Abstract:
This research presents an improvement of a car cigarette lighter socket production
process. The Industrial Engineering (IE) techniques were systematically applied to indentify the
causes of problem. The countermeasures were set up. Experimental design, slide rail redesign,
adjustment of censoring pin probe were applied in order to solve the problems of galling nut and
bolt, spring washer not feeding and body and fuse unit assembly problems, respectively. The
implementation of these countermeasures indicated that defectives were decreased from 468 to 15
pieces per month. The frequency of machine stoppage was decreased from 705 to 16 times per
month which led to significant reduction of the waste in production time. Consequently, the
production rate has increased from 1,730 to 2,122 pieces per shift, and exceeded the production
target of 2,100 units per shift. Thus, it can be concluded that the methodology applied in this
research can efficiently solve the similar problem in the future.
