MEIAL ML-YH DC Anodizing Rectifier & ML-SZS / Single-Wave AC-DC Coloring Power, SCR Controlled ±1% Precision Air-Cooled Power Set for Aluminum Profile Surface Treatment

DC constant current/voltage output drives aluminum substrate to generate uniform dense anodic oxide film. Stable current density eliminates uneven film thickness, edge thin layers and batch chromatic aberration, the core power equipment for decorative & hard anodizing.

• Ultra-stable DC output locks consistent current density, solving the industry’s biggest difficult of inconsistent oxide film thickness on long profiles & complex castings.
• Multi-layer hardware safety interlock prevents power tripping during full-load continuous production, protecting anode beams, hangers and whole line hardware from burnout.
• All-day air-cooled integrated cabinet requires no water pipeline layout, reducing workshop pipeline construction cost and leakage risks.
• Digital data recording, automatic calculation of oxidation time & total current, support centralized production management of fully automatic lines.

Decorative sulfuric anodizing, hard wear-resistant anodizing; automatic horizontal / vertical lines, manual sampling oxidation lines, mini lab anodizing equipment.

Special two-stage output logic: first DC activation, then adjustable AC waveform deposition of metal ions inside oxide micropores to form uniform champagne, bronze, black color layers, targeting single nickel, single tin & mixed salt coloring formulas.

• Exclusive DC pre-activation + AC coloring dual mode, greatly improve color uniformity and color repeatability for large batches of architectural profiles.
• Switchable multi AC waveforms compatible with single nickel (Spanish), single tin, mixed salt mainstream coloring baths, one unit fits multiple color production demands.
• Low-loss transformer with oxygen-free copper winding reduces heat generation, stable output under long-time coloring cycle without color fading difference.
• Independent recipe memory function, one-click recall of mature tint parameters to eliminate color deviation caused by manual misoperation.

Champagne / bronze / matte black electrolytic coloring; full-auto profile production lines, medium-sized manual coloring workshops.

Complete surface treatment workflow requires matched dedicated power:

1. ML-YH DC rectifier forms uniform oxide film carrier;
2. ML-SZS / single-wave coloring power realizes consistent electrolytic tint on film pores;
3. One-stop supply of oxidation + coloring power avoids signal mismatch between different brands, stabilizes overall yield and simplifies after-sales maintenance.
