It can significantly improve labor productivity and production efficiency. The line can also be equipped with a complete range of water treatment and drying equipment according to the production process.

Main Configuration

PLC: Mitsubishi Electric, Japan
Inverter: Mitsubishi Electric, Japan
Touch Screen: Kunlun Tongtai
Proximity & Photoelectric Sensors: Omron, Japan
Contactors & Thermal Relays: High-quality industrial electrical components
Traveling Cable: Dongguan Jinxing advanced 40-core flat cable
Control Cabinet: Professionally designed with a compact and corrosion-resistant structure. The internal wiring is organized and clearly numbered, while all electrical components and operating functions are labeled in English for easy operation and maintenance.

Control System

Automatic & Manual Operation
The system supports both automatic and manual control. Under normal operation, parameters such as workpiece processing time, transfer speed, and lifting speed are automatically controlled according to the preset program. Individual transporter movements, including start, stop, lifting, lowering, and travel, can also be operated manually when required. This allows maintenance or troubleshooting to be carried out efficiently while minimizing production downtime.
Program Memory & Power Recovery
The control system features program interruption, power-off memory, and recovery functions to help handle unexpected situations and resume operation efficiently.
Emergency Protection
Multiple emergency-stop devices are installed throughout the system to provide comprehensive safety protection during operation and maintenance.
Flexible Process Programming
The process sequence can be easily modified according to different products and plating requirements, providing greater flexibility for multi-product production.

Typical Passivation Process

The exact process sequence can be customized according to the workpiece material, plating type and required surface treatment performance. A typical automated passivation process may include:
Loading → Water Rinsing → Passivation Treatment → Water Rinsing → Neutralization or Post-Treatment → Final Rinsing → Drying → Unloading
The single-arm transfer system moves the workpieces between individual tanks according to the preset PLC program. Process parameters such as transfer position, immersion time and lifting speed can be adjusted according to the production requirements.

Quality Control

Each passivation line is inspected during assembly and commissioning before shipment. Key control points include transfer movement, positioning accuracy, tank configuration, electrical wiring, PLC program operation, safety functions and emergency-stop response.
The control system is tested under simulated operating conditions to verify the programmed process sequence and communication between sensors, transfer equipment and control components. Final inspection is completed before delivery to ensure that the equipment meets the agreed technical specifications.
