Cyanide Copper Plating
Cyanide Copper Plating Services by Shree Kamakshi Industries
Cyanide Copper Plating, often referred to as a copper strike, is an electroplating process that uses a solution containing copper cyanide. It deposits a very thin, fine-grained layer of copper onto a component.
Its primary function is not to build thickness, but to serve as a protective, highly adhesive barrier between the base metal (like steel or zinc) and subsequent acidic plating baths (such as Acid Copper or Bright Nickel). This initial strike layer prevents chemical attack and ensures reliable bonding, which is essential for a defect-free final finish.
Key Benefits
The unique properties of the cyanide bath make it invaluable for specific industrial needs:
Superior Adhesion on Steel: It provides exceptional bonding directly onto steel and iron substrates, which can sometimes be prone to "immersion plating" (poor quality, non-adherent copper deposits) if plated directly into an acid bath.
Protection for Zinc Alloys: It is the preferred strike layer for plating zinc die-castings, as the alkaline nature of the cyanide bath prevents the acidic final layers from aggressively dissolving the zinc.
Corrosion Mitigation: The strike layer acts as a critical corrosion barrier, enhancing the performance of subsequent metal deposits.
Fine-Grained Structure: The thin layer deposited is dense and smooth, offering an excellent foundation for follow-up layers.
Applications
Undercoat for Steel: Used as the essential first layer before Acid Copper, Nickel Plating, or Chrome Plating on ferrous parts (steel, iron).
Plating Zinc Die-Castings: Crucial for components like automotive handles, brackets, and decorative parts made from zinc alloys, where robust adhesion is required.
Wire and Connector Industries: Used as a reliable strike layer before other functional finishes are applied.
Why Choose Us?
Safety and Environmental Compliance: We operate the cyanide copper process under strict controls and safety protocols, ensuring legal compliance and environmental responsibility, which is non-negotiable for this chemistry.
Flawless Process Integration: Our in-house, end-to-end process ensures the component moves perfectly from initial cleaning (Soapwash, Ultrasonic, Etching) into the delicate cyanide strike, guaranteeing optimal bonding for the final finish.
Expert Plating Lineup: As experts in both the strike (Cyanide Copper) and the subsequent build-up layers (Acid Copper, Nickel), we optimize the entire multi-layer system to meet your component's ultimate functional specification.
Reliable Foundation: We treat the cyanide strike as the most critical foundation layer, ensuring that expensive final plating finishes never fail due to poor initial adhesion.
