We have been asked to chromium plate some dies used for injection molding. If we do it correctly, we anticipate receiving additional jobs in the next 12 months. What thickness of chromium should be applied? Are there any other things we should be aware of? R.M.
I assume you are already versed in the “fine art” of chromium plating so a straightforward answer is in order. The chromium thickness that is usually considered adequate is in the range of 0.0003 - 0.0004 inch. The other major item you must be aware of is that most dies used for molding have complex shapes and require the use of conforming anodes to obtain reasonably consistent deposit thicknesses.
