Gantry Type Rack Plating Line Automatic Zinc Plating Equipment For Metal Parts

This automatic gantry zinc plating line is designed for rack-mounted metal parts that require consistent zinc coating and automated process handling. The system combines an automatic gantry transporter with PLC and IPC-based process control.

Loading and unloading can be performed manually, while the transfer between process stations is automatically controlled according to the selected production recipe. Operators can enter the product code before production, and the IPC retrieves the corresponding process data and sends the programmed sequence to the PLC.

The gantry transporter then performs the programmed lifting, horizontal travel and positioning operations to move each flight bar through the required process stations. Process information such as temperature, processing time and current can be transferred to the IPC for monitoring, record keeping and production traceability.

1. Loading - The operator moves the trolley carrying the flight bar, jig, and workpieces to the loading station.
2. Product Identification - The product code is entered through barcode scanning, an IC card, or the computer interface. After pressing "Load Ready," the system identifies the required process recipe.
3. Automatic Transfer - The IPC sends the process instructions to the PLC. The gantry transporter automatically picks up the flight bar from the trolley and transfers it to each processing station according to the programmed sequence.
4. Automatic Plating - Each process is carried out according to the preset recipe, with parameters such as processing time, temperature, current, and other operating conditions automatically controlled.
5. Unloading - Once the plating cycle is complete, the flight bar is returned to the trolley at the unloading station. An audible alarm notifies the operator that the products are ready for unloading.
6. Data Recording - Key process information is continuously collected and stored in the IPC. Operators can review, save, and print production records for process monitoring, quality control, and traceability.

• Fully Automatic Process: Loading and unloading are manual, while all plating processes are completed automatically according to preset programs.
• Gantry Transfer System: Multiple gantry transporters can be configured according to production needs. They provide vertical lifting and horizontal movement with high- and low-speed operation.
• Easy Operation: Operators simply enter the product code by barcode, IC card, or computer. The IPC automatically retrieves the corresponding process recipe and sends instructions to the PLC.
• Precise Positioning: Absolute positioning technology and unique tank identification ensure accurate and reliable transporter movement.
• Multiple Safety Systems: Collision avoidance, travel limit protection, derailment prevention, and emergency braking systems ensure safe equipment operation.
• Process Data Recording: Key parameters such as temperature, processing time, and current are automatically monitored and stored in the IPC for review, printing, and process traceability.

Automatic gantry zinc plating lines can be configured for a wide range of rack-mounted metal components, including:

• Automotive metal components
• Fasteners and hardware
• Stamped metal parts
• Machinery components
• Electrical and electronic hardware
• Precision metal components
• General industrial metal parts

The final plating process and line configuration should be determined according to the substrate material, workpiece geometry, required coating specification, production volume and factory layout.

The gantry transporter is responsible for moving flight bars between the loading area and the individual process stations. The system supports:

• Vertical lifting and lowering
• Horizontal travel
• High-speed and low-speed movement
• Automatic positioning
• Programmed process sequencing
• Flight-bar transfer between process tanks

The number of gantry transporters can be configured according to the required production efficiency and line layout. For higher production requirements, multiple transporters can be integrated into the line design.
