At the end of 2012, Shifeng Parts Factory of Dongfeng Dana Axle started SMED (quick change and improvement) work in the six workshops of the whole plant. It is understood that SMED refers to the rapid replacement of mold changing time within a single minute to complete the replacement of processing molds and tooling. It is a non-value added activity at the production site. The survey data showed that before the rapid change activity, the time spent looking for molds, tooling, and tools accounted for 50% of the changeover time, the equipment adjustment time accounted for 35% of the changeover time, and the setting and installation time accounted for 15% of the changeover time. After SMED activities are conducted, the search time can be completely eliminated, and the adjustment time can be reduced. The time for changing the model can be reduced by at least 50%. SMED originated in Japan in the early 1950s and developed in the Toyota Corporation. It helped Toyota to shorten the product switching time from 4 hours to 3 minutes, which promoted the improvement of production efficiency.
