When a sheet‑metal blank reaches the stamping press on the body‑shop line, the operator presses the load introduction button to start the forming stroke. The button acts as the final human cue that releases the hydraulic pressure, allowing the press ram to clamp the tool and apply the required force at exactly the right moment. By linking directly to the machine’s PLC, the button guarantees that the load is introduced only after the blank is correctly positioned by the handling robot, preventing mis‑feeds and protecting the tooling. This precise timing is essential for high‑speed body‑panel production, where cycle times are measured in seconds and any deviation can cause costly rework. The same principle is used in power‑train assembly stations, where the button initiates the torque‑application phase of engine‑mount installation, ensuring that the load is applied consistently across each unit. In both cases, the load introduction button provides a simple, ergonomic interface that translates an operator’s intent into a controlled mechanical action, keeping the line moving without interruption.
