Summary for pf zn 8c plating Discussion
PF ZN 8C plating is not clearly defined in the thread, so the key issue is identifying exactly what the customer means before processing the job. Ramesh Gnanasegaran asked for the procedure, base metal, coating thickness, salt spray limits for white rust and red rust, and whether the finish is hexavalent or trivalent. In reply, the answerer said “PF” may be an unfamiliar code or possibly a typo, and advised getting the exact substrate, specification number, required thickness, and chromate type directly from the customer or potential customer. The practical warning is that plating jobs can turn into contract disputes even when everyone understands the request, and confusion becomes much worse when the specification is unclear. No technical plating parameters were confirmed in the thread.

Hi Ramesh. It’s possible that “PF” is a code that I am unfamiliar with and which indicates some particular substrate … but it may simply be that there is at least one typo in what you wrote. Please find out from the customer or potential customer what it is that they want plated, what specification number they want it plated to, to what thickness, and what kind of chromate they want. Contract disputes are a commonplace even when everyone understands exactly what is wanted; when they don’t, it gets silly very fast :-)
Luck and Regards,
