Core performance and quality improvements

Stable unwinding tension and unwind control

Closed-loop tension control with an adjustable unwind head ensures stable unwind tension, reduces coil offset, waviness, and edge damage, and enhances consistency for subsequent leveling and shearing.

High-precision leveling and alignment

Dedicated leveling mechanism and guiding system achieve precise alignment of thickness, flatness, and width, reducing trimming/cutting errors along the line and improving product quality and yield.

Efficient flying-shear line linkage

Flying shear head cuts quickly and stably with minimal downtime; when paired with the feed system, enables continuous operation, significantly increasing line speed and throughput.

Smooth docking and transport of the loading cart

Designed for seamless interfacing with coils, pallets, and downstream processes, reducing handling time and inventory buildup while improving on-site flow.

Automation interfaces and data interconnection

Supports PLC/SCADA, sensors, barcode/RFID, and seamless integration with robots or conveyors, facilitating automation upgrades and data traceability.

Safety and compliance

Overload protection, emergency stop, limit switches, guard rails and fall-protection structures, enhancing operator safety and meeting industry standards.

Adaptability and flexibility

Suitable for multiple coil diameters, widths, thicknesses and unwinding needs across different materials; modular design enables quick switching and expansion.

Stable energy use and maintenance costs

Efficient drives, low-noise operation, modular components and easily replaceable parts, reducing total cost of ownership.

Surface protection and material-friendliness

Soft-touch surfaces and protective coatings minimize surface scratches during unwinding and protect coil quality.

Customization and on-site adaptability

Based on line speed, coil specifications and site layout, provide customized pallets, fixtures and lift travel to ensure optimal interfacing and line coordination.

Further customization points

Additional customization options can be tailored to meet specific site needs.
