Porsche bumper assembly lines, E4 and E3
The machine
Two assembly machines for Porsche front and rear bumpers, covering several models and a large number of production variants on the same equipment. The hard part is not the assembly — it is that every variant needs a different sequence, different fixture positions and different operator instructions, and the line has to switch between them without a changeover stop or a mistake by the operator.
What HAL Automation delivered
Complete machine programs on Siemens S7-1500 with WinCC Unified, automatic variant management so the sequence adapts itself to the model arriving, operator guidance on a second monitor with step-by-step instructions, and coordinated control of seventeen Festo servo drives positioning seventeen independently controlled support pads.
How it was approached
Variant data held as parameter sets rather than branched logic, so adding a model is a data entry rather than a program change — the difference between a machine that survives the next facelift and one that has to be reprogrammed for it.
