European cutting-edge technology helps! Innovate photovoltaic ribbon manufacturing technology with Plasmait

Core highlights: Redefine metal processing efficiency and environmental standards

1. Three-strong joint technology endorsement

The dual-line plasma annealing tin coating production line jointly developed by Austrian Plasmait (official website: plasmait.com)\ROCKTA and GRM deeply integrates European cutting-edge technology and localized production needs, providing a one-stop solution from raw materials to finished products.

2. Flux-free · Green smart manufacturing

• Plasma activation technology completely replaces traditional flux, eliminates chemical residues and wastewater treatment problems, and achieves metal surface treatment without oxidation, mud, and pinholes.

• Micron-level tin coating accuracy: thickness 3-40μm, covering customized alloy requirements such as Sn/Pb/SnAgC/SnBi, smooth and bright coating, corrosion resistance and welding performance leading the industry.

2. Efficient integration · intelligent production

Integrated online wire drawing/rolling and annealing processes, supporting seamless connection with front-end processes. Equipped with HMI touch screen PLC control system and computer quality database, real-time monitoring of surface quality to ensure production stability and product consistency.

3. Ultra-high-speed production capacity and flexible adaptation

• Dual-line independent operation architecture: supports 2x pay-off → 2x wire drawing/rolling → 2x plasma treatment (cleaning/activation/annealing) → 2x tin coating → 2x take-up, the equipment length is 6-15m, the width is ≤2.5m, and the area is compact.

• Extreme speed and production capacity: The maximum speed of a single line is 600m/min (the photovoltaic welding ribbon dedicated line can reach 300m/min), the maximum production capacity is 800kg/h, and it is suitable for copper/copper-clad aluminum/copper-clad steel wires, bars, narrow strips and photovoltaic welding ribbons with a width of 0.1-30mm.
