    Product Introduction

    The slitting machine is a key piece of equipment in industry for cutting wide metal or non-metallic coil materials into several narrow strips of the required width along the length direction. Its core working principle is to continuously roll-cut the material through the rotation of the upper and lower circular disc knife shafts.

    The following is a comprehensive introduction to the core features of the slitting and shearing machine:

    Core Structure & Unit Composition

    The core structure mainly consists of upper and lower knife shafts, fixed/movable frames, and a synchronous lifting mechanism. The knife shafts and frames undergo precise processing (such as turning, high-frequency treatment, grinding, and chrome plating, etc.) to ensure the rigidity and accuracy of the equipment.

    • Applicable to coils of various specifications — used for slitting coils into required widths for punch line use through uncoiling, pre-leveling, cropping, slitting and recoiling.
    • Proper layout, easy operation, highly automated and high production efficiency.
    • Adaptable to process cold-rolled and hot-rolled coils, silicon steel coils, stainless coils, colored coils, aluminum coils, and all sorts of plated and coated coils.
    • Widely applied to industries such as automobiles, containers, household appliances, food packing, construction materials, etc.
    • Consists of loading cart, uncoiler, slitter, scrap winder, cropping shear, tension controller and coil recoiler, with loop bridge, pinch and deviation corrector between each machine.
    • A full integration of mechanical, electrical, hydraulic and pneumatic technology.

    Frequently Asked Questions

    What materials can the CR coil slitting line process?
    The slitting line is designed to process a wide range of coil materials, including cold-rolled and hot-rolled coils, silicon steel coils, stainless steel coils, colored coils, aluminum coils, and various plated and coated coils.
    What is the maximum coil thickness this slitting machine can handle?
    Depending on the model, the coil thickness ranges from 0.2mm up to 6mm. For example, the 6×1500 model handles coil thicknesses between 1mm and 6mm, while the 1.2×1250 model is suited for thinner materials from 0.2mm to 1.2mm.
    How many slitting strips can be produced in one pass?
    The number of slitting strips varies by model. The 1.2×1250 and 3×1600 models can produce up to 25 strips per pass, while the 2×1250 model supports up to 15 strips, and the 6×1500 model up to 20 strips.
    What industries is the coil slitting line suitable for?
    The slitting line is widely applied across many industries, including automobile manufacturing, shipping containers, household appliances, food packaging, and construction materials, among others.
    What is the working process of the coil slitting production line?
    The production line follows a sequential process: loading → uncoiling → pre-leveling → cropping → slitting → recoiling. Loop bridges, pinch rollers, and deviation correctors are installed between each stage to ensure smooth and accurate material flow.
    What technologies are integrated into this slitting line?
    This automatic coil processing line integrates mechanical, electrical, hydraulic, and pneumatic technologies, offering high automation, easy operation, and efficient production output suitable for modern industrial applications.
