Alkaline Zinc-Nickel Barrel Plating Equipment
Barrel Alkaline Zinc-Nickel Plating Equipment (JYC-Ni-Barrel-Alkaline-Series)
Built for Small Parts That Need Ultra-High Corrosion Resistance
Small automotive fasteners and electronic connector housings. These parts need over 500 hours of salt spray life. Our Barrel Alkaline Zinc-Nickel Plating Equipment solves this problem. It achieves zinc-nickel co-deposition in an alkaline non-cyanide system. Nickel content is controlled at 12% to 15%. We optimized barrel conductivity and agitation. This solves the industry problem of low or uneven nickel content on barrel-plated parts. Neutral salt spray tests reach 600 to 800 hours. This meets the strict chassis and interior standards of GM, Ford, and VW.
Materials and Construction for Uniform Deposition
We use fully immersed V-shaped polypropylene barrels. These come with large cross-section cathode copper bars and multi-point contact conductive systems. Every small part gets sufficient current density. To overcome slow solution exchange inside the barrel, we add internal circulation spray systems and forced pump agitation. The solution composition stays uniform. Nickel content deviation is controlled within ±1.0%.
Three Core Advantages
First, composition is monitored dynamically.
An online XRF analyzer monitors zinc, nickel ion, and additive ratios in real time. It triggers dosing pumps automatically. Nickel ion concentration stays stable at 5 to 7 g/L.
Second, the design is low-hydrogen embrittlement.
The bath is specially optimized. Internal stress is under 40 MPa. This is suitable for high-strength small parts with hardness over HV 350. No hydrogen-induced delayed fracture concerns.
Third, automatic loading and unloading is available.
We include automatic feeders, high-speed centrifugal dewatering machines, and automatic discharge hoppers. Manual labor is greatly reduced. Parts do not get bumped or damaged.
What Buyers Often Ask
Buyers ask us: "Can high-strength small parts be produced stably?" Yes. Barrel load is 30 to 80 kg. Hoist lifting capacity exceeds 200 kg. The rectifier provides forward and reverse pulse waveforms. This optimizes coating density. The equipment meets ISO 14001. We provide complete zero-discharge or reduced-discharge wastewater solutions. Nickel-containing wastewater is collected separately. It is treated with MVR evaporators. We have proven delivery cases for both small lab barrel machines and large fully automatic barrel lines.
