The study examines the role of lean manufacturing principles of Single Minute Exchange of Die (SMED) and Kanban in augmenting productivity through metrics of reduction in inventory, changeover time and units produced per lot. The paper uses case study-based approach to examine the significant effects of SMED and Kanban on an emblem manufacturing setup. Primary data pertaining to emblem produced in maximum quantity was gathered. The data collection process involved identifying internal and external activities during injection molding process. Analysis of the data revealed which of the activities can be removed and which can be standardized in order to reduce setup time. The results showed that SMED method facilitated a reduction of 53% in setup time. Significantly, the method saved about 25 min in setup time per batch, leading to a total saving of 750 min per month. In addition, metrics of number of units produced daily and work-in-process inventory showed marked improvements, as the results showed a reduction by 25% and 50% respectively. The application and recording of beneficial outcomes of both SMED and Kanban in an automotive parts manufacturing company, which forms a vital link in the entire supply chain, makes the contribution of this study novel.
In the wake of increasing competition and ever-demanding customers, manufacturing has been under enormous pressure to produce a variety of products in smaller batches at reduced prices. However, demand for increased variety forces machines to undergo changeover frequently, that is, the time spent in preparing machines between two production orders increases (Arasanipalai et al., 2014). During this time, the machine is in a dormant state, not producing anything. This time is termed wasteful activity (Carrizo and Campos, 2011). To reduce this waste, manufacturing operations are designed to produce a type of product in large quantities before switching to production of another type.
