Applying Lean Tools in The Shaped Plastic Products Industry: A Case Study

This study applies techniques such as Lean Manufacturing, 5S, Line of balancing, and production bottleneck analysis to tackle the problems of optimizing production resources, minimizing the Work-in-process, eliminating motion waste, and the 5S issues within the manufacturing area. Further, a case study on the production and sales of the shaped plastic packaging company is discussed. The result obtained was that the lead times of all the items improved, the WIP backlog problem was reduced in the production, and the LOB (line of balancing) index of the productions, especially the LOB of the “TET TIN” and the “SPRING ROLL,” increases of 19.1% and 12.09%, respectively.
