Case2 Production cycle shortened over 85%, the per capita efficiency increased 33.9%, the defect rate decreased 61.7%. 1.It is a high-tech enterprise integrating the research and development, manufacturing, sales and service of new energy products. It has been deeply engaged in the application field of lithium-ion battery energy storage for over a decade. The company has established a lithium-ion battery positive electrode material production base, a cylindrical cell production base and a PACK intelligent manufacturing base. 2.In 2021, in the face of the rapid development of the lithium battery new energy industry, in order to quickly increase production capacity and seize the market, the company, on the one hand, invested heavily in building new factories, while on the other hand, it was confronted with the problem of lax basic management. 3.The on-site actual investigation revealed that other workshops should start with 5S management, but the PACK production line needs to begin with the design of a lean production line; otherwise, the 5S management of the PACK production line will definitely fail. This led to the initiation of the enterprise's PACK lean line design project.
 1.Aiming to improve the battery case production line of the mainstream product, a project was initiated. The original process was thoroughly examined, and the production line balance design was optimized. The "false" flow line was transformed into a "true" flow line single-piece flow production method. In addition, a post-production material supply method was adopted, which enhanced the value-added ratio of the production process. 2.Achieving performance: The production cycle has been shortened by over 85%, the per capita efficiency has increased by 33.9%, and the defect rate has decreased by 61.7%.
