrong way, I do a lot of things the hard way myself before i learn to make it wright, which most of the time equals that my trying to save the money, costs me twice as much.. if you know what i mean. I do know some small manufacturer in Europe who specializes in plastic mold making. Economy is tough these days and if you have a part drawing i can put you in touch with them for a quote. I am not trying to advertise here or make money of you.
    Just suggesting... Best regards Mike

    And as a former moldmaker I can assure you there is no job more tedious and miserable than polishing, especially with an optical finish the goal.

    If it's short run stuff, you could always polish the plastic.......
