737 nickel-free black nickel electroplating Plating chemical
737 nickel-free black nickel electroplating Plating chemicaltechnology is a nickel-free, nontoxic,tin-cobalt alloy electroplating processing. The coating’s color of this process can be black and bright. It’s good hardness and easily controlled color and stable plating bath made this technology suitable for every kind of black decorative electroplating.
2,Process features
a,Special beautiful black coating, the color can be selected from light black to deep black..
b,Stable electroplating bath ,wide range of technology, also stable coating color.
c,High coverage capacity, especial for barrel electroplating
d,Don’t need wastewater treatment.
e,Can be plated on bright copper ,white-colored copper/tin alloys,brass
3,Equipment
Coating bath: rigid PVC or steel bath covered by plastic.
Heating : titanium or quartz electric pen.(You’d better use the water bath to heat uniformly)
Anode : carbon board
Anode bags: needed
Mixing: cathode rocking, at least 1~2 meters in one minute or liquid flow. Using the air in stirring is not allowed.
Filtering: continuous filtering.
Barrel plating: regular semi-auto portal line, its conductive should be good, or the walk position will be difficult.
