Electroless Nickel Plating

ENP Techno Engineers undertakes job-work of Electroless Nickel Plating (ENP), having over 25 years experience in the field and operating one of the largest job shop units in India. ENP a non-conventional plating system where current is not used for deposition. As no current is used, plating on intricate parts with hole 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. ENi has surface hardness of 48 to 62 HRC with excellent bonding and the plated layer does not flake-off. ENP is ideal for complex shapes where uniform and controllable plating thickness is not possible by conventional electroplating process, which makes it 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 ENi. Benefits at a glance: 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. ENP is the fastest growing coating for costly instruments and oilfield well equipments where very high corrosion protection and high surface hardness is required.
