Chrome Electroplating Rectifiers serve as core equipment in electroplating processes, utilizing electrolytic deposition for surface treatment. This technology enhances wear resistance, conductivity, and corrosion protection on both metallic and non-metallic substrates. The system comprises four essential components: cathode (workpiece), metal/inert anode, electrolyte solution containing target metal ions, and a DC power supply with ≤3% ripple factor. Modern rectifiers employ high-frequency switching technology, achieving ≥92% energy conversion efficiency and adjustable current density (0-120A/dm²). Applications span automotive components, ABS plastics, and PCB multi-layer plating (Cu/Ni/Cr), accommodating functional coatings (10-300μm) and decorative finishes (0.1-1μm) with precision control.
Plating rectifiers are widely used in surface treatment applications. They support processes like PCB electroplating, hard chrome coating, and plating with metals such as copper, nickel, zinc, gold, and silver.
Characteristics of an electroplating rectifier:
› Excellent Energy-Saving Effect:
The rectifier is designed to operate efficiently, converting incoming AC power into DC power with minimal energy loss. This leads to significant savings in electricity consumption, which can be particularly beneficial for large-scale electroplating operations that require continuous power supply.
› High Output Stability:
The rectifier is capable of maintaining a constant and stable DC output voltage and current, even under varying load conditions. This ensures consistent and uniform plating thickness, which is crucial for achieving high-quality electroplating results.
› Flexible Output Waveform Modulation:
The output waveform of the rectifier can be easily modulated to suit different electroplating processes and requirements. This includes adjusting the pulse width, frequency, and duty cycle of the output waveform, which can optimize the plating efficiency and quality for specific applications.
› Ease of Waveform Modulation:
In addition to flexibility, the rectifier is also designed for ease of waveform modulation. Operators can quickly and accurately adjust the waveform parameters using intuitive controls or automated systems, allowing for precise control over the electroplating process.
Overall, these characteristics make the electroplating rectifier an essential tool for achieving high-quality, efficient, and energy-saving electroplating processes.
Enhance Wear Resistance, Conductivity & Reflectivity
Electroplating applies durable or conductive layers to surfaces, boosting friction resistance. Smoother surfaces improve electrical flow in components. Metals like silver/chromium increase reflectivity for mirrors and optical tools.
Improve Corrosion Resistance & Aesthetics
The process shields materials from moisture, oxygen, and chemicals, prolonging lifespan. Decorative finishes (e.g., chrome car parts, gold jewelry) add elegance while protecting surfaces.
Electroplating combines functional upgrades with visual appeal, extending product lifespans through both protection and design.
› 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.
The plated object (e.g., connector terminals or metal surfaces) receives the coating. Metal ions deposit here during reduction.
› Anode
› Plating Solution
Contains target metal ions. Its composition and concentration determine plating quality (thickness, adhesion, appearance).
› Plating Tank
Holds the solution, requiring corrosion resistance and temperature stability. Materials must withstand chemical exposure.
› Rectifier
Converts AC to DC power. Adjusting voltage/current controls deposition speed and layer thickness.
› Auxiliary Components
Air Cooling:Heat dissipation fan + air duct + comb heat sink
Water Cooling：Built-in water circulation line
