Hauptvorteile und Hauptmerkmale

Professional Arc Forming Technology, Perfect Curvature

The core highlight of this machine is its specialized arc-forming roller system, which is professionally designed and calibrated to produce uniform, smooth curved roof panels with adjustable radius (from 5m to 50m). The multi-stage gradual forming process ensures the arc is natural and consistent, with no wrinkles, cracks, or deformation, avoiding the common problem of uneven curvature in traditional forming machines. Finished curved panels have a sleek, aesthetic appearance, perfectly matching the design needs of various architectural styles, from modern to classic.

High-Precision Forming, Stable Product Quality

Driven by imported servo motors and high-precision positioning encoders, the machine controls product size tolerance within ±0.3mm, ensuring every curved panel has consistent arc radius, width, and thickness. The forming rollers are made of high-grade 45# carbon steel, processed by precision grinding and hard chrome plating, featuring excellent wear resistance and long service life. The optimized forming route protects the panel surface from scratches, keeping it smooth and intact, greatly improving product qualification rate and market value.

Fully Automatic Production, Ultra-High Efficiency

Equipped with a PLC intelligent touch screen control system, hydraulic automatic uncoiler, and servo feeding system, the machine realizes fully unmanned continuous production with a stable working speed of 8-20m/min, supporting 24-hour uninterrupted operation. Operators only need to set arc radius, production length, and quantity with one click, and the machine completes the entire production process automatically. The built-in flying shear cutting function enables fixed-length cutting without stopping the line, reducing labor input by over 60% and shortening order delivery cycles.

Heavy-Duty Stable Structure, Long Service Life

Built for long-term industrial use, the main frame adopts thickened high-strength welded steel plate with overall annealing treatment, featuring high rigidity, excellent shock resistance, and zero deformation even under continuous high-load operation. The transmission system uses high-quality gearbox and durable chain drive, running smoothly with low noise and minimal wear. Key electrical components adopt international premium brands such as Siemens and Schneider, guaranteeing stable operation, low failure rate, and reduced downtime.

Wide Compatibility & Strong Versatility

This machine is highly adaptable to various metal coil materials, including color-coated steel, galvanized steel, aluminum-zinc coated steel, and aluminum alloy, with a material thickness range of 0.4mm-1.2mm, covering mainstream raw materials for curved roof panels. It supports adjustable arc radius and panel width, and can produce both single-curved and double-curved roof panels, adapting to different architectural design requirements. It also supports customized profile design to meet regional construction standards and project-specific needs.

User-Friendly Operation & Low Maintenance Cost

With an intuitive English touch screen interface, parameter setting and daily operation are simple and clear, and new operators can master full operation after short-term training, no professional technical background required. The system is equipped with fault self-diagnosis, emergency stop, and automatic alarm functions, enabling quick troubleshooting and ensuring operational safety. Daily maintenance only requires regular lubrication and routine inspection, with simple steps and low long-term maintenance costs.
