A ceramic anodizing machine is specialized equipment designed to produce ceramic-like oxide films on aluminum and aluminum alloy surfaces through a specialized electrolytic process. The core principle involves using the workpiece as the anode in a composite electrolyte solution (e.g., boric acid–sulfuric acid system), with precise control of voltage, current, and temperature, promoting the formation of an oxide layer that combines ceramic hardness with metallic toughness. The resulting film typically measures 10–50 μm in thickness. It is widely used in electronics, home appliances, automotive interiors, and precision instruments, suitable for products such as smartphone cases, laptop bodies, and automotive center panels that demand high surface hardness, scratch resistance, and aesthetic quality.
Core Components of a Ceramic Anodizing Machine：
Electrolytic System – The central unit, including:
Corrosion-resistant plating tanks (PP or PVDF), compatible with composite electrolytes,Specialized electrode assemblies, with the workpiece as the anode and titanium alloy cathodes to minimize electrode contamination, and High-precision adjustable DC power supply (20–40 V, current density 1–3 A/dm²) to ensure uniform film deposition.
Electrolyte Regulation System – Maintains temperature (20–30°C) and electrolyte composition through thermostatic control and concentration monitoring, ensuring consistent film performance.
Surface Treatment System – Includes pre-treatment (fine degreasing and polishing to improve substrate flatness) and post-treatment (sealing or coating to enhance stain resistance), optimizing both appearance and durability of the oxide layer.
Control System – Operated via PLC and touchscreen, enabling real-time monitoring of electrolyte parameters and supporting preset oxide film performance to meet various product requirements.
Key Advantages
Oxide film hardness reaches HV500–800, offering superior scratch resistance compared with standard anodizing, while providing a smooth, aesthetically appealing surface.
Excellent insulating properties, suitable for electronic device housings.
High weather resistance, with long-term use without yellowing or aging.
Environmentally friendly, free from heavy metal pollution.
The ceramic anodizing machine is therefore a preferred solution for surface strengthening and decoration of high-end consumer products and precision components.
