Tandem hydraulic press brakes address a critical manufacturing challenge: how to bend extremely long metal sheets and structural components that exceed the working length of any single machine. A tandem configuration synchronizes two or more press brakes operating side by side, sharing a common control system to coordinate ram movement, backgauge positioning, and crowning compensation across the combined working length. Tandem press brakes extend bending capacity to handle extra-long parts, increase tonnage capacity, and offer switchable individual or collaborative operation modes for strong production flexibility. The flexibility of tandem operation is a key advantage. When processing ultra-long sheets such as 12 meters or longer, the two machines work in coordination through a shared control system, operating as a single, unified press brake with exceptional precision. When not processing long sheets, the two machines can be used separately to handle different small tasks simultaneously, effectively doubling production capacity for standard-size parts. This dual-mode capability maximizes equipment utilization and provides outstanding return on investment. The tandem press brake adopts full closed-loop electro-hydraulic servo control technology, with slider position fed back to the CNC system through bilateral grating scales. The CNC system adjusts the opening size of synchronous valves according to feedback signals to control oil flow, ensuring Y1 and Y2 axes run at the same frequency and maintain parallelism across the entire combined length. The CNC system automatically adjusts deflection compensation based on sheet metal conditions, ensuring uniform angle and length across every workpiece. The combined design of a tandem press brake is more space-saving than a single very large press brake, as multiple smaller machines can be arranged more efficiently in typical factory layouts. Tandem press brakes are ideal for aerospace applications requiring large aircraft parts such as wing sections or fuselage panels, shipbuilding for forming structural components requiring extra length, construction for producing long metal beams and columns, and general heavy fabrication for parts that exceed standard machine lengths. Standard configurations include 2-100 ton by 3200mm, 2-125 ton by 3200mm, 2-160 ton by 3200mm, 2-200 ton by 3200mm, and 2-300 ton by 3200mm, with custom configurations available. The standard backgauge is 2-axis, with 3-axis or 4-axis post-gauge systems available for complex-shaped workpieces.
