3×1650MM Slitting and Cut to length compound production line

Product Overview

The 3×1650MM Slitting and Cut to length compound production line is an integrated steel coil processing solution designed for medium-gauge wide coil handling. It is capable of processing coils up to 3mm thick and 1650mm wide, converting them into both precision narrow strips and flat plates in a single continuous operation. This line is specifically optimized as a critical feedstock preparation step for high-volume manufacturing processes including stamping, structural roll-forming, tube-making, and panel manufacturing. It targets large-scale steel service centers, automotive structural parts manufacturers such as EV battery casing producers, home appliance makers, and heavy-duty construction equipment fabricators, providing a streamlined, efficient way to prepare raw steel materials for downstream production.

Core Functions & Processing Capabilities

This compound production line combines two essential steel coil processing functions into one integrated system: slitting and cut-to-length. The slitting function precisely cuts wide steel coils into narrow strips of specified widths, while the cut-to-length function shears coils into flat plates with accurate, consistent lengths. The line can handle medium-gauge coils up to 3mm thick and 1650mm wide, making it suitable for a wide range of steel materials used in automotive, home appliance, and construction equipment manufacturing. By integrating these two processes, it eliminates the need for separate processing lines, creating a continuous workflow that reduces material handling and speeds up feedstock preparation.

Key Problem-Solving Features

1. Bottleneck Elimination: By combining slitting and cut-to-length functions into a single line, this equipment eliminates production bottlenecks caused by separate processing steps. It reduces multiple material handlings, as coils only need to be loaded once for both processes, and also minimizes factory floor space requirements compared to installing two independent lines.
2. Material Flatness Improvement: Integrated leveling technology is applied prior to cutting, which resolves common material issues such as internal stress, camber, and surface waviness. This ensures that the finished strips and plates are flat and uniform, meeting the strict flatness requirements of downstream stamping and roll-forming processes.
3. Downtime & Quality Reduction: The integrated design minimizes downtime associated with frequent changeovers between separate slitting and cut-to-length lines. Additionally, it prevents edge burrs caused by poor tension control during shearing, ensuring clean, high-quality finished products that require less post-processing.

Performance Advantages

1. Space & Labor Efficiency: Equipped with an all-in-one automated PLC/HMI system, this production line reduces factory footprint by up to 40% compared to using two separate lines. The automated operation also cuts labor costs by over 30%, as fewer operators are needed to monitor and control the processing workflow, and manual material handling is significantly reduced.
2. Precision Tolerance Control: The line achieves strict width tolerances down to ±0.05mm and length tolerances of ±0.3mm. This high level of precision ensures flawless weld quality in downstream tube-making and panel assembly processes, and minimizes post-processing rework caused by dimensional inaccuracies.
3. Yield & Delivery Improvement: Advanced servo feeding and alignment systems reduce raw material scrap by 3-5%, as they ensure precise positioning and cutting of coils, minimizing waste from misaligned or inaccurate cuts. Furthermore, the integrated processing workflow accelerates delivery cycles for multi-specification orders, as the line can quickly switch between producing different strip widths and plate lengths without the lengthy changeover times of separate lines.

Target Customer Groups

This production line is designed for large-scale manufacturing and processing enterprises, including large-scale steel service centers that provide processed steel materials to various industries, automotive structural parts manufacturers especially those producing EV battery casings which require high-precision steel components, home appliance producers that need flat steel plates for appliance bodies and structural parts, and heavy-duty construction equipment fabricators that rely on durable, accurately cut steel strips and plates for equipment frames and components.

Application Scenarios

The 3×1650MM Slitting and Cut to length compound production line serves as a critical feedstock preparation step in multiple high-volume manufacturing scenarios. It is used to process steel coils into precision narrow strips for structural roll-forming and tube-making processes, which are essential for producing automotive chassis parts, construction equipment frames, and industrial pipes. It also cuts coils into flat plates for stamping and panel manufacturing, supporting the production of EV battery casings, home appliance bodies, and heavy-duty equipment panels. Its integrated design makes it ideal for facilities with limited floor space that need to handle high volumes of steel coil processing efficiently.

Industry Pain Points Solved

This compound production line addresses several key pain points in steel coil processing. It solves the problem of production bottlenecks caused by separate slitting and cut-to-length lines, which often require multiple material transfers and lead to delayed workflow. It resolves issues with material flatness, such as internal stress and surface waviness, which can cause defects in downstream stamping and forming processes. Additionally, it reduces downtime from frequent line changeovers and eliminates edge burrs caused by poor tension control, improving product quality and reducing rework costs. It also addresses the inefficiencies of separate lines, which take up excessive factory space and require more labor, by providing an all-in-one automated solution that saves space and cuts labor costs.
