Power supply type: IGBT-based power supply
Application Industry: Surface treatment industry, such as hard chrome, zinc and copper plating.
In an ±15V 12500A hard chrome plating rectifier power supply, after the AC input voltage is filtered by a rectifier circuit, high-voltage DC power is obtained. The “variable frequency conversion” stage inverts this high-voltage direct current into approximately 30kHz high-frequency alternating current. This high-frequency AC is then transformed into secondary voltage via a high-frequency transformer and filtered through a high-frequency rectifier circuit to produce the required output voltage. The electroplating rectifier power supply employs a control circuit to sample output voltage and current. These sampled signals undergo closed-loop feedback to generate pulse width modulation (PWM) signals, which regulate the inverter circuit and maintain stable output voltage/current – a critical requirement for precision electroplating applications.
Manufacturers widely use electroplating rectifier equipment for various surface treatment applications, including PCB electroplating, hard chrome coating, copper plating, zinc plating, gold plating, tin plating, nickel plating,and silver plating, among other metal finishing.

Stops Rust & Chemical Damage
Zinc plating on steel parts creates a barrier against corrosion.
Reduces Wear & Tear
Hard chrome plating cuts friction, making components last longer.
Looks Matter Too
Gold finishes for jewelry / Chrome for car trim – it’s about aesthetics.
Keeps Current Flowing
We plate copper onto circuit boards because it conducts electricity best.
Better Solder Joints
Tin plating helps electronics components bond properly during assembly.
Fix Worn-Out Parts
Rebuild engine crankshafts or bearings by adding new plating material.
Specialized Solutions
Aerospace needs nickel plating: handles extreme heat.
Medical implants use biocompatible coatings so bodies don’t reject them.
Copper Plating
Primarily for base layers – boosts corrosion resistance and helps subsequent coatings stick better.
Watch for: Oxidation (forms non-conductive patina). Always needs a topcoat.
Nickel Plating
Works as a base layer or decorative finish. Fights corrosion/wear – electroless nickel rivals chrome durability.
Heads-up: Magnetic nature messes with electronics (e.g., DIN connectors). Avoid in signal-critical areas.
Gold Plating
King of contact surfaces: Optimizes conductivity and signal clarity.
Stable performance; High cost
Palladium-Nickel Plating
Outperforms gold: Better signal transmission + extreme wear resistance.
Why it wins: Palladium’s anti-corrosion + nickel’s hardness.
Tin-Lead Plating
Was the solderability champ, now phased out (lead regulations).
Switched to: Bright/matte tin alternatives.
Silver Plating
Unbeatable conductivity/signal quality – still works when oxidized.
Downsides: Tarnishes without maintenance; premium pricing.
› Cathode
The object to be plated (e.g., connector terminals or metal surfaces) where metal ions deposit into a solid coating.
› Electroplating Anodes Explained
Soluble Anodes
• Material: Matching plating metal (e.g., copper anodes for copper baths)
• Function: Dissolves to maintain metal ion concentration
• Key use: Standard plating operations
Insoluble Anodes
• Material: Non-consumable substrates (e.g., titanium/iridium oxide)
• Function: Facilitates electron transfer without dissolution
• Key use: Precious metal plating (white gold, etc.)
› Plating Solution
Contains ions of the target metal. Composition and concentration determine coating thickness, adhesion, and appearance.
› Plating Tank
Material Requirements:
• Must handle corrosive environments and thermal cycling
• Typical choices: polypropylene or 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 sin
Water Cooling：Built-in water circulation line
