Research On Quick Exchange Of Die Based On Lean Manufacturing In W Company

Based on the theories and principles of lean production and SMED, the article analyzed the time and content of robot exchange mould by using flowcharts, value-added and non-value-added concepts, which is the longest time exchange mould in the W company. According to the analysis results and China’s cultural tradition, W company set up goals, and then shorten internal and external exchange time based on the principle of SMED by using5W2H, EMRC and methods of lean production to eliminate waste, finally used fishbone diagram to analyze and reduce debugging time. Through continuous efforts, the time for mould exchange reduced from150minutes to26minutes and we reached the goals set in advance.The results were the sample for small and medium company how to run lean production through SMED.
