This system is designed for high productivity, capable of producing up to 50 precise strips in a single pass while maintaining clean, burr-free edges and tight dimensional tolerances. A broad thickness range of 0.2 to 9.0 mm supports smooth transitions between delicate thin-gauge metals and robust structural steel without sacrificing accuracy or efficiency. Operators can fine-tune production speeds from 0 to 300 meters per minute, allowing the line to shift seamlessly between rapid output and precision-focused processing depending on the job requirements.

At the heart of its performance is a sophisticated tension control system, which can be configured with Felt Plate, Belt Bridle, or Roll units. These options ensure stable material flow, excellent strip flatness, and minimal surface marking. By maintaining consistent tension and reducing material distortion, the system minimizes scrap, optimizes yield, and guarantees high-quality finished coils.

To maximize uptime, the GreenLine features a Double Slitter with Turnstile arrangement. This dual-slitter setup allows quick knife changes and easy width adjustments without interrupting production, significantly reducing downtime. Heavy-duty arbors, precision-ground components, and servo-driven controls further enhance reliability, ensuring smooth operation and consistent cutting performance even during continuous high-speed runs.

Energy efficiency is a defining characteristic of the GreenLine. High-efficiency motors, regenerative braking systems, and intelligent power management work together to reduce electricity consumption without compromising output. These features not only lower production costs but also support sustainability initiatives by decreasing the facility’s overall carbon footprint.

Operators will appreciate the intuitive control interface, which simplifies setup, monitoring, and maintenance. Real-time system diagnostics and predictive maintenance tools provide early warnings of potential issues, helping to avoid unplanned stoppages and extend equipment lifespan.

Whether processing lightweight aluminum for consumer electronics or heavy hot-rolled steel for industrial construction, the GreenLine Precision Slitting System offers an ideal balance of speed, versatility, and eco-friendly performance. By combining energy-saving technology, advanced tension control, and a robust slitting mechanism, it empowers manufacturers to increase throughput, improve product quality, and meet modern demands for sustainable, cost-effective coil processing.

This system is engineered for multi-material use, handling high-speed steel (HSS), cold rolled steel (CRS), hot rolled steel (HRS), stainless steel, and aluminum. Its versatility reduces the need for separate equipment, allowing businesses to adapt quickly to customer orders and produce everything from lightweight panels to heavy structural sheets on one machine.

With a coil width capacity of 2,500 mm and the ability to cut sheets up to 12,000 mm in length, the CTL line supports a wide spectrum of production requirements. Its 35-ton weight capacity makes it capable of managing large, heavy coils with ease, ensuring stability and smooth operation even during demanding production runs. This design minimizes downtime from coil changes and helps factories maintain a steady workflow.

The system accommodates a thickness range of 0.2 mm to 9.0 mm, giving it the ability to process thin-gauge materials used in electronics, appliances, or automotive parts, as well as thicker plates required for shipbuilding, construction, or industrial machinery. By covering such a broad range, the CTL line eliminates processing bottlenecks and supports manufacturers working across diverse sectors.

Efficiency is enhanced with an adjustable speed of 0–80 meters per minute. For high-volume production, operators can utilize maximum speed to achieve fast output. For precision-critical applications, the line can be slowed down to ensure accurate cutting, edge quality, and sheet flatness. This flexibility makes the system equally valuable for large-scale orders and specialized projects.

The inclusion of two shear cutting options—stop shear and rotary shear—provides further adaptability. The stop shear is designed for precise cuts in shorter lengths or thicker materials, ensuring clean results with minimal distortion. The rotary shear enables continuous high-speed cutting, ideal for long runs where throughput and consistency are priorities. With both modes available, manufacturers can select the best cutting approach for each job.

Beyond its technical strengths, the CTL line is engineered for reliability and ease of operation. A heavy-duty structure ensures long service life under industrial conditions, while automation reduces setup time and operator workload. Minimal maintenance requirements help keep the system running smoothly, ensuring higher uptime and lower overall operating costs.

Industries such as automotive, aerospace, shipbuilding, appliances, construction, and general fabrication benefit from the CTL line’s capabilities. It enables manufacturers to expand production capacity, improve efficiency, and deliver consistent quality across a wide variety of sheet products.

In summary, the Cut-to-Length Line combines robust performance, wide material compatibility, and user-friendly operation to provide a complete coil-to-sheet processing solution. It helps manufacturers streamline production, reduce waste, and achieve high-quality output—making it a valuable investment for companies aiming to stay competitive in today’s fast-moving markets.
