80-200 Tons/Month Automatic Anodizing Production Line for LED Heat Sinks with 8–12 μm Film Thickness and Silver-White or Black Finishes

This automatic anodizing production line is specifically designed for aluminum LED heat sinks and lamp cups, featuring anodizing, electrolytic coloring, medium-temperature sealing, and controlled surface properties.

The primary anodizing process utilizes sulfuric acid anodizing followed by electrolytic coloring. The specified anodizing film thickness is 8–12 μm, with silver-white or black finishes available according to product requirements.

Black anodized surfaces can be selected for LED components where both appearance and thermal-radiation characteristics are considered in the surface treatment design. The actual thermal radiation coefficient should be evaluated based on the aluminum alloy, surface condition, coating parameters, and operating conditions.

The planned production capacity is approximately 80 to 200 Tons/Month. The automatic production line can be configured according to the dimensions, geometry, weight, loading method, and batch requirements of different LED aluminum components.

For products requiring electrical insulation, the anodized film can be designed according to a withstand-voltage requirement of ≥500 V, with the final value verified under the specified testing conditions.

*The actual withstand voltage should be verified according to the aluminum alloy, film thickness, testing method, and customer specifications.

The actual process sequence can be adjusted according to the aluminum alloy, workpiece geometry, surface condition, and required finish.

The anodizing process is configured for an 8–12 μm film thickness range. Anodizing parameters can be adjusted according to the aluminum alloy, workpiece geometry, processing time, and required film thickness.

The automatic production line uses a control system to manage workpiece transfer and process sequencing. Process timing, tank operation, and transfer positions can be configured according to the production cycle.

Electrolytic coloring is carried out after sulfuric acid anodizing to produce the required surface color. The process can be configured for silver-white or black finishes according to the LED component design.

Temperature monitoring and solution filtration systems can be integrated into the anodizing and coloring sections. Their configuration is selected according to the process requirements and production conditions.

Medium-temperature sealing is arranged after anodizing and electrolytic coloring. The sealing parameters are selected according to the anodized film thickness, aluminum alloy, and required surface properties.

For LED components requiring electrical insulation, the anodizing process can be designed around a film withstand-voltage requirement of ≥500 V. Final insulation performance should be confirmed through testing under the specified conditions.

Silver-white and black anodized finishes can be selected according to the appearance and thermal requirements of the LED component. Where thermal radiation is an important design factor, the surface treatment should be evaluated together with the aluminum alloy, surface finish, film thickness, and operating conditions.

The final configuration depends on the LED heat sink or lamp cup dimensions, aluminum alloy, batch loading weight, process cycle, and monthly production target.

This automatic anodizing line is designed for aluminum LED heat sinks and lamp cups. The hanger system, tank dimensions, and loading method can be configured according to the product geometry and dimensions.

The specified anodizing film thickness is 8–12 μm. The actual film thickness is determined by the aluminum alloy, workpiece geometry, electrical parameters, processing time, and other process conditions.

Yes. The line uses electrolytic coloring after sulfuric acid anodizing. The coloring process can be configured for silver-white or black finishes according to the product requirements.

Black anodized surfaces can be selected when an LED heat sink requires a black appearance and specific thermal-radiation characteristics. The actual thermal radiation coefficient should be determined through testing under the required material and operating conditions.

The process can be designed according to an anodized film withstand-voltage requirement of ≥500 V. Actual insulation performance depends on factors such as film thickness, aluminum alloy, surface condition, and test method.

Medium-temperature sealing is used as a post-anodizing treatment after sulfuric acid anodizing and electrolytic coloring. The process parameters are selected according to the anodized film and the required product properties.

The planned production capacity is 80 to 200 Tons/Month. Actual output depends on workpiece weight, batch loading, processing cycle, working hours, and product mix.

Yes. The tank dimensions, hanger design, transfer system, power supply, cooling system, filtration system, and process sequence can be configured according to the actual LED heat sinks or lamp cups.
