Through analysis and evaluation, we found out three main issues in W company:the man-machine coordination with the low utilization of personnel; abnormal working hourswas focus on the exchange of mold, the time to change a mold was too long;there was stillroom for production quality improvement. According to three issues, we have planned threeimprovement programs: improve utilization of personnel by using man-machine analysis;implementation of SMED to improve the speed of changing mold; quality improvementactivities to enhance the production yield. By implementing the improve program, weeliminated a lot of waste and non-value-added jobs and improved the production efficiency inW company. We also reduced the production cost and enhanced product competitiveness.Thispaper would have a positive significance for implementation of lean production project insimilar manufacturing enterprises.
