The High Speed Metal Slitting Line is an integrated coil processing system designed to slit, cut, separate, and rewind metal coils with high accuracy and stable performance. It is suitable for processing carbon steel, galvanized steel (GI), and pre-painted galvanized steel (PPGI) in applications where manufacturers need consistent strip widths, clean cuts, and efficient coil handling.
This steel coil slitting machine combines an electric decoiler, feeding and leveling section, precision slitting and cutting unit, scrap winder, damping system, hydraulic recoiler, hydraulic station, and PLC control system. Therefore, operators can complete multiple coil processing operations through one coordinated production line.
With a maximum material width of 1250 mm and a processing thickness of 0.3–0.8 mm, the line provides a practical solution for light and medium-duty coil processing. In addition, the system can operate in a dedicated cut-to-length mode, allowing users to produce flat sheets without activating the slitting and recoiling functions.
High-Performance Coil Slitting and Processing
The production line starts with a 6-ton electric decoiler, which securely supports the incoming steel coil and feeds the material into the processing section. The decoiler uses automatic motor transmission and a mechanical press arm to help prevent coil deformation during operation.
Next, the leveling section removes unwanted coil curvature before the material enters the slitting and cutting unit. The machine uses heat-treated leveling rollers and precision shafts to maintain stable material guidance throughout the process.
The slitting section uses 12 pairs of slitting blades, while the cross-cutting system uses hydraulic power. As a result, the operator can divide the parent coil into multiple narrow strips or cut the material into predetermined sheet lengths.
Moreover, the main slitting shaft can be disengaged when the customer only needs cross-cutting. This feature makes the line more flexible because users do not need to run the complete slitting and recoiling process for every production order.

Precision Slitting, Leveling and Scrap Handling
The metal coil slitting machine uses a welded 350H steel frame and solid 45# steel shafts. After heat treatment and hard chrome coating, the shafts provide improved surface durability and stable operation during continuous processing.
The leveling unit contains 8 upper rollers and 9 lower rollers. These rollers help straighten the incoming strip before it reaches the cutting area. Consequently, the machine can maintain more consistent strip tracking and improve the quality of the finished coils.
The slitting blades use Cr12MoV steel, while the blade assembly includes 12 pairs of knives secured with bolts and screws. Operators can configure the cutting arrangement according to the required strip widths.
After slitting, the scrap winder collects the narrow edge strips. Two 2 kW torque motors drive the winding system, while the guiding mechanism keeps the scrap strips organized. The system is particularly suitable for edge scrap with widths of 20 mm or less.
This arrangement reduces loose scrap around the production area and helps operators maintain a cleaner working environment.
Hydraulic Recoiler and Tension Control
After the material passes through the slitting and damping sections, the finished strips enter the 6-ton hydraulic recoiler. The recoiler winds the separated strips into compact coils while maintaining adjustable winding tension.
A hydraulic loading car supports coil removal and handling after production. Its V-shaped lifting platform and hydraulic movement system make it easier to transfer finished coils from the recoiler.
Meanwhile, the damping device separates the slit strips and creates appropriate back tension. This becomes especially important when processing thin metal because insufficient tension can cause loose or uneven winding.
The damping section incorporates a pre-separation shaft, arch structure, pressure shaft, pneumatic damping mechanism, and felt pads. Operators can manually adjust the tension according to the material and production requirements.
As a result, the coil slitting line can achieve more orderly rewinding and reduce problems such as loose edges, uneven strip separation, and poor coil formation.
PLC Automation and Flexible Production Modes
The control system uses a Delta PLC, inverter, and touchscreen panel to coordinate the main production functions. Operators can set the cutting length, production quantity, and operating parameters directly from the control interface.
The system provides automatic length measurement and quantity counting. In addition, the operator can correct length deviations through the control interface, which makes parameter adjustment more convenient during production.
Another useful feature is the independent Cut-to-Length Only Mode. When the customer needs flat sheets instead of slit coils, the slitting and recoiling functions can be switched off. The main slitting shaft can also be lifted away from the material path.
Therefore, one production line can handle different processing requirements instead of relying on separate machines for every application.
The system also includes a foot pedal with a long cable for convenient start/pause operation. Furthermore, the entry guide incorporates vertical side rollers to improve material alignment before the strip reaches the leveling and slitting section.

Metal Cut To Length Line
The Metal Cut To Length Line provides an efficient solution for transforming metal coils into flat sheets with precise and repeatable lengths. During operation, the coil passes through the decoiler, feeding and leveling section before entering the hydraulic cutting unit. The PLC control system allows operators to set the required cutting length and production quantity, while the leveling rollers help maintain a flat and stable sheet surface. Therefore, the steel coil cut to length line is well suited for manufacturers that need accurate sheet dimensions for roofing, construction, fabrication, and downstream metal processing.
Combined Slitting and Cut To Length Line
A Combined Slitting and Cut To Length Line offers greater flexibility by integrating longitudinal slitting and transverse cutting functions into a single production system. Depending on the production requirement, operators can slit a wide coil into several narrow strips, cut the material into fixed-length sheets, or switch between different processing modes through the PLC control system. This multifunctional configuration reduces the need for separate machines and makes better use of factory space. As a result, the Metal Slitting and Cut To Length Line can provide a practical solution for customers who handle different coil widths, strip sizes, and sheet-length requirements.
