electroplating costs calculation - polynet

material's cost has a large influence on the total process' cost only for gold-plating or other technical precious metals (not very common applications). even if silver is a quite expensive material for small and medium parts material cost doesn't have any large influences on the global cost of the plating process because labor is much more costly.
