Silver lends itself well to electroplating due to its unique properties, which are unlike many other metals. People have used this material for centuries
across numerous industries — and for a good reason. The material's defining characteristics combine to create a metal that's durable, cheap and
hardier than the rest when operating within diverse industrial applications. If you're looking for a cost-effective plating solution, silver is a top choice. By
emphasizing quality and function, this metal has earned a valuable space among popular metals used for plating.
WHAT'S THE SILVER PLATING PROCESS?
The silver plating process steps are relatively straightforward, although they differ depending on what type you're doing — barrel or rack plating. The
basic strategy, however, goes like this:
- Inspection: Before electroplating, you should always check the part for imperfections — like cold shuts or sharp edges — and amend these issues
before starting the process. Otherwise, the quality of the substrate will decrease, and this may cause problems for your customers.
- Pre-treatment: Complete any necessary treatments before plating onto your metal part. You should also do an under-plating of copper, nickel or both
metals. Additionally, you can add a silver strike or an anti-tarnish coating if there's a particular effect you want to achieve. If you plate a layer of
nickel or copper with a 0.0005-inch thickness, the silver should also be 0.0005 inches for a total of 0.0010 inches.
- Electroplating: Silver plating involves submerging the substrate into a bath of silver ions. After passing an electric current through the solution, the
ions deposit onto the part's surface, coating it in your chosen metal — in this case, silver.
