Being a non-conventional plating system, the Electroless Nickel Plating, which we render, doesnt use current for deposition purposes. The Electroless Nickel Plating Service, we render, helps in getting intricate parts with deep recesses and holes, or uniformed layer thickness; resultantly minimizing excess build-up, if any, on the edges or corners, eliminating the post-plating grinding operation. The Electroless Nickel Plating Service produces an amorphous layer, having exceptional resistance against corrosion and uniform thickness of the deposited electro-nickel material. This Electroless Nickel Plating Process is best suited for taper cavities, spiders, breakers plates, plastic dies and other varied extrusion die parts.

Fasteners are not small parts in engineering equipments. They play a big role in proper functioning and success of costly equipments. Properly designed fasteners reduce risk of premature failures and also risk of warranty claims and service calls. We offer the world class coating facility for fasteners. We offer following coatings:

• Zinc Flake Coating
• XYLAN/PTFE Coating
• Electroless Nickel Plating
• Black Oxide Coating
• Phosphating

Zinc Flake coating is a new technology for fasteners coating. We have got technology from US based Magni Corporation. The innovative micro layer coating system offers high grade of corrosion protection, 240 hours to 2000 hours SST. The coating offers Cathodic Protection and is also excellent resistance to chemicals and temperature. Please refer to themagnigroup.com for more information. Zinc Flake and Xylan coatings are applied by dip spin technology or by spray technique. The coating is totally free from Pb-, Hg-, Cd- and Cr(VI), RoSH compliant and environmental friendly process. The coating is free from Hydrogen embrittlement, no chance of premature failure/cracking. This coating is heat resistance and engineered with integrated friction modifiers to eliminate the need for sealer or post coating lubricants and ensures repeatable torque/tension characteristics in assembly. Corrosion protection and secure threaded fastening capacity through adherence to defind coefficients of friction are ensured by the use of a micro layer coating system. Zinc Flake coating penetrates in small gaps, in internal area of pipes and offers superior corrosion protection where electroplating is not possible. Various top coats are available for higher gloss, improved corrosion protection or for different colors for identification. The post coating curing process is done at low temperature and therefore softening of the hardened steel parts is prevented. These products find applications in gas turbines and power generation, in construction, in ship-building and marine engineering, in pressure vessels, nuclear plants, in railways, in automobiles, in air coolers and boilers, in off-shore and on-shore projects, in chemical and petrochemical plants, in industrial equipments and in high cost consumer durables.
