A. After mechanical pretreatment you would need to soak clean, acid activate, neutralize, cyanide copper strike, cyanide copper plate, and then tin plate or brass plate. Contacting a supplier of plating chemistry would probably be a good first step if you need to do this in-house, and contacting a plating shop might be a better idea still.

Electroplating is a highly complex process which people spend decades learning ... so we can offer a general process sequence as I did, and we can answer very highly specific questions, like what is a good current density range for cyanide copper strike but explaining the whole process in sufficient detail for you to get "good results" just isn't very realistic. But good luck!

What is the process sequence to manufacture zippers and get good results?
