NICKEL PLATING HANDBOOK

For nickel plating, the electrolyte contains soluble nickel salts along with other constituents which will be discussed in the section on ‘Chemistry of Nickel Plating Solutions.’ When dissolved, the nickel salts dissociate into divalent, positively charged nickel ions (Ni++)

Nickel Plating - an overview ScienceDirect Topics

The nickel plating process has been modified to produce molds for the blow molding, thermoforming, and rotational molding industries. 1 The process begins with the part pattern, as described above. The parting line is defined and half the pattern, along with additional pattern construction of the parting line geometry, is carefully isolated from the other half.

Nickel Anode Forms and Their Use - STERC

2018-11-19  commercial nickel electroplating uses soluble anodes in a variety of forms and compositions. Forms commonly used are electrolytic squares, rounds, crowns, carbonyl pellets, carbonyl discs and solid bars. Electrolytic and carbonyl nickel anodes differ in the method used to produce them, chemical composition, and shape.
