300Tx6300mm Bending Machine

  • Ultra-large Heavy-duty Sheet Metal Bending

    Specialized in one-time precision forming of 6300mm ultra-wide and thick metal sheets (Q235/Q355 low alloy steel, 304/316 stainless steel, high-strength aluminum alloy). The 300T high bending force and full-length dynamic anti-deflection compensation meet the forming requirements of ultra-wide thick plate structural parts, avoiding secondary bending and ensuring high dimensional consistency of large workpieces.

  • Engineering & Heavy Machinery Manufacturing

    Processes large bent structural parts for excavator/loader large arm panels, crane main beam enclosures, mining machinery body shells and construction hoist overall frames. The 6300mm long bending length and X+Y double-axis back gauge realize one-time forming of ultra-large workpieces, matching the high rigidity and precision requirements of heavy engineering machinery structural components.

  • Shipbuilding & Container Production

    Bends ultra-wide thick sheets for ship hull bulkheads, deck structural parts, container side/top/bottom plates and marine equipment shells. The multi-point synchronous pressing and real-time hydraulic compensation ensure no warping, deformation or angle deviation of large-width sheets during bending, meeting the strict welding and assembly tolerance requirements of ship and container products.

  • Steel Structure & Large-scale Building Decoration

    Forms 6300mm wide steel plates into large building steel structure beams/columns, bridge guardrail components, high-rise building curtain wall main frames and municipal engineering large metal structures. The high positioning accuracy (±0.05mm) ensures the consistency of bending angles and sizes of large steel structure parts, improving the on-site assembly efficiency of large-scale building projects.

  • Power & Large-scale Industrial Equipment Production

    Bends ultra-wide thick sheets for wind power tower sections, large transformer outer covers, thermal power boiler accessories and large-scale industrial equipment shells. The optional CNC control system supports automatic batch processing of large bent parts, and the independent oil cooling system ensures stable and continuous operation of the equipment for long working hours, suitable for mass production of large energy equipment components.

  • Special Vehicle & Heavy Container Fabrication

    Processes large bent parts for semi-trailer body panels, heavy truck cab frames, special transport vehicle enclosures and large metal storage containers. The 400mm deep throat depth and 600mm maximum open height adapt to the bending of large and complex-shaped workpieces, realizing integrated forming of large structural parts and reducing the number of welding seams.
