강건성을 고려한 모니터 장식패널 사출품의 휨 최소화

Abstract

An optimal robust design methodology has been developed to minimize the warpage in a decorating panel of monitor molded by the plastic injection. For the associated methodology, the Taguchi's Design Of Experiment(DOE) based on orthogonal arrays and Signal-to-Noise Ratio is combined with commercial simulation tools for injection molding. An optimal robust design solution is statistically resulted from the computational simulation. The related experiment was done for evaluations of the warpage in the decorating panel part of monitor. This research showed that the warpage under the applied optimal design conditions was comparatively reduced.
