Plating on plastics-Plastic forum


#1

Hi Bill

I finally managed to solve my problem.

I have settled on layed plating. The results are astounding.

1.I make the surface conduvtive with my own concotion of
conducting paint.

2.Layer it with copper by a bright acid copper bath.Depending on
the object different micron deposits produce the required shine.

3.Silver plate the object. Usually a bright shiny surface is
obtained with 2/3 microns. But I plate to the required micron
deposit to obtain a reasonable deposit as the objects are for
decorative purposes. Although I have started I still have a long
way to go as far as the ;learning curve is concerned.

Any help and suggestions on the copper plating/shiny surface of
copper and silver durability of the shine would be appreciated.
I am unsure if any copper would diffuse and showup on the silver
surface and ruin the silver coat after passage of time?

Thanks.

Rajah

Rahaj It is possible that the copper will bleed through or
tarnish below the surface of the silver. It is customary to
nickel plate under the silver to prevent such things from
happening. Michael
