The application of FMEA to reduce defective rate from broken filament defects in the Direct Spin Drawing process

Abstract

This paper presents a methodology to reduce defective rate from broken filament defects in the Direct Spin Drawing process. The Failure Mode and Effects Analysis (FMEA)was used to analyze the causes of defect and prioritize those causes,leading to the pertinent improvement methods.The improvement method involved the development of better methods for detection of failures occurred in machine parts. After improvement, the defective rate from broken filament defects significantly was reduced from 3.35% to 1.76%.
