Our premier selection of industrial electroplating formulations. Engineered to optimize corrosion performance, ensure uniform thickness, and support sustainable environmental compliance.
Electrolytic zinc coating, widely referred to as electro-galvanizing, represents a foundational cornerstone in high-volume, precision anti-corrosion science. Utilizing controlled electrical currents inside specialized aqueous baths, our technologies deposit micro-refined, uniform layers of metallic zinc onto ferrous substrates. This sacrificial layer intercepts oxidative environments, shielding base steels or alloys from early degradation.
Traditional industrial coatings often struggle to balance thickness uniformity and environmental safety. As a leading manufacturer of organic chemicals, Suzhou Hiyie Chemical Co., Ltd. addresses this paradigm by offering advanced alkaline cyanide-free zinc formulations, zinc-nickel alloy chemistries, and high-performance trivalent passivations. Our solutions ensure superior mechanical fitment, controlled friction coefficients, and prolonged salt spray endurance (NSS up to 1000+ hours) while satisfying RoHS and ELV criteria.

Modern industrial specifications demand high corrosion performance with thin deposit profiles to maintain tight mechanical tolerances. Standard acid zinc plating deposits can exhibit uneven distribution across complex geometries. To resolve this, alkaline zinc and zinc-nickel alloy plating processes are utilized:
Alkaline systems provide excellent throwing power. By removing cyanide compounds, Suzhou Hiyie's 8315 Alkaline Cyanide-free Bright Zinc Plating provides a uniform deposit profile across complex recesses, avoiding heavy build-ups on sharp edges. This ensures consistent dimensions for threaded components, stamping assemblies, and fasteners.
For harsh operating environments like automotive under-the-hood or marine structures, standard zinc coatings can prove insufficient. Our 6185 Alkaline Zinc-Nickel Plating deposits a structured gamma-phase alloy containing 12% to 15% nickel. This configuration exhibits high thermal resistance (up to 200°C) and limits galvanic corrosion when paired with aluminum components.

Providing specialized surface treatment chemistry for global manufacturing supply chains.
Brake systems, fluid transfer connectors, and engine fasteners require high corrosion protection. Utilizing ZN-318 Blue Trivalent Zinc-Nickel Passivation maintains barrier protection even after exposure to thermal shock.
Providing thin-film coating formulations that fit shielding enclosures and internal brackets. These coatings maintain electrical contact paths and prevent zinc whiskers from forming on electronic parts.
Tooling fixtures demand clean, chemical-resistant finishes. Our J0-1 Ultra-Low Phosphorus Electroless Nickel provides uniform deposition inside deep recesses, defending components against acidic process environments.
Procurement divisions face strict compliance challenges. Standardizing raw materials requires chemistry that conforms to environmental regulations while maintaining process stability across high-volume production lines.
Due to global restrictions on hexavalent chromium (Cr6+), using trivalent chromium passivations is essential for exporting components to European and American markets. Hiyie’s trivalent passivations, such as our 216 High Corrosion-resistant Iridescent Trivalent Zinc Passivation, offer high corrosion resistance while eliminating toxic waste streams and reducing effluent treatment costs.
For high-tensile fasteners, electroplating must avoid hydrogen embrittlement while maintaining a controlled torque-tension relationship. Formulating our chemistries with post-dip sealers allows clients to achieve a consistent friction coefficient (typically 0.12 - 0.15) to prevent galling and ensure reliable fastening torque.
