Conductive Paths on Polymer

I'm looking for a finishing process that can be used to put on conducting paths on polymers in one step. I have been looking at some conductive paints, but in order to achieve a conductivity suitable for signal transfer and possibly small power (up to 1 amp.) transfer. Most paints I have seen need some plating afterwards to achieve real conductivity. The purpose is industrial use in the amount of ca. 500000 pieces a year.

Have you tried silver paints ? A nominal thickness of 20-25 microns should provide sheet resistance of less then 0.01 ohms per square.A vacuum deposited layer of aluminium to a thickness of 5 microns could also be a suitable alternative.
