Increasing competitiveness in the manufacturing industry demands that companies continually seek ways to improve the efficiency of their processes. One of the most effective techniques for optimizing setup time and, consequently, increasing productivity is SMED. But what exactly is SMED and how can it be implemented in your operation? Let's explore.

What is SMED?

SMED, which stands for Single Minute Exchange of Die , is a methodology developed by Shigeo Shingo, one of the forerunners of the Toyota Production System. The main objective of SMED is to drastically reduce the time required for tool changes and machine setups, enabling the production of smaller batches and increasing production flexibility.

Why is SMED important?

In traditional manufacturing, setup times can be long and costly, resulting in downtime that negatively impacts productivity and efficiency. By reducing setup time, companies can:

• Increase flexibility : Produce smaller batches and respond more quickly to market demands.

• Reduce inventory : Decrease the need for large safety stocks.

• Improve machine utilization : Maximize the productive uptime of machines.

• Increase overall efficiency : Reduce costs and increase productive capacity.

How to implement SMED?

The implementation of SMED can be divided into four main stages:

1. Analysis of the Current Setup : Detailed observation and recording of the current setup process to identify all activities involved.

2. Separation of Internal and External Activities:

   • Internal Activities : Tasks that can only be performed while the machine is stopped.

   • External Activities : Tasks that can be performed while the machine is operating. The goal is to convert as many internal activities as possible into external ones.

3. Convert Internal Activities to External Activities : Modify setup procedures so that more tasks can be performed while the machine is in operation. For example, preparing necessary tools and materials before the machine is stopped.

4. Streamlining Internal Activities : Simplify and optimize remaining internal activities so that they can be performed more quickly and efficiently. This may include the use of quick-connect tools, ergonomic improvements, and standardization of procedures.

Benefits of SMED

Implementing SMED brings several tangible benefits to manufacturing operations:

• Reduced Setup Time : Setup times can be reduced from hours to minutes.

• Increased Productivity : Less downtime means more time for production.

• Greater Flexibility : Facilitates the production of a wider variety of products in smaller batches.

• Cost Reduction : Shorter setup times reduce operating costs and increase efficiency.

• Quality Improvement : Faster and more efficient processes reduce the chance of errors and defects.
