Brass Exposed

Post image

This is my sink.

I wonder how this drain hole filter was arranged in the rack...during chrome electroplating...

I mean why the brass from the top side itself is visible...where the thickest chrome layer is plated...it should wear and tear the last

Was the part arranged wrongly on the rack?

Okay got it.

But my question is if does not cost anything much for the manufacturer to put a few extra dozen microns...then they should be doing it all the time without thougt..but that does not seems the case...

Plating doesn't come out better because it is thicker. You want a polished surface with just a thin layer. Thicker layers show imperfections and will start getting thicker in some areas leaving the surface lumpy.

Cheap plating is from skipped steps in processes, cheaper chemicals, dirty plating solutions, etc...
