Ecologically state-to-art hard chrome plating system

We give our client’s disposal state to art hard (industrial) chrome plating technology which uses the Precision Plating System®.

One of PPS® characteristics, is the high quality of plating (galvanizing) achieved (Cpk>1,67, PPM: 0-1) affecting minimizing the scrap level during the production process. It is essentially important when there are logistical problems with buying of raw materials. Also, the main parts, that are assembled using hard chrome plated components are of the highest quality possible.

Thanks to Greystone’s Precision Plating System®. parts are electroplated in an eco-friendly way (external emissions are close to zero – closed system). There is no need of replacing the hard chrome (anodize) coatings, which provide unparalleled performance to other coatings for highly engineered applications.

    Selective plating of Electric Vehicles(EV) motors parts.

    Electric motors could reach speeds above 20,000 rpm that is why EV engines should be produced using the best technology available. This applies to all materials and parts used inside the electric motor. Especially rotor and stator have to be extremely strong to keep them from flying apart.

    Greystone selective plating technology could allow to use less rare earths. From the design level: thanks to the Precision Plating System® we could plate the parts directly where it is obligated. For instance, the magnet surface could have a coat only on the areas where it is needed. Greystone’s innovative engineering allowed galvanizing the parts using an integrated automation system with high-quality requirements: PPM: 0 – 1, Cpk > 1,67.

      What is the best electropating anti-corrosion protection available?

      According to Greystone customers – Infinity™ coating, which was developed by us and is our proprietary plating technology. The Infinity™ layer is successfully used by our customers on products that are used in the most adverse conditions. One such environment is a salty aquatic environment. Ship fasteners that are coated with Infinity™ will shine most of the time.

      The Infinity™ protective coating ensures that the parts covered with it withstand the salt spray test for up to 4,000 hours before the first signs of rust appear. It is more resistant to rust compared to products made of stainless steel, without any protective coatings.

      Infinity™ is a coating used on products with severe/extreme usage conditions. It can also be successfully used on other components such as: BiPolar plates, pump elements, fuel pump components, etc..

        How big is micron / micrometer

        What is the thickness of galvanic (electroplating) coatings? The answer is obvious: very small, measured in microns / micrometers:

        • about 4.5 μm: the typical thickness of the Hard Chrome layer
        • about 10 μm: the typical thickness of the Zinc-Nickel layer

        Please use the below drawing to compare the sizes.

        Electroplating coating thickness depends on what the customer’s requirements are. At Greystone, we have the right technology and experience to meet any project-related challenges.

            Very precise hard chrome lining of gun barrels

            The Greystone company is specializing in electroplating elements of firearms. Our plant, located in America, since 2008, provides this type of service. It should be remembered that in the United States of America, gun ownership is so widespread that, according to statistics, there are 120.5 firearms per 100 inhabitants (source: https://en.wikipedia.org/wiki/Gun_ownership). As a result, the demand for high-quality electroplating services is growing every year. Therefore, Greystone is very experienced – it has been Hard Chrome Lining Gun Barrels for over 14 years with more than 1 million barrels chrome lined since 2008. That number makes a difference in knowing the technological aspects of work.

            We offer to our European clients the knowledge and superb quality acquired over the years in the American market. Our experience and refined processes are a perfect fit for almost every firearms / gun’s manufacturer (for every system on the market, for instance like AR16 or AK47 type) requiring tight dimensional specifications, stringent quality requirements, and high-volume production capabilities. As a full-service single source market leader in Hard Chrome Lining Gun Barrels, Greystone has mastered the ability to consistently deliver superior products on time for our clients.

            Our expertise provides, among others:

            • Exceptional accuracy with uniform chrome thickness extending throughout muzzle crown
            • Proven capability to meet .0004" (10 microns) minimum, consistently throughout the barrel
            • Durable chrome lining for maximum endurance & extended lifecycle of barrel
            • Crack-free character inspected at 100x magnification for corrosion resistance
            • Improved lubricity for effective cleaning of gunpowder residue
            • Enhanced heat dissipation in high rate of fire conditions
            • Optimized bore surface with reduced coefficient of friction to combat copper fouling
            • Prolonged life of the barrel
            • Reduced wear
            • Enhanced corrosion resistance
            • Our highly engineered process that yields industry leading control of chrome thickness on lands/grooves, and in chamber. Head space tolerances are consistently maintained

              Is a plating process possible with Cpk> 1.67?

              The described “actual process capability factor” – Cpk informs about the accuracy of manufacturing of a given part. This is a very important parameter, especially in mass or large-scale production which takes place at the Greystone Poland plant in Stalowa Wola. The higher the Cpk value, the lower the risk of producing a defective product. The worldwide standard of customer requirements for manufacturing companies is that the production process has a Cpk value> 1.33. With such a factor, the defectiveness of the manufactured parts is about 0.0063%.

              Thanks to highly qualified employees and a modern production line, the plating process carried out in Greystone Poland in Stalowa Wola is very accurate and its: Cpk> 1.67. It is an added value that all our clients receive. Thanks to this, we minimize the resulting waste and costs, as well as obtain a final product of very high quality.

              Typical PPM (Parts Per Million) in our factory is 0 – 1. Is it a lot or a little? Faulty parts (out of a 1 million produced) are marked in red in the attached photo.
