(Single Minute Exchange of Die)

The method is designed to reduce the time for conversion through the rationalization of set-up activities. The name is derived from the first letters of English words: Single Minute Exchange of Die. The conversion itself does not add the value of the product and must be perceived as a waste. Conversion is divided into two groups about activity regarding conversion:

  • Internal – these are activities that are possible to be performed (may be performed) only when the machine is not working
  • External – these are activities that are possible to be performed without stopping the machine: in other words, when the machine is working.

There are four stages of the method implementation:

  1. Preparing
  2. Differentiating between internal and external conversion
  3. Transforming the internal conversion to an external one
  4. Rationalizing all aspects of conversion
