Electroless Nickel Plating - Superior Surface Finishing

Welcome to Greystone, your trusted partner for high-quality Electroless Nickel Plating (ENP). Our expertise in Electroless Nickel spans various industries, including Automotive, Aerospace, Medical, Defense, and Industrial applications. With a proven track record and a commitment to excellence, we offer the reliability and precision for your surface finishing needs.

Understanding Electroless Nickel Plating

Electroless Nickel Plating is the deposition of a nickel-phosphorus alloy onto a metal substrate. What makes this process unique is its autocatalytic chemical reaction, resulting in a coating of uniform thickness that often eliminates the need for post-plate grinding. Greystone's Electroless Nickel Plating demonstrates excellent corrosion protection, with lubricity properties similar to electroplated chromium. Our electroless nickel plating process effectively coats parts with sharp edges, deep recesses, seams, threads, and complex geometries.

Electromagnetic Shielding with Electroless Nickel

Electroless nickel renders itself non-magnetic, making it the optimal choice for electromagnetic shielding. Our plating process can be applied over a variety of substrates, including steel, stainless steel, aluminum, copper, brass, and many proprietary alloys.

Investment in Reclaiming Nickel for 100% Recycled Chemistry

As part of our sustainable practices, Greystone made significant investments into reclaiming nickel from spent Electroless Nickel plating solutions.

By reclaiming and reusing nickel, we minimize the need for new raw materials and reduce waste generation. This initiative represents a major step towards a more circular and sustainable approach to electroplating.

Greystone's Commitment to Excellence

Greystone - Induplate utilizes custom barrels and part-specific racks, internally designed to accommodate even the toughest geometries. Our automated inspection and sorting machines eliminate common plating defects, ensuring top-quality results. Whether you have job shop orders or high-volume production (1-30 million parts), Greystone has the staff and resources to meet your needs.
