Part Numbering after a surface finish

[RustyH]

Hello All,

I was wondering how you all manage your part number if you potentially have a product sitting on a shelf unplated, and the same product plated. Do you have a serperate part number for the unplated one. Send it out for plating, then book it back in as a different part number?

Every significant step in the manufacturing process has its own p/n - casting/forging, machined part, assembly, on up to final saleable part. The division of p/ns depends on what makes sense for the given part, and in many cases you may want to assign a p/n to denote things such as a part level leaving each facility or supplier. Paint and coatings are the same, uncoated is one p/n and each variation of coating/painting another. Typically each does not need its own print however, simply a charted single print calling out each p/n.

We would add a a suffix to the part number for finish (12345P would be prime only, 12345 would be unfinished, 12345A would be green, 12345B would be blue...)and maintained in a tabulation on the 12345 drawing
