Input voltage: Three-phase AC400V±10% 50HZ , Comply with national power quality standards
Output current: DC 5000A
Output voltage: DC 5V
Cooling method: Water cooling
Power supply type: IGBT-based
Application: Mainly used in industries such as electrolytic gas, electrolytic hydrogen production, electrolytic copper foil, electronic aluminum foil, rare earth smelting, PCB electronics, hardware electroplating, oxidation，
water treatment, etc.
Used extensively in manufacturing, electroplating applies micron-scale metallic coatings through controlled electrolytic reactions, improving both functional properties (e.g., abrasion resistance in engine components) and decorative finishes (e.g., jewelry gold plating).Widely used processes include copper, nickel, and hard chrome plating, with advanced systems like Polarity Reversing Electroplating Rectifiers enabling precise control for complex geometries. These rectifiers dynamically adjust current polarity, improving adhesion on ABS plastics and intricate automotive components.
The electroplating setup requires a cathode (substrate), anode (metallic or inert), electrolyte solution, and DC power supply. Modern Electroplating Rectifiers outperform traditional units by integrating bidirectional current control, achieving ±0.5% voltage stability for uniform chromium deposition. Their adaptive waveforms reduce hydrogen embrittlement in hard chrome plating while maintaining 98% energy efficiency, making them indispensable for high-volume PCB manufacturing and decorative gold/silver coatings.
In automotive applications, Electroplating Rectifiers optimize corrosion-resistant zinc-nickel alloy layers on engine parts, extending service life by 40%. The technology also supports aerospace fastener coatings, where periodic polarity reversal ensures micron-level thickness consistency. By minimizing material waste and process time, these systems exemplify innovation in sustainable surface treatment solutions.
Plating rectifiers support surface treatments like PCB electroplating, hard chrome coating, and metal plating (Cu, Ni, Zn, Au, Ag).

Enhance Wear Resistance, Conductivity & Reflectivity
Electroplating applies durable coatings (e.g., nickel or chromium) to surfaces, reducing wear from friction. This extends the lifespan of industrial tools and engine parts. For electronics, smoother conductive layers (like copper plating) improve current flow, minimizing energy loss. Metals like silver and chromium also boost reflectivity, ideal for mirrors, solar reflectors, and precision optics.
Improve Corrosion Resistance & Aesthetics
The process shields materials from rust, moisture, and chemicals. For example, zinc-plated bolts resist weathering, while chrome-plated car bumpers stay rust-free for years. Decorative finishes—gold-plated jewelry or matte-black plated gadgets—merge style with protection.
Dual Benefits
Electroplating isn’t just functional. It adds value:
Car parts gain sleek chrome finishes.
Circuit boards maintain stable conductivity.
Jewelry combines luxury with tarnish resistance.
Electroplating boosts both performance and visual appeal, making products last longer and look better.
› Copper Plating
Purpose: Enhances adhesion for subsequent layers and corrosion resistance.
Note: Prone to oxidation (forms non-conductive copper oxide/green patina). Requires protective coatings.
› Nickel Plating
Purpose: Used as a base layer or decorative finish; improves corrosion/wear resistance. Electroless nickel offers chrome-like durability.
Note: Magnetic properties limit use in electronics (e.g., DIN/N connectors) to avoid signal interference.
› Gold Plating
Purpose: Optimizes conductive contact impedance and signal transmission.
Key: High stability but costly.
› Palladium-Nickel Plating
Purpose: Superior signal transmission and wear resistance vs. gold.
Advantage: Combines palladium’s corrosion resistance with nickel’s hardness.
› Tin-Lead Plating
Purpose: Improves solderability.
Trend: Phased out due to lead concerns; replaced by bright/matte tin alternatives.
› Silver Plating
Purpose: Best conductivity and signal performance.
Note: Conducts even when oxidized but tarnishes over time. Higher cost.
Selection Criteria
Match plating type to application needs: corrosion/wear resistance, conductivity, cost, and environmental regulations.
› Cathode
The object to be plated (e.g., connector terminals or metal surfaces) where metal ions deposit into a solid coating.
› Anode
Soluble Anode: Made of the plating metal. Dissolves during electrolysis to replenish metal ions in the solution.
Insoluble Anode: Used for precious metals (e.g., white gold, iridium oxide). Does not dissolve but supplies electrons for reduction.
› Plating Solution
Contains ions of the target metal. Composition and concentration determine coating thickness, adhesion, and appearance.
› Plating Tank
Materials: Must resist corrosion and temperature fluctuations (e.g., polypropylene, titanium alloys).
Role: Stores solution and maintains stable plating conditions.
› Rectifier
Converts AC to DC power to drive electrolysis.
Adjust voltage/current to control deposition speed and coating thickness.
› Auxiliary Equipment
Filters: Remove impurities from the solution.
Heaters: Maintain solution temperature.
Stirrers: Ensure uniform mixing.
Air Cooling:Heat dissipation fan + air duct + comb heat sink
Water Cooling：Built-in water circulation line
