Abstract: ABC Corporation is a Taiwanese company that manufactures metal, other related products, and industry in need of thin sheet metal fabrication. The main objective of the study is to improve the M450G1010Z08 that occurred in press brake section, which is the primary problem of the company. The researchers used the Six Sigma Methodology as a technique of reducing quality issues. The research design used in the study is applied research. Based on the result of the study, the researchers found out through stratification process that the main problem was the wrong dimension of M450G1010Z08. In the measure phase, the researchers measured the wrong dimension defects using binomial process capability, which resulted in processing Z value of 1.08, indicating the process is not capable. In the analyze phase, researchers found out that the root cause of the problem is the open size of mould that exceeds 0.20 mm in the front side. In the improve phase, the procedure for modification of mould was done to meet the project target from 14.12% to 4%. After the implementation, the researchers found out that the wrong dimension of M450G1010Z08 was reduced from 14.12% to 2.12%. Also, the process Z increased from 1.08 to 2.03 and investigated that the process performance is capable after the implementation of the improvement. The improvement was done to improve work instruction for modification of the open size of the mould.
