2500A ±12V Hard Chrome Plating Rectifier

Lyhaina — Mon, 30 Jun 2025 06:18:08 +0000

» Product Description

In a 2500a ±12v hard chrome plating rectifier, 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.

» Product Applications

Manufacturers widely use electroplating rectifier equipment for various surface treatment applications, including PCB electroplating, hard chrome coating, copper plating, nickel plating, zinc plating, gold plating, tin plating, and silver plating, among other metal finishing.

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).

» Types of electroplating

› 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.

» Elements of Electroplating

› 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.

150A 15V Electroplating Rectifier Power Supply

Lyhaina — Wed, 07 May 2025 02:35:31 +0000

» Product Description

In an Electroplating 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.

– Used in medical devices (e.g., biocompatible coatings).

» Types of electroplating

› 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.

» Elements of Electroplating

› 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.

4×200A 6V Electroplating Rectifier Power Supply

Lyhaina — Sat, 26 Apr 2025 05:53:12 +0000

» Product Description

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 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.

» Product Applications

Plating rectifiers support surface treatments like PCB electroplating, hard chrome coating, and metal plating (Cu, Ni, Zn, Au, Ag).

25V 1500A Hard Anodizing Rectifier Power Supply

Lyhaina — Tue, 22 Apr 2025 02:15:37 +0000

» Product Description

The Anodizing Rectifier delivers precise high-voltage control (up to 120V+) for hard anodizing. It supports currents from hundreds to tens of thousands of amps. Unlike decorative processes at 20V–24V, its high-frequency switching slashes oxide layer formation time by 30% and energy use. Compact design ensures stable current, enabling uniform Al₂O₃ films for corrosion-resistant, ultra-hard surfaces. Post-treatments like hot-water sealing integrate smoothly, boosting durability and color uniformity in dyed parts. With ±1% voltage stability, it produces repeatable aerospace and architectural components while reducing physical footprint and downtime.

» Product Applications

Anodizing Rectifier drives the electrochemical formation of aluminum’s oxide layer (Al₂O₃), critical for industrial applications demanding corrosion resistance and structural integrity. By delivering stable current outputs, it enables uniform growth of protective coatings with adjustable thickness (5–25μm), essential for automotive trim exposed to road salts or marine-grade architectural window frames. The technology ensures surfaces achieve 500–900 HV hardness for scratch-resistant smartphone casings while maintaining dielectric properties for heat sink insulation in 5G equipment. Post-anodizing, the rectifier-compatible sealing process locks in organic dyes for fade-resistant facade panels and medical device markings. Its adaptive voltage control (12–120V DC) supports both Type II decorative finishes on consumer electronics and Type III hard coatings for aircraft landing gear components, achieving 60% faster cycle times versus traditional rectifiers through pulsed current optimization.
