Improvement to Increase Efficiency in Producing Plates of Coil Component

Abstract

The objectives of this research were to: 1) find the guidelines to improve the efficiency of the plate production process and 2) increase the efficiency in plate production process. The data were obtained from the brainstorming discussion among production engineers, chief of Plate Section, and machine operators. The study of the current situation found that there were delay experiences whilst waiting for plate parts used for the coil assembly. Analysis of the plate production process showed that the forming process was the longest in terms of time taken due to the interaction required between human workers and machines. Therefore, a man and machine chart was used to analyze the working proportions and ECRS principles were used to analyze and find ways in improving and reducing waste in the plate forming process. This study focused on two parts of plate forming of coil ventilator structure, i.e. 1) the forming of the ventilator structure and 2) the forming of the left plate and the right plate.

After the improvement highlighted by the study, the process cycle time of the plate forming was reduced as follows: 1) the forming time of the ventilator structure was reduced from 1,412 to 973 seconds or 31.09% reduction and 2) the forming time of the left plate and the right plate was reduced from 2,346 to 1,684 seconds or 28.22% reduction.
