Robotic Zinc Cathode Stripping System for Zinc Electrowinning Tankhouses
Zinc stripping is a critical downstream step in zinc electrowinning production. Traditional manual stripping operations face rising labor costs, unstable output, high safety risks and high product damage rates, which have become major bottlenecks restricting tankhouse efficiency and intelligent upgrading.
Our automatic and robotic zinc stripping systems are purpose-built for zinc electrowinning workshops. They replace heavy manual work with mechanized and intelligent stripping, significantly improving production efficiency, reducing zinc sheet damage rate, lowering labor cost and eliminating safety hazards in acid mist environments.

Industry Challenges: Pain Points of Traditional Manual Zinc Stripping
Manual zinc stripping has long been a high-cost, high-risk and low-efficiency link in zinc hydrometallurgy plants:
- High labor cost: A single production line requires 8–10 operators working in shifts, with labor accounting for over 40% of stripping section costs.
- Unstable & low efficiency: Manual output is ≤120 plates per hour per person, and performance fluctuates obviously due to fatigue and shift changes.
- High safety risks: Operators work long-term in metal splashing and acid mist environments, with an injury rate of around 0.7%.
- High zinc sheet damage rate: Manual operation errors lead to a finished product yield of ≤95%, causing direct metal loss.
- Harsh working environment: High labor turnover makes recruitment and retention increasingly difficult.
Driven by national intelligent manufacturing policies in the nonferrous metals industry and enterprises' demand for cost reduction, efficiency improvement and ESG upgrading, intelligent stripping transformation has become an inevitable trend for zinc smelters.

Core Advantage
1. Ultra-high stripping yield
- Opening rate ≥ 98%, greatly reducing the rate of un-stripped plates and secondary manual rework.
- Mechanical uniform force stripping avoids artificial tearing damage, significantly improves the yield of finished zinc sheets, and reduces direct metal loss.
2. High & stable production efficiency
- Rated stripping speed ≥500 plates per hour, 4–5 times the efficiency of manual stripping per unit time.
- Continuous and stable operation 24/7, free from fatigue and shift factors, ensuring stable output of the tankhouse.
3. Greatly reduce labor cost
Only 5 personnel are required for the whole line: 2 for loading/unloading, 1 for inspection station, 1 for equipment operation, 1 for zinc sheet stacking. Compared with 8–10 people in the traditional manual line, the labor demand is reduced by nearly 50%.
4. Low maintenance & operating cost
- Few consumable parts, low wear of the stripping knife, and low long-term maintenance cost.
- The whole machine has a sturdy structure and long service life, suitable for long-term continuous operation in smelting plant environments.
5. Improve workplace safety & ESG performance
- Workers no longer need to stay in the acid mist and high-risk stripping position for a long time, which greatly reduces occupational injury risks.
- It helps enterprises reduce high-risk positions, improve working environment, and meet ESG and intelligent manufacturing assessment requirements.
