1. The plating solutions are completely free of cyanide, safe and environmentally friendly.

2. The plating coating is uniform, and appears golden color. The color can be adjusted through adjusting

the percentage of copper and tin.

3. Both rack plating and barrel plating are OK, it can be used on pre-plating, thickened plating and
