1. LEARN BY YOURSELF & CHALLENGE YOUR WAY OF DOING
WHY
​
Single-minute exchange of die (SMED) is a method for reducing waste in a manufacturing process. It provides a rapid and efficient way of converting a manufacturing process from running the current product to running the next product.
WHAT
​
SMED (Single-Minute Exchange of Dies) is a system for dramatically reducing the time it takes to complete equipment changeovers. The essence of the SMED system is to convert as many changeover steps as possible to “external” (performed while the equipment is running), and to simplify and streamline the remaining steps. The name Single-Minute Exchange of Dies comes from the goal of reducing changeover times to the “single” digits (i.e. less than 10 minutes).
BENEFITS
​​
-
Lower manufacturing cost (faster changeovers mean less equipment downtime)
-
Smaller lot sizes (faster changeovers enable more frequent product changes)
-
Improved responsiveness to customer demand (smaller lot sizes enable more flexible scheduling)
-
Lower inventory levels (smaller lot sizes result in lower inventory levels)
-
Smoother startups (standardized changeover processes improve consistency and quality)
