Zinc, Copper, and Nickel Barrel Plating Equipment is specialized electroplating machinery designed for small-sized, high-volume workpieces such as screws, electronic components, and small hardware parts. The system uses a rotating drum to continuously tumble the parts, allowing zinc, copper, or nickel ions to deposit evenly across all surfaces. It offers both high efficiency and cost-effectiveness, making it widely used in electronics, hardware, and automotive component manufacturing.
Plating Type and Equipment Characteristics：
Zinc Barrel Plating Equipment focuses on corrosion protection, using acidic or alkaline zinc electrolytes under room-temperature conditions. Coating thickness ranges from 5–30 μm, ideal for small hardware parts requiring rust prevention. The drum typically rotates at 8–12 r/min to ensure even coverage.
Copper Barrel Plating Equipment emphasizes electrical conductivity, utilizing copper sulfate electrolyte at 20–30°C. The copper layer thickness ranges from 1–20 μm, suitable for electronic components. A soluble copper anode is used to replenish copper ions in the bath.
Nickel Barrel Plating Equipment highlights corrosion resistance and decorative finish, employing nickel sulfate electrolyte at 40–60°C. The nickel layer thickness ranges from 5–50 μm, ideal for wear-resistant decorative parts. The anode can be either a soluble nickel plate or an insoluble titanium mesh, depending on process requirements.
Core Equipment Configuration
The rotating drum is made of corrosion-resistant PP or PVC, perforated with 1–3 mm holes depending on part size to prevent jamming and ensure smooth tumbling.
The electrolytic system includes the corresponding metal anode and an adjustable DC power supply (0–24V) to meet different current density requirements for various coatings.
The control system, powered by a PLC interface, continuously monitors temperature, pH level, and plating time to ensure process stability and precision.
An integrated cleaning and drying module minimizes part handling and transfer loss, significantly improving production efficiency.
Key Advantages
High batch efficiency – a single drum can process several kilograms of workpieces per cycle.
Excellent coating uniformity – the continuous tumbling action eliminates unplated or uneven areas.
Versatile process adaptability – by simply changing the electrolyte and anode, the same system can switch between zinc, copper, and nickel plating, offering exceptional flexibility.
This equipment is an ideal choice for surface treatment of small metal parts, combining precision, efficiency, and versatility in modern electroplating production.
