Introduction of Electrolytic Polishing Rectifier

An Electrolytic Polishing Rectifier powers high-quality metal surface finishing. It converts AC to stable, precise DC power for smooth, bright metal surfaces. We specialize in fully customized units for both electrolytic and plasma electropolishing. We skip generic off-the-shelf models. Every unit matches your workpiece material, production scale and process parameters for consistent, optimal results.

Electrolytic Polishing vs Plasma Electropolishing

Electrolytic polishing and plasma electropolishing both finish metal surfaces, but they work differently. We customize rectifiers to meet each process’s unique power needs.

Traditional electrolytic polishing uses chemical electrolyte and controlled DC power. It dissolves metal surfaces to remove micro-roughness, burrs and impurities. It creates a smooth, corrosion-resistant finish ideal for stainless steel, aluminum and copper parts in hardware and sanitary ware.

Plasma electropolishing (plasma electrolytic polishing) runs at higher voltage. It generates a plasma layer around the workpiece for faster polishing and deeper burr removal. It delivers mirror-like finishes in shorter cycles, perfect for eyewear frames, jewelry and precision hardware.

The two processes need different voltage, current and ripple control. Our custom rectifiers adapt seamlessly to both, so you get the right power for your method.

Core Features of Electrolytic Polishing Rectifier

Our electrolytic polishing rectifiers use advanced IGBT/PWM high-frequency technology. They deliver ultra-stable, low-ripple DC output to boost finishing uniformity and eliminate surface defects.

We fully customize all functions. We adjust voltage, current, control modes and cooling systems for both electrolytic and plasma electropolishing.

The rectifiers support precise constant current and constant voltage modes. You can switch modes to match different polishing stages for consistent results during long runs.

We add comprehensive safety protection to every unit. This includes phase loss, overheat, overcurrent, short circuit, undervoltage and overvoltage protection. It cuts equipment failure risks and keeps your line running smoothly.
