Abstract: The objective of this independent study was to focus on the efficiency improvement of raw rubber sheet lean manufacturing process of Phuping Rubber Limited Partnership located in Chiang Rai province. The qualitative data was collected from the target group which contained the population of business owners and 9 staffs. The study sought to eliminate and reduce processes that do not add value, wastes, waiting time, unnecessary movements in the production process, and work that must be revised. Achieving these factors will lower production costs, increase inspection, and improve all processes. The tools used in this research consisted of the Value Stream Mapping (VSM) of the raw rubber sheet manufacturing process before and after improvement, as well as schedule records and in – depth interview. The data was analyzed by using qualitative data. Results of the study revealed that eliminating waste by using lean manufacturing with ECRS and 5S approaches reduced total production time from 751 minutes to 525 minutes – a reduction of 226 minutes. Production of rubber sheets also increased from 85.93 percent to 95.10 percent, while the quality of rubber sheet production improved from 82.70 percent to 94.50 percent. The results showed that sheet waste or defects decreased from 31.90 percent to 5.85 percent. The revenue increased from 1,059,072 Baht to 1,209,344 Baht, an increase of 150,272 Baht equivalent to 6.62 percent. These results underscored the effectiveness of incorporating lean manufacturing to increase productivity, satisfying the objectives of the process improvement.
