Defect reduction of bracelet in the production process using ECRS

Abstract

This study aims to find solutions to reduce defect of bracelet in the production drying process after the anti-tarnish plating process. Using an analysis and problem-solving approach based on ECRS principles, the results revealed that dent waste was 6.67 percent, the normal production time was 5.45 hours, rework was 1.76 hours the total time of production process was 7.21 hours per each production cycle. The researcher proposed 2 solutions to reduce the defects as follows: Solution1: using the up-down wind direction for drying the bracelets. After the experiment, it found that 1.83 percent of defect reduced by 4.84 percent, production time was 6.35 hours, rework was 0.77 hours, the total production time was 7.12 hours per bracelet production cycle, decreased by 0.09 hours, accounting for 1.25 percent. For the second solution, set the drying step for each bracelet, one by one. After the experiment, no defect was found in the production drying process, reduced by 6.67 percent, production time was 6.70 hours, reduced by 0.51 hours, accounting for 7.07 percent.
