Electroless Nickel Plating
Electroless Nickel Plating
Electroless Platers undertakes job-work of Electroless Nickel Plating on various parts. Electroless nickel plating is a non-conventional plating system where current is not used for deposition. As no current is used, plating on intricate parts with holes and deep recesses can be done with a uniform layer thickness. There is no excess build-up at edges or at corners and hence eliminates post-plating grinding operation. The plating layer is amorphous and corrosion protection is superior to that of equal thickness of electrodeposited nickel. It has surface hardness of 48 to 62 HRC with excellent bonding and the plated layer does not flake-off. Electroless nickel plating is ideal for complex shapes where uniform and controllable plating thickness is not possible by conventional electroplating process. This makes the process most suitable for plastic dies. The company regularly plates taper cavities, breaker plates, spiders and other extrusion die parts. Barrels for injection moulding machines are plated for non-stick property and for easy cleaning. Worn-out punches can be re-build to original dimensions by uniform coating with electroless nickel. This makes the process superior to electroplating. This plating process can be done on selective areas also. Small parts difficult to plate individually, can be hard plated in a barrel. The plating layer can be buffed to mirror finish. Benefits: superior corrosion protection; uniform and controllable layer thickness; wear resistance high surface hardness; non-stick property for plastic moulds and extrusion dies; and solderability, ductility and lubricity.
