The impulsing power source enables precise pulse current modulation to optimize metal deposition, serving as a critical tool in modern electroplating. This technology forms uniform metal/alloy coatings (e.g., copper, nickel, chromium) via electrolysis, enhancing substrate properties such as wear resistance and conductivity. Key components include adjustable pulse waveform generators, cathodic workpieces, and ion-rich electrolytes, widely applied in automotive components, ABS engineering plastics, and PCB interconnects.
In automotive manufacturing, pulse plating strengthens wear-resistant coatings on engine parts while achieving mirror-finish chrome layers for decorative trims. For ABS materials, it overcomes traditional material limitations by bonding metal coatings to plastics without compromising lightweight advantages. In PCB fabrication, duty cycle adjustments ensure ±2μm thickness control for blind-via copper layers, critical for high-frequency signal integrity in 5G devices.
Integrated with High-Frequency Switching Power Supplies, pulse plating systems achieve over 97% energy conversion efficiency, reducing power consumption by 30% compared to conventional DC methods. For aerospace applications, microsecond-level pulse control forms nickel-tungsten coatings with <0.5% porosity on titanium alloys, enhancing oxidation resistance at 800°C. These advancements drive precision manufacturing in medical implants and microelectronics, where submicron coating uniformity defines product reliability.
Plating rectifiers support surface treatments like PCB electroplating, hard chrome coating, and metal plating (Cu, Ni, Zn, Au, Ag).

Protection Against Corrosion
– Shields metal surfaces from rust and chemical damage (e.g., zinc plating on steel).
Increased Wear Resistance
– Hard coatings (e.g., chromium plating) reduce friction and extend part life.
Improved Appearance
– Adds shiny, decorative finishes (e.g., gold plating on jewelry, chrome on car parts).
Better Electrical Conductivity
– Used in electronics (e.g., copper plating on circuit boards).
Enhanced Solderability
– Improves bonding in electronic components (e.g., tin plating).
Repair of Worn Parts
– Restores dimensions and functionality (e.g., rebuilding engine components).
Special Industrial Uses
– Provides heat resistance (e.g., nickel plating in aerospace).
– Used in medical devices (e.g., biocompatible coatings).
› 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
› Plating Solution
Contains ions of the target metal. Composition and concentration determine coating thickness, adhesion, and appearance.
› Plating Tank
› Rectifier
› Auxiliary Equipment
Air Cooling:Heat dissipation fan + air duct + comb heat sin
Water Cooling：Built-in water circulation line
