1. Product Overview
The Copper Electroplating Line is a professional industrial plating system used to deposit a uniform copper coating on metal or non-metal substrates. The copper layer significantly enhances electrical conductivity, solderability, corrosion resistance, and aesthetic appearance.
It is widely applied in PCB manufacturing, electrical connectors, automotive components, fasteners, and precision hardware, making it an essential solution for modern surface treatment processes.

2. Main Components
(1) Pretreatment System
Pretreatment is critical for ensuring plating quality and includes:
Degreasing
Pickling
Surface activation
These processes effectively remove oil, contaminants, and oxide layers to improve coating adhesion.

(2) Electroplating System (Core Unit)
The electroplating system is the core of the entire production line, consisting of:
Anti-corrosion plating tanks
Copper sulfate electrolyte
High-purity copper anodes
Cathode fixtures
Adjustable DC power supply
Precise control of current density and plating time ensures uniform and stable copper deposition.

(3) Post-treatment System
After plating, the workpieces undergo:
Multi-stage rinsing
Low-temperature drying
Optional passivation treatment
This prevents oxidation and improves corrosion resistance.

(4) Automatic Conveying System
The automated conveying system ensures continuous processing of workpieces, improving productivity and reducing labor costs.

(5) Intelligent Control System
Equipped with a PLC control system and touchscreen interface, it enables real-time monitoring of:
