What is an acceptable thickness for chrome plating ABS parts?

January 31, 2008

I have a simple ABS plastic part that needs to be Chrome plated. This part is a ring that will be captured between a Top and Bottom housing (not plated). I am using a tongue & grove feature to hold the three parts together.
My question is:
how much gap should be left for the Chrome plating, if I am going to have a good fit between the three parts ?
ONLY the ring needs to be Chrome plated?
I will appreciate your help.

Assuming that this is decorative nickel-chrome rather than functional hard chrome, service condition moderate, Mohammad, the thickness of the plating will be about 0.0004 to 0.0006 inches.
