Key Observations

  • Direct conveyors require highly balanced processes

  • Buffers absorb cycle time differences

  • Buffers improve predictability rather than speed

-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Which Option Fits Your Line?

  • Stable products → Direct conveyor

  • Frequent interruptions → SMT buffer

  • Manual + auto mix → SMT buffer
