Summary for tin plating on copper lugs Discussion
Tin plating on copper lugs is the main topic, but the thread shows that the exact part form was unclear. Parin Sheth asked whether copper lugs should be polished before or after acid tin plating, and whether SS media or ceramic media should be used. Ted Mooney replied that, in general, most polishing is done before plating, but he cautioned that the media mentioned sounded more like blasting or vibratory finishing media than polishing media. He also asked for clarification on what “Copper Lux” meant and what kind of components were being plated. A later question from Mansoor Ali shifted to tin electroplating on “chain type lugs,” but no process answer was given; instead, the discussion again focused on clarifying the part geometry and whether it differed from strip or reel-to-reel plating. Overall, the thread emphasizes that the finishing method depends on the exact part form and process setup.
Q. Hi Friends , I have newly started my own electroplating plant. I deal in acid tin plating of copper lux^lugs metals. I have the necessary equipment but the problem now is I am confused as to when I have to polish/shine the copper lux^lugs metal? Is it before or after the plating procedure? Also, suggest which medias to be used — SS media or Ceramic media.
Advise me ASAP. Any valuable replies is greatly helpful to me.

A. Hi Parin.
Sorry, I don’t know quite what you mean by “Copper Lux”. Is that a brand name / trade name? I do see pot and pans, and also sinks, sold under that name. What kind of components are you tin plating and why?
Although most polishing is done before plating, it seems to me that the media you are describing are associated with blasting or vibratory processing rather than polishing and buffing. Please try to explain what you are doing for me. Thanks!

Q. Dear Ted Mooney,
Thanks for the reply.
As I am a bit amateur on tin plating process, my earlier post was a bit confusing. Now I know the whole process but am left with some more doubts. Hope you can help me out.
The polishing part that I was talking about was in a vibratory machine. And the MEDIAS are associated with it.
The material that’s gonna go into tin plating is COPPER LUGS (earlier was confused to COPPER LUX! my bad :))
Could you suggest me some LIQUIDS/SHAMPOOS that are poured into the vibratory machine.
Also, suggest which ones are better SS MEDIAS 202 or 304?
Awaiting for your reply.
Thanks Mate…

Sorry, Parin, but I don’t have much experience selecting media for mass finishing. We’ll have to await reinforcements unless you’d like to consult the Metal Finishing Guidebook which has an excellent mass finishing chapter which discusses selecting same. Good luck.

Q. Dear sir,
We are into tin electroplating onto lugs. We don’t have an issue while plating on loose lugs, but our client is asking for plating on chain type lugs. Now my question to you is how we can do it, and where can we get machine or equipment or any site which can help us.

A. Hi Mansoor. Your website says that you already operate strip plating lines, and reel-to-reel plating lines. Therefore I’m not quite understanding what you mean by “chain type lugs” if they are neither discrete parts nor reel-to-reel parts. Is there a photo or sketch of the form in which you envision plating these objects to clarify what you are looking for; or can you explain what makes them different from reel-to-reel components? Thanks.
