Process stability: rigidity, guidance, repeat accuracy

Process stability in deep drawing: The invisible factors that cost ppm and OEE

In deep drawing, it is often not “more force” that is decisive, but how the force is applied to the tool and strip:

  • Frame and drive stiffness reduce deflection and varying conditions in the drawing process
  • Precise ram guidance minimizes tilting → Uniform tool contact, better dimensional accuracy, better tool life
  • Reproducible stroke kinematics ensure constant conditions from stroke to stroke – a real advantage in series production

The result is not just “nicer parts”, but hard key figures:

  • Fewer cracks/wrinkles (more stable process window)
  • Less rework
  • Less tool stress → Longer tool life
  • More stable quality across shifts and operators
