As a result of the investigations performed in specialised laboratories, we started to design plants based on the principle of electrochemical deposition of some hard metal layers (nickel, nickel-alloy).
Special electrochemical solutions for nickel and nickel-alloy plating were prepared, having a well-defined composition and parameters kept, in strict limits resulting in the achievement of hard and thick layers (nickel 300 μm approx. and nickel-alloy 1 mm approx.).
The technology of reconditioning the mould plates by nickel and nickel alloy coating includes operations for the preparation of plate surface (cleaning, pickling), nickel and nickel alloy tanks, special devices for solution stirring, delay of dendrite for occurrence on the plate corners and edges, solution recirculation system, power supply sources, electrical and steam system for solution heating.
