Auto-catalytic nickel plating is referred to as Electroless Nickel plating (EN plating) using a heated solution. Best to heat the tank quickly, in about in 2-3 hours. We offer electrically heated designs for polypro tanks, stainless steel tanks and double boiler tanks.
All Welded Junctions Boxes keep humidity and moisture out on our 316 Stainless Steel and Titanium Heaters for EN plating.
Polypropylene tanks are the better choice for preventing the plate-out of the EN– be sure your tank heaters have a heat shield. To keep coating roughness to a minimum, continuous filtration of the bath is essential to remove materials. Be sure to monitor the temperature of the plating bath, too hot can speed up decomposition of the solution or cause blistering. A nickel plating heater that is too low could lengthen the process and prevent coating deposition. For more processing tips, view the Electroless Nickel Plating Heater info sheet.
Use an Industrial Heating Systems ABS air bubbler system for level safety. This sensor system is non-conductive and will not cause plateout in electro-less nickel plating.
