Zinc plating procedure


 

What is the solution concentration that should be maintained in the solution bath for zinc plating? Also what is the pH and the electrical current in amps (at 220-240V at 50Hz)should be supplied? Please tell the procedure to be followed as we are planning to start an unit for electrical component plates.

We'd like to help Mr. Natesan, but a website like this is no substitute for getting a few plating handbooks for your library. Before anyone can recommend operating conditions for a zinc plating bath you need to tell them whether you intend to use an acid zinc chloride, ammonium chloride, mixed potassium and ammonium, cyanide, or alkaline non-cyanide bath. And before anyone can make a recommendation on that, they need to know more about your product and whether it can be barrel plated or not. Presumably your question about the 50 Hz power requirement refers to sizing the substation, and you realize that electroplating is done with low-voltage DC power?

You can get most all of this information from the chemical supplier's technical data sheets. You are using a chemical supplier, aren't you? You should also look up "zinc plating" in the Metal Finishing Guidebook. The guidebook is available through Metal Finishing Magazine.

Take the easy way out and learn through sub-contracting your work out to an able man. Everyone's doing R & D this way so it must be legal I presume!

I would like to know the chemical composition breifly of zinc plating process using sodium cyanide? Is there any standard chemical composition?

thanks

Laurnce, these are several somewhat standardized compositions, including low cyanide and mid-cyanide processes. Repeating myself, it also varies depending on whether you are barrel plating or rack plating. This is the kind of info you get from a trusted source like plating handbooks, that can cover the background issues. Old copies of the above-mentioned Metal Finishing Guidebook would be an ideal and inexpensive reference. Good luck.
