SMED (Single-Minute Exchange of Die) is a Lean Manufacturing technique designed to reduce setup and changeover times in production processes. The goal is to bring setup times under 10 minutes ("single-minute"), allowing for faster transitions between different products or tasks.
Key Principles of SMED
- Separate Internal & External Setup – Perform as many setup tasks as possible while machines are running.
- Convert Internal Setup to External Setup – Modify tasks so they can be done in advance, reducing downtime.
- Streamline Setup Operations – Use quick-release mechanisms, standard tools and organized workstations.
- Standardize Processes – Create repeatable and efficient changeover procedures.
- Continuous Improvement (Kaizen) – Regularly refine and optimize setup processes.
Benefits of SMED Implementation
- Drastically Reduces Setup Times – Improves production efficiency.
- Increases Machine Utilization – More production time, less idle time.
- Enhances Flexibility in Production – Easier to switch between products
- Reduces Waste & Inventory Costs – Eliminates overproduction.
- Boosts Profitability – Faster setups mean more output and revenue.
