ABS Workpiece Electroplating Production Line with Intelligent Control

Equipment Description:

I. Process flow
1. Pretreatment stage
ABS workpieces are completed in sequence:
① Ultrasonic degreasing → ② Chemical roughening → ③ Neutralization → ④ Activation → ⑤ Chemical copper/nickel plating.

2. Electroplating stage
Multi-layer metal deposition: acid copper plating (10-20μm) → semi-bright nickel (5-15μm) → decorative chrome plating (0.1-0.3μm);
Post-treatment: water washing → passivation → hot air drying, the coating thickness deviation is ≤5%.
2. Technical parameters
Operation efficiency: daily production capacity of 500-2000 pieces per line (depending on the size of the workpiece and the thickness of the coating);
Current density: 0.5-2A/dm² in the chemical plating stage, 1-5A/dm² in the electroplating stage;
Temperature control accuracy: plating solution temperature ±1℃, drying temperature 80-120℃ (PID algorithm control);
Applicable substrates: engineering plastics such as ABS, PC/ABS alloy.

3. Equipment design features
Modular layout: supports station expansion and plating type switching (such as imitation gold, matte nickel, etc.);
Low energy consumption design: adopts pulse rectifier power supply, which saves 20%-30% energy compared with traditional DC power supply;
Environmental protection integration: equipped with acid mist collection tower (purification efficiency ≥95%) and wastewater reuse system;
Intelligent control: PLC+HMI integration, supports real-time monitoring and data tracing of process parameters (time, temperature, current);
Fault self-diagnosis system, automatically generates production reports and alarm logs.

4. Applicable scenarios
Industries: automotive interior parts (door handles, signs), bathroom accessories, home appliance buttons, electronic housings, etc.;
Coating types: high-gloss chrome (decorative), matte nickel (wear-resistant), functional alloy coating (corrosion-resistant).

Main structures and components:

1. Pretreatment system
1. Ultrasonic cleaning tank is used to remove oil and impurities on the surface of ABS plastic, with a cleaning accuracy of 5μm.
2. Chemical roughening tank uses chromic acid solution to corrode the ABS surface to form a microporous structure to enhance the adhesion of the coating.
3. Activation tank catalyzes the surface through palladium salt or silver ammonia solution to generate an active metal layer, providing reaction sites for subsequent electroplating.

2. Electroplating tank system
1. Multilayer plating tank group is configured with copper plating, nickel plating and chrome plating tanks in sequence. The tank body is made of acid-resistant PP material, resistant to high temperature (≤70℃) and corrosive liquid.
2. Suspended anode titanium basket loads metal particles (such as copper balls and nickel blocks), and is equipped with a dot matrix electrode layout to ensure uniform current distribution.
3. Circulation filtration system magnetic pump with 5μm filter to maintain the cleanliness of the plating solution and reduce impurity interference.

3. Conveying and hoisting system
1. The gantry crane and the circular track can be precisely moved through PLC control (positioning error ≤ 1mm), and the beat time is adjustable (1-5 minutes/station).
2. The rotating hanger self-locking chuck or magnetic clamp fixes the workpiece and supports 360° rotation to ensure uniform coating of complex parts (such as car signs).

4. Control system
1. The PLC+HMI integrated touch screen sets the process parameters (temperature, current density, time), and monitors the pH value and ion concentration of the plating solution in real time.
2. The temperature control module PID algorithm controls the plating solution temperature (accuracy ±1℃), with electric heating pipes or steam heating.

5. Auxiliary system
1. The drainage and ventilation system classifies and discharges acid/alkali wastewater, and the purification efficiency of the acid mist collection tower is ≥95%.
2. Safety protection devices anti-collision sensors, emergency stop buttons and leakage protection to ensure stable operation of the equipment. ‌Key parameters and design features‌
