1. Process flow
1. Pre-treatment stage
Degreasing and oil removal → pickling and activation → water
washing → surface conditioning to ensure the surface of the
substrate is clean and activated.
2. Electroplating stage
Hanger loading: The workpiece is fixed to the hanger by a
self-locking chuck, and is moved into the electroplating tank by
the crane according to the preset path.
Electroplating execution: The current density and time are set according to the plating type (such as zinc plating, chrome plating), and the metal deposition is completed after the electrode is energized.
3. Post-treatment stage
Water washing → passivation → drying → quality inspection to remove
residual plating solution and enhance anti-corrosion performance.
2. Technical parameters
Operation speed: Crane moving speed 0.5-5m/min (adjustable).
Current range: Maximum current of single station 2000A (supports water cooling).
Applicable plating types: zinc plating, nickel plating, chrome plating, alloy electroplating, etc.
Productivity: 30-200 pieces per hour (depending on the size of the workpiece and the complexity of the process).
3. Technical advantages
Efficient and stable: Automated continuous operation, more than 300% efficiency improvement over manual lines.
Uniform coating: Dot matrix electrode + precise current control, thickness deviation ≤5%.
Energy saving and environmental protection: Closed tank + circulation filtration system to reduce plating solution loss and exhaust gas emissions.
Safe and reliable: Multiple protections (anti-collision, leakage monitoring, emergency stop) ensure safe operation.
4. Applicable scenarios
Industry: automotive parts, bathroom hardware, electronic connectors, furniture decorations, etc.
Workpiece type: Suitable for large-size, special-shaped parts and high-precision metal parts plating.
1. Core structure system
1. Driving system
Gantry crane: Gear rack drive and rotary encoder auxiliary positioning are used to ensure the precise movement of the hanger between the electroplating tanks, with a positioning accuracy of ≤1mm.
Anti-collision protection device: Infrared sensing or mechanical limiter is configured to prevent collision accidents during driving.
2. Plating tank group
Multi-tank layout: Degreasing tank, pickling tank, electroplating tank, washing tank, etc. are configured according to the process flow, and the tank body is made of corrosion-resistant PP or 316L stainless steel.
Electrode system: Dot matrix cathode/anode arrangement is adopted to optimize current distribution and reduce tank voltage, thereby improving the uniformity of plating.
3. Lifting system
Self-locking hanger: The workpiece is quickly fixed through a spring chuck or a magnetic clamp, supporting the stable lifting of special-shaped parts (such as hardware and auto parts).
Rotation mechanism (optional): The drive hanger rotates 360° to
ensure that the plating solution covers the inner cavity and
complex surface of the workpiece.
4. Conveying system
Linear track: laid along the arrangement direction of the
electroplating tank, the crane realizes the sequential transfer of
the workpiece through the track.
S-shaped track (special design): the gear and the sawtooth mesh
drive the hanger to realize the curved movement of the workpiece in
the electroplating tank, extending the effective electroplating
time.
2. Key functional components
1. Conductive system
Conductive rod and copper busbar: the anode/cathode conductive
rod is made of pure copper, and the busbar is configured outside
the tank to match the high current demand (maximum 2000A for a
single station).
Water cooling device: designed for high current stations to
prevent overheating of conductive parts.
2. Control system
PLC and HMI: set the electroplating parameters (time,
temperature, current density, etc.) through the touch screen,
support programmed control and fault self-diagnosis.
Sensor module: integrated displacement sensor, temperature
sensor, etc., real-time monitoring of equipment operation status
and feedback to the control center.
3. Auxiliary equipment
Circulation filtration system: equipped with magnetic pump and
5μm precision filter to reduce impurities in the plating solution
and extend the service life of the plating solution.
Temperature control system: steam heating or electric heating
tube, combined with PID algorithm to achieve precise control of the
tank temperature (±2℃).
3. Technical parameters
Operation speed: driving speed 0.5-5m/min (programmable
adjustment).
Applicable plating type: support zinc plating, nickel plating,
chrome plating and alloy electroplating processes.
Productivity range: 30-200 pieces per hour (depending on the
workpiece size and coating thickness requirements).
4. Design features
Modular layout: support station expansion and process adjustment,
to meet the production needs of multiple varieties.
Enclosed structure: reduce plating solution volatilization and
exhaust gas emission, in line with environmental protection
requirements.
Safety redundancy design: integrated leakage protection,
emergency stop button and multiple mechanical limit to ensure safe
operation.
