Industrial Automatic Gantry Zinc Plating Line Zinc Electroplating Equipment
Automatic Gantry Zinc Plating Line
This automatic gantry zinc plating line is designed for automated zinc electroplating of metal components requiring corrosion protection and a uniform zinc coating.
The system uses an automatic gantry transfer mechanism to move workpieces between cleaning, rinsing, zinc plating, post-treatment and drying processes according to a programmed sequence. Loading and unloading can be performed manually, while the main plating process is automatically controlled.
The line can be customized according to workpiece dimensions, weight, production volume, required zinc coating thickness, process sequence and available factory space. Supporting systems such as rectifiers, heating, filtration, circulation, ventilation and exhaust treatment can be integrated according to the project requirements.
Typical Zinc Electroplating Process
The exact process sequence depends on the workpiece material, surface condition and required coating performance. A typical zinc electroplating process may include:
- Loading
- Degreasing / Cleaning
- Water Rinsing
- Acid Pickling / Activation
- Water Rinsing
- Zinc Electroplating
- Water Rinsing
- Passivation
- Sealing, if required
- Final Rinsing
- Drying
- Inspection and Unloading
The actual process stages, treatment time, bath temperature, current and zinc coating thickness should be determined according to the workpiece material and customer's coating requirements.

Project Case - Automatic Zinc Plating Line
Application: Zinc Electroplating for Metal Components
Automation: Automatic Gantry Transfer
Loading / Unloading: Manual
Control: PLC-Based Automatic Control
Project Scope: Design, Manufacturing, Installation and Commissioning
The zinc plating line was designed according to the customer's workpiece dimensions, production volume and required corrosion protection performance.
The automatic gantry transporter transfers the workpieces between the cleaning, rinsing, zinc plating and post-treatment stages according to the programmed process sequence.
The complete system can be integrated with rectifiers, filtration, heating, drying, ventilation and exhaust treatment according to the project requirements.
Main Configuration
Automatic Gantry Transfer System
The gantry transporter performs horizontal travel and vertical lifting to move flight bars between process tanks. High- and low-speed movement can be configured according to the production process.
PLC / Automatic Control
The control system manages the programmed transfer sequence and processing time, reducing manual intervention during the main plating process.
Zinc Plating Tanks
Tank dimensions and materials are selected according to the chemical process, workpiece dimensions and production requirements.
Rectifier System
The rectifier provides controlled DC power for the zinc electroplating process. Its capacity is selected according to the required plating area and process parameters.
Filtration and Circulation
Filtration and circulation systems can be configured to help maintain plating bath cleanliness and stability during production.
Rinsing System
Multiple rinsing stages can be incorporated between chemical processes to reduce cross-contamination and support process consistency.
Drying System
A drying system can be integrated after the final treatment process according to the workpiece and production requirements.
Exhaust Treatment
Ventilation and exhaust treatment can be integrated to manage process fumes and support the overall environmental control system.

Frequently Asked Questions
Is this a zinc electroplating line or hot-dip galvanizing line?
This equipment is designed for zinc electroplating processes rather than hot-dip galvanizing. The exact process configuration depends on the workpiece and required zinc coating.
Can the zinc plating line be fully automatic?
Yes. The main transfer and plating process can be automated using a gantry transporter and PLC-based control system. Loading and unloading can remain manual if required.
What products can be zinc plated?
The line can be configured for suitable metal components, hardware and industrial parts. The final configuration depends on product dimensions, material, weight and production requirements.
Can the plating line be customized?
Yes. Tank dimensions, process stages, gantry capacity, rectifier, filtration, drying, exhaust treatment and automation level can be customized.
What information is required for quotation?
Customers should provide product drawings or photos, material, dimensions, weight, production quantity, required zinc coating thickness and available factory space.
