High Stability Power for Anodizing & Micro-Arc Oxidation Process

Introduction to Anodizing Rectifier

Anodizing Rectifier is a high-stability industrial device for metal oxidation treatment. Firstly, it provides accurate DC and pulse output for standard anodizing, hard anodizing and micro-arc oxidation. In addition, it creates uniform, high-hardness oxide films for aluminum, magnesium and titanium alloys. Furthermore, it adapts to both laboratory research and large-scale industrial production lines for consistent finishing quality.

Compared with ordinary industrial equipment, the GAOHUI Anodizing Rectifier adopts advanced IGBT PWM technology. Specifically, it supports full parameter customization for different alloy materials and process standards. As a result, it effectively reduces surface defects and improves finished product stability for long-term batch production.

Core Functions of Anodizing Rectifier in Oxidation Treatment

Anodizing Rectifier serves as the core power control unit for oxidation processes. Therefore, its stability and precision directly determine coating quality and production efficiency. In particular, every functional design targets modern industrial surface treatment requirements for higher qualification rates.

The Anodizing Rectifier supports DC, single pulse and dual pulse output modes. For this reason, it flexibly matches decorative anodizing, hard anodizing and micro-arc oxidation scenarios. Meanwhile, users can store multiple process recipes for quick mode switching during production.

It features adjustable frequency and duty cycle for ultra-fine power tuning. As such, the equipment maintains stable current and voltage output. In turn, it guarantees uniform oxide film thickness and smooth surface texture for all metal workpieces.

Equipped with multi-dimensional safety protection, the Anodizing Rectifier prevents overcurrent, overvoltage and overheating faults. Consequently, it avoids unexpected shutdowns and workpiece damage. Ultimately, these reliable protections extend the equipment’s overall service life.
