Why use SMED ?
The SMED concept appeared in the late 1950s and early 1960s. It was developed by Shigeo Shingo together with Mazda, Mitsubishi, Toyota. The need to implement a fast and efficient method of change came after the analysis of the process of injection / pressing of automotive components. Through the implementation of SMED, the production concept has changed, offering them flexibility and reduced production costs.
Single Minute Exchange of Die or in short S.M.E.D. : is one of the many methods of reducing losses (MUDA) in production processes.
SMED presents a fast and efficient way to change (Changeover) from the existing product in line to a new product.
Changeover is the process of transforming a line or machine from the production of the current part to the production of a new part.
The terms changeover and set-up are often perceived as the same thing, but this perception is wrong.
Setting up is just one step in the change process. The change can be divided into 3 steps (the 3 Ups):
1. Clean-up: represents the removal of the current product from the line by disposing of the materials and components necessary to make this product.
2. Set-up: represents the transformation of the equipment for the new product.
3. Start-up: represents the fine adjustments that must be made after the equipment has been started.
Advantages of implementing SMED through workshops:
- Reduced downtime
- OEE growth
- Improving productivity
- Flexibility
- Short change time
- Reduction of stocks
- Space reduction
- Production leveling
- Improving working conditions
