Automatic Gantry Hard Anodizing Line for Aluminum Surface Treatment
Automatic Gantry Hard Anodizing Line for Aluminum Surface Treatment
Product Overview
The Automatic Gantry Hard Anodizing Line is designed for controlled hard anodizing of aluminum components in industrial production environments. The system integrates gantry transfer, programmable process control, dedicated hard-anodizing rectification, bath temperature control and process data recording to provide consistent treatment conditions across multiple process stages.
The line can be configured according to workpiece dimensions, production capacity, process sequence and required anodizing parameters. Automatic transfer between process tanks reduces manual handling and helps maintain repeatable processing conditions.
- This is an automatic line with manual loading and unloading, featuring flight bar transfer by trolley
- Configurable number of gantry transporters with vertical lifting and horizontal high/low speed movement functions to increase work efficiency
- Low temperature chiller maintains bath liquid at -10°C, achieving product hardness of HV200-1500, widely used in automotive and aviation fields
- Special hard anodizing rectifier with separate PLC and touch screen for segmented current and voltage loading, enabling customizable oxidation effects
Key Equipment Characteristics
- Fully automated operation except for loading and unloading
- Easy operation with product code input for automated process execution
- Reliable running with absolute positioning and unique tank barcodes to prevent orbital deviations
- Multiple safety protection systems including collision avoidance, fall prevention rubber blocks, offside outage devices, and emergency brake safety ropes
Basic Operation Instructions
First, manually push the trolley loaded with flight bar, jig and product to the loading station. Enter the product code (via barcode input, IC card input or computer input) and press the "load ready" button. The IPC will call the pre-stored technological data and transmit relevant orders to the PLC, directing the traveling crane to the loading section to lift the flight bar. The crane then conveys products sequentially to each process station according to the technological data. When the flight bar reaches the unload station, an audible reminder alerts the operator to prepare for unloading. The operator pushes away the trolley for off-line unloading and presses the "unload ready" button. Throughout the process, plating data (temperature, process time, current, etc.) is stored in the IPC for review, filing, and printing.
Engineering Design
1. Gantry Transfer System
The gantry transfer system is designed to move flight bars between individual process tanks according to the programmed process sequence. Vertical lifting and horizontal travel functions allow the system to coordinate loading, processing and unloading operations.
2. Hard Anodizing Rectifier
A dedicated rectifier supplies controlled current and voltage during the hard anodizing process. Segmented current and voltage settings can be configured according to the process requirements of different workpieces.
3. Bath Temperature Control
A low-temperature cooling system is used to control the anodizing bath temperature. Stable temperature control helps maintain consistent process conditions during hard anodizing.
4. PLC + IPC Control
The IPC stores process recipes and communicates the relevant process parameters to the PLC. The PLC then controls the movement and operation of the gantry system according to the selected process program.
5. Process Data Recording
Key process information such as temperature, processing time and current can be recorded through the IPC for production monitoring and traceability.
