Electroless nickel plating
Nickel protects all your mechanical parts from corrosion and wear.
Our chemical process (formerly known as KANIGEN) allows the treatment of complex parts and to modulate mechanical properties to your requirements.
Unique in Europe, our line is fully automatic: it is capable of simultaneously and immediately treating any type of material thanks to its “smart” control.
ISO TS 16949 (and therefore ISO 9001) certified, we can guarantee perfect traceability and reliability.
We have the capacity to nickel plate parts up to: 2000 x 1000 x 800 mm, 1.5 tons.
Electroless nickel plating specifications
Verbrugge, an expert in chemical nickel plating , uses the KANIGEN process for the surface treatment of metals, even for the most complex mechanical parts. Low , medium or high nickel, choose the method that best fits your needs. To help you in your choice of surface treatment by nickel plating, see our data sheet which reviews all the technical features of the KANIGEN technique: corrosion protection, hardness, electrical resistance, etc.
