Abstract:
To reduce waste reduction in micro cable manufacturing by applying lean six sigma approach. Current working condition in this electronic manufacturing has high process waste which result in the production cost is very high at 94.8% of selling price. The purpose of this research is to reduce the waste in the production line of micro coaxial cable and solving the problem by apply lean six sigma principle. This research consists of 5 steps (I) Identifying problem phase, analyzing causes which the project B004 is chosen as it has the highest cost structure. (II) Measuring phase, is to identify the non-value added activity does. The proportion of this nonvalue added activity is as high as 65% of all activities. Moreover the problem of waste is a problem that occurs in short circuit. (III) Analysis phase was to analyses seven waste according to lean concept. (IV) Improvement phase was to find solution to the problem, design process used ECRS principles to reduce waste from over production, of production layout process is to reduce waste in transportation. Reducing the waste of unnecessary inventory adopted the principles of 5S. Reduction of failure in production process followed by design of experiment after all solution to waste reduction were identified, they were implement by training employees. (V) Control phase, is to monitor and control the defined parameter input from the experimental and control the standard practices to all employees. The improvement result has shown production cost is reduced from 48.25 baht per piece to 42.54 baht per price or by 11.83% and productivity up from 3700 piece to 4090 piece or 9.45%
