What is Single Minute Exchange of Die (SMED)?

Single Minute Exchange of Die (SMED) is a lean methodology for reducing set-up times in production. The aim is to reduce changeover times to less than ten minutes in order to increase the flexibility and efficiency of production processes.

Advantages of SMED:

  • Reduced set-up times: Shorter changeover times allow production lines to be adapted to new products or batches more quickly.
  • Increased flexibility: Faster set-up times increase the flexibility of production, making it easier to adapt to changing market requirements.
  • Increased productivity: Shorter set-up times lead to less downtime and increase the overall efficiency of production processes.
  • Cost reduction: Reduced set-up times reduce production costs through more efficient use of machines and manpower.
  • Quality improvement: Faster changeovers allow for more frequent product changeovers and smaller batch sizes, which improves quality control.

How does SMED work?

  • Analysis of current set-up times: Recording and documentation of existing set-up processes to identify optimization potential.
  • Separation of internal and external set-up processes: Separate internal set-up processes (which can only be carried out when the machine is at a standstill) from external set-up processes (which can be carried out during machine operation).
  • Standardization and optimization: Standardize setup processes and implement measures to reduce internal setup times.
  • Continuous improvement: Regular review and adjustment of set-up processes based on the results and new findings.

Conclusion: Single Minute Exchange of Die (SMED) is an effective lean methodology for reducing set-up times in production. By reducing changeover times to less than ten minutes, companies can increase their production flexibility, boost efficiency and cut costs.
