Abstract:
This engineering project is designed to improve the operation of the production of copper pipe in air conditioners of the sample factory. Therefore our team decided to apply method of work study in collecting data and studying the Auto Brazing process. The Auto Brazing station operates 3 man and has a production rate higher than the demand or the production is too high, should review the production process in this station. Why-why analysis as a tool for finding the root cause and by using also ECRS by using simplified the equipment
that added to facilitate the blower area dried faster and combined the work of the blowing. Number of operator is reduce from 3 man to be 2 man. The cycle time from 25 seconds to 28 seconds and working efficiency from the before improvement compared to the cycle time, the operator1 from working 10 seconds is 40% after the improvement, working 23 seconds is 82% and the operator2 from working 16 seconds is 64% after the improvement, working 21 seconds is 75%. This improvement also decreases cost from 76,800 baht per
month to 51,200 baht per month.
