Automatic Anodizing and Electrophoretic Coating Line with 0-15 μm Film Thickness and Automated Process Control for Outdoor Applications

This automatic surface treatment production line is specifically designed for aluminum clothes drying racks, drying rods and related aluminum components. The system integrates multiple processes including sulfuric acid anodizing, electrolytic coloring or dyeing, medium-temperature sealing, and electrophoretic coating to meet various product requirements.

The actual process sequence can be adjusted according to aluminum alloy, required color, film thickness, coating system and application environment.

Final equipment configuration is determined according to drying rack dimensions, rod length, aluminum alloy, loading method, batch weight, process cycle and production requirements.

The line is designed for aluminum clothes drying racks, drying rods and related aluminum components. The hanger system and tank dimensions can be customized according to workpiece length, weight and geometry.

Yes. The line can be configured for natural aluminum finishes or colored surfaces. Electrolytic coloring or dyeing can be selected according to the required color and surface appearance.

Clothes drying racks and drying rods may be exposed to sunlight, humidity and outdoor environmental conditions. Electrophoretic coating adds a separate coating layer to the anodized surface and can be selected when additional surface protection and color retention are required. Actual outdoor performance depends on coating type, thickness, UV exposure, humidity and other service conditions.

No surface coating should be described as completely preventing fading. Electrophoretic coating can be selected to improve resistance to environmental exposure, but actual color retention depends on the coating formulation, film thickness, UV exposure and test conditions.

The specified anodizing film thickness range is 0-15 μm. The actual thickness is determined according to the aluminum alloy, workpiece geometry and required surface treatment.

Medium-temperature sealing is used after anodizing and coloring to treat the anodized film before the subsequent coating process. The sealing parameters are selected according to the film thickness and overall surface treatment system.

Yes. The proposed system uses an automatic transfer and process control system. The actual automation level can be configured according to the customer's production requirements and operating method.

Production capacity is customized according to customer requirements. It is calculated based on workpiece dimensions, weight, batch loading, process cycle, working hours and target output.
