Steel Structure Semi Automatic Electroplating Line For Zinc Nickel And Copper Plating

This is a semi-automatic plating line with manual loading and unloading. The system combines reliable mechanical transmission with PLC-based control to provide stable movement, accurate positioning, and flexible operation.

Main Line & Transmission System

• Main Frame: A3-type steel structure with an epoxy-coated external surface for corrosion protection. The finish color can be customized.

• Structure: Fixed plates, support columns, walkways, flat wire system, and horizontal adjustment bolts.

• Transmission: Motor and reducer-driven system with dedicated mechanisms for jig lifting and horizontal movement.

• Jig Movement: High-strength, acid-resistant, and aging-resistant belts are used for vertical lifting. Horizontal and vertical movement are controlled by brake motors and positioning mechanisms.

• Speed Control: PLC and frequency converters provide low, medium, and high-speed operation, enabling smooth start/stop, reduced inertia movement, and accurate positioning.

• Safety: Emergency stop devices are installed throughout the line for rapid shutdown during abnormal conditions.

Main Electrical Configuration

• PLC: Mitsubishi

• Inverter: Mitsubishi

• Touch Screen: Kunlun

• Proximity & Photoelectric Sensors: Omron

• Contactors & Thermal Relays: Omron

• Control Cabinet: Clearly labeled English wiring and components, with a corrosion-resistant design for convenient operation and maintenance.

• Control Modes: Automatic and manual operation, including adjustable dwell time, transfer levels, and lifting speed.

• System Functions: Interrupt, power recovery, and memory functions for handling unexpected operating condition

Multi-Process Plating Capability

Different metal parts may require different coating systems depending on corrosion resistance, appearance, conductivity, wear resistance and subsequent manufacturing requirements.

The line can be engineered around the required process sequence, with individual stages arranged for the customer's specific application.

Typical process options may include:

• Zinc plating for corrosion protection

• Nickel plating for surface protection and functional finishing

• Copper plating for conductive or intermediate coating applications

• Rinsing stages between chemical processes

• Post-treatment according to the required surface finish

• Drying before inspection or subsequent processing

The final process sequence should be determined according to the substrate material, workpiece geometry, required coating and production requirements.

The final equipment configuration is developed around the workpiece, plating process, production requirements and available plant conditions.

1. Can one electroplating line be configured for zinc, nickel and copper plating?

The process configuration can be designed for different compatible plating processes according to the workpiece and required surface finish. The actual tank sequence and auxiliary systems must be confirmed during engineering.

2. Is the line fully automatic?

The published configuration supports automatic, semi-automatic and manual transporter options. The final automation level can be selected according to production requirements.

3. What controls the plating process?

The published configuration includes PLC and computer control with DMS, together with inverter and touch-screen control. Specific control functions depend on the final system configuration.

4. What is the fastest production cycle?

The published specification indicates a fastest cycle time of up to 30 seconds per rack under the corresponding operating conditions. Actual cycle time depends on the workpiece and process configuration.

5. Can the line be customized?

Yes. Tank arrangement, transporter type, heating, rectifier, filtration, cooling, exhaust treatment and control configuration can be adjusted according to the project requirements.
