PLC Controlled Automatic Gantry Anodizing Line For Aluminum Mobile Phone Housings

The anodizing line uses an automatic gantry transfer system to move flight bars between the loading station, process tanks and unloading station.

The gantry transporter provides:

• Vertical lifting and lowering
• Horizontal travel
• High- and low-speed movement
• Automatic positioning
• Programmed process sequencing

The transfer system is controlled according to the selected product recipe, allowing different aluminum housing models to run with their corresponding process parameters.

Operators can select the required product code before production. The IPC retrieves the corresponding process recipe and sends the programmed sequence to the PLC.

The system controls the movement of the gantry transporter according to the predefined process sequence.

Key process information, including temperature, processing time and electrical parameters, can be recorded by the control system for production monitoring and traceability.

The gantry system incorporates multiple safety protection functions, including:

• Collision avoidance
• Rail end protection
• Anti-drop protection
• Emergency braking
• Emergency stop functions

These systems are designed to reduce operational risks during automatic material transfer.

This automatic anodizing line is designed for surface treatment of aluminum components where consistent anodizing, coloring and process control are required.

Typical applications include:

• Aluminum mobile phone housings
• Aluminum electronic device housings
• Precision aluminum components
• Consumer electronics parts
• Other customized aluminum components

The actual process sequence can be configured according to the material, part geometry, required surface finish and production requirements.

Application: Aluminum mobile phone housing anodizing

Equipment: Automatic gantry-type anodizing production line

Workpiece: Aluminum mobile phone housings

Loading & Unloading: Manual loading and unloading with trolley-based flight bar transfer

Automation: Automatic gantry transfer system

Control System: PLC + IPC process control

Process Management: Preset process recipes based on product codes

Process Monitoring: Temperature, processing time and current data are recorded for production tracking

Safety System: Collision avoidance, rail anti-drop protection and emergency braking system

Customization: Tank layout, transfer system, process configuration and production capacity can be customized according to the customer's requirements.

The line is designed for automated handling of aluminum housings through multiple anodizing and auxiliary processes. Operators only need to load the workpieces, select or enter the corresponding product code, and unload the processed parts after completion. The control system manages the programmed process sequence and records key process parameters during production.
