4000mm hydraulic bending machine for roofing sheet

Our 4m hydraulic bending machine from Hebei Xinnuo effectively resolves core pain points troubling metal fabrication and roofing processing factories worldwide. Many small and medium workshops struggle with unstable bending angles, inconsistent finished workpieces and massive material scrap caused by poor machine rigidity and outdated hydraulic systems, which greatly raises production cost and reduces profit margin. Besides, traditional bending equipment features complicated operation, requiring skilled veteran operators and leading to high labor expense; frequent hydraulic oil leakage, overheating and high maintenance downtime also halt continuous production schedule and delay customer orders. In addition, ordinary bender cannot adapt to diversified raw materials including color steel, galvanized sheet and aluminum coil, limiting clients’ product expansion and market development. Designed targeting above drawbacks, Xinnuo 4-meter hydraulic press brake adopts integrated heavy steel welding frame with vibration aging treatment to eliminate internal stress, avoiding long-term frame deformation and angle deviation during long-hour continuous working. Optimized closed hydraulic system cuts oil leakage and overheating failure sharply, lowering daily maintenance workload and spare parts cost significantly. Equipped with simplified foot pedal control plus optional digital backgauge adjustment system, it lowers operation threshold; new workers can master basic operation within half an hour to cut skilled worker hiring cost. It supports bending thickness from 0.3mm to 2.0mm for multiple metal sheets, helping users expand product categories without purchasing extra equipment. With stable 80-ton hydraulic output and ±0.5mm bending precision, our machine minimizes defective rate and raw material waste directly. We supply 12-month global warranty and remote technical guidance, solving after-sale maintenance anxiety for overseas buyers. Widely used for roof panel, gutter and metal cabinet bending, this cost-effective hydraulic bending line becomes ideal upgrading choice for small & medium metal processing plants from Middle East, Southeast Asia and Africa.
