KINGREAL STEEL SLITTER has long specialized in the R&D and manufacturing of cut to length lines. Leveraging mature technology, we have comprehensively upgraded the parameters and performance of standard cut to length lines and developed a specialized high speed cut to length line. This customized system achieves a maximum production speed of 80 m/min, shattering the capacity bottlenecks associated with traditional lines.
During the R&D and design phase, the optimization focused on two core modules: the shearing system and the stacking unit. Refinements to these structures ensure the line is well-suited for processing flat-rolled metal coils. By utilizing an efficient operational logic, the system seamlessly integrates coil uncoiling, shearing, and stacking. This approach maximizes processing efficiency, ensures high precision through sophisticated structural design, and enhances operational safety, enabling the standardized, large-scale transformation of metal coils into high-precision flat sheets.

●High-Speed Cutting At full operating speed, the KINGREAL STEEL SLITTER high speed cut to length line ensures uninterrupted metal strip feeding, eliminating the losses associated with start-stop operations and meeting the demands of continuous production. To achieve the 80 m/min production standard, the equipment features rotary shear or dynamic flying shear structure. Optimized tool drive modules and linear guide rails allow the cutting assembly to perform dynamic acceleration and precise alignment. Before the cut, the linear speed of the flying shear blade is synchronized in real-time with the metal strip's feed speed; this perfect synchronization eliminates issues such as burrs and dimensional deviations caused by speed differentials, thereby guaranteeing both high speed and high precision in the cutting process. |

●High-Speed Stacking To address potential bottlenecks in the downstream material collection process and accommodate the high-frequency output of the line, KINGREAL STEEL SLITTER has equipped the system with a dual-stacker as a key downstream component. The entire structure receives sheet metal discharged from the high speed cut to length line and, utilizing the line's automated control program, executes a fully automatic, orderly stacking operation. The stacking process employs a coordinated mechanism combining pneumatic and hydraulic drives to enhance driving force and ensure stack flatness. Additionally, the system is equipped with a dedicated sheet-receiving support assembly; during the descent, a receiving manipulator provides uniform, cushioned support to mitigate impact forces, thereby comprehensively protecting the surface quality of the sheets. Furthermore, the high speed cut to length line incorporates intelligent photoelectric sensors to dynamically regulate the lowering of the stacker and precisely control the vertical gap between the stack surface and the discharge station. This ensures seamless coordination across the entire workflow—from feeding and shearing to stacking—thereby boosting overall automation and the yield rate of finished products. |

The flying shear cut-to-length shearing line is an automated production line for metal sheet processing. It can complete high-precision and high-speed cut-to-length shearing process during the continuous operation of the sheet. It is widely used in the steel and non-ferrous metal processing industries.
1/ Dynamic synchronous shearing
The flying shear coil cut to length machine blade completes the shearing when the sheet moves, and the horizontal speed of the shear blade is strictly synchronized with the sheet speed (the error is controlled within ±0.8mm), avoiding efficiency loss caused by downtime.
2/ Length adjustment mechanism
The proportional relationship between the spindle speed and the feeding speed is adjusted through a variable speed gearbox or a continuously variable transmission.
3/ Intelligent control
PLC or frequency converter (such as GD350 series) is used to realize bus communication, store multiple process parameters and adjust the steel coil cutting machine in real time.
4/ Energy saving and efficient design
The continuous operation start-up flying shear saves 1/3-1/2 energy compared to traditional models, and the steel cut to length line speed can reach 100m/min, which is suitable for sheets with a thickness of 0.3-6mm
Fixed shearing cut to length lines feature a feed stop function at a preset length. When the set length is reached, the fixed shearing cut to length line automatically stops, shearing a section of material before restarting to feed the next section of line that needs straightening and cutting.
1/ Simple structural design for fixed shearing cut to length line
The fixed shearing cut to length line features a relatively simple structure and is easy to operate. This feature allows even beginners to quickly master its operation after a brief training session. The simplified structure not only reduces malfunctions but also facilitates routine maintenance.
2/ Suitable for small-scale production
Although the fixed shearing cut to length line can reach speeds of 50m/min, it is not as fast as other high-efficiency shearing methods. Therefore, this fixed shearing cut to length line is particularly suitable for smaller production operations. For companies that do not require large-scale production, the fixed shearing cut to length line can meet their daily production needs, avoiding the resource waste associated with more efficient equipment.
3/ Adaptability to production efficiency
Since the fixed shearing cut to length line has a maximum speed of 50m/min, it is well-suited for customers who do not have high production efficiency requirements. Small fabricators or startups often seek a cost-effective and efficient production solution. In such cases, a fixed shearing cut to length line provides sufficient cutting capacity without placing excessive pressure on the production process.
4/ Suitable for customers with limited budgets
Due to its lower speed and simple design, fixed shearing cut to length lines require relatively low component specifications and performance. This reduces the technical complexity in manufacturing and design, resulting in a relatively affordable price. Therefore, fixed shearing cut to length lines are an ideal choice for customers with limited budgets, especially startups entering the metalworking industry.
Swing shearing cut to length lines are designed to meet customer needs for custom-shaped sheet metal. Through the automatic swing of the shears, the swing shearing cut to length machine can cut at various angles, effectively processing a variety of shapes such as trapezoids, parallelograms, triangles, squares, and rectangles.
1/ Cutting into different shapes
Swing shearing cut to length lines are capable of cutting a variety of shapes. Equipped with a fixed-length clamping mechanism, the swing shearing cut to length machine accurately cuts the moving strip to the desired dimensions. This process ensures that every sheet is precisely tailored to the customer's exacting specifications. The swing shearing cut to length machine incorporates several innovative technologies, including a floating die-holder backlash elimination system, quick die lock, and quick tool change, significantly enhancing shearing efficiency and precision.
2/ Swing cutting motion for swing shearing cut to length line
The swing shearing cut to length line utilizes an swing cutting motion. By optimizing the cutting path, the swing cutting motion ensures high shear quality while improving production efficiency. This innovation enables the swing shearing cut to length line to maintain high-level cutting performance across a wide range of materials, from thin to thick plates.
3/ High speed swing shearing cut to length line
The swing shearing cut to length line boasts a production speed of up to 80 m/min, fully meeting the demands of efficient production. The speed can be flexibly adjusted to suit various production environments and needs.
