Implementing lean manufacturing to improve compressed gas and liquid filling efficiency

The main focus of this study is to apply the Lean concept and methods to help a compressed gas and liquid filling company find the root causes of slow production as well as identify where and how the gas and liquid are lost and suggest methods for improvement. A careful study of the production process was done by analyzing the setups and layout of current work stations, interviewing employees, conducting time study, drawing work flow charts, value stream mapping and measuring the input and output gas amount. Various wastes such as transportation, motion, and waiting were identified, and gas and liquid leaking stations were found. A new plant layout was provided to help the company improve the production efficiency. The results show that these lean manufacturing initiatives had led to a reduction of travel distance, production lead time and factory floor space.
