Introducing an advanced coil-slitting line engineered for today’s smart-manufacturing era, where connectivity, flexibility and precision define competitiveness. Designed to handle a wide spectrum of materials—including high-strength steels (HSS), cold-rolled steels (CRS), hot-rolled steels (HRS), stainless steels (SS) and aluminium—this system enables service centres and fabricators to stay agile. With a maximum width of 2,500 mm and coil weight up to 35 tons, this line is built for heavy duty throughput without sacrificing versatility.

The machine supports up to 50 strips from each mother coil, covering thicknesses from 0.2 mm up to 9.0 mm, and operates across speeds from stand-still up to 300 m/min. A key differentiator is its tension-unit architecture—which includes felt-plate, belt-bridle or roll-type modules—enabling optimized strip control for varying materials and gauges. The slitter head is configured as a double-slitter or turnstile type, providing rapid tooling changes, high precision knife clearance and slender strip widths while maintaining edge quality.
In line with the surge in industrial automation and the Industrial Internet of Things (IIoT) adoption in metal-processing environments, the line is furnished for real-time monitoring, data capture and seamless integration with enterprise systems. ([Rockwell Automation][1]) Sensors embedded in the tension units and slitting section provide feedback on strip behaviour (tension fluctuations, edge run‐out, coil shape), feeding into analytics dashboards and supporting predictive maintenance models. This capability allows operators to reduce downtime, optimise yield and minimise scrap—a major benefit in today’s high-mixed, low-volume production environment. ([Davalyn Corporation][2])
The broad material range—HSS, CRS, HRS, SS and aluminium—coupled with the generous width and high‐capacity coil weight, gives operators the flexibility to handle heavy coils and large mother widths for maximal yield. Whether the job involves multistrip slit widths for automotive stampers, appliance body parts or building-product roll formers, the line offers change-over ease and high throughput. Moreover, the ability to switch between tension modes (felt-plate, belt-bridle or roll) ensures delicate materials like aluminium or stainless are handled gently, preserving surface finish and edge integrity.
With industry trends shifting toward automation, sustainability and smarter operations, this slitting line positions manufacturers not just for high throughput but also for digital readiness. Investments in such equipment pay off in terms of improved first‐pass yield, reduced scrap, enhanced traceability and better responsiveness to shifting order profiles. In an industry where flexibility, precision and data-driven control matter, this system delivers a future-proof solution.
