摘要：
Plastics injection molding technology is widely used in industrial products. However, the product quality is inconsistent and variance is significant in the conventional plastic injection molding process. This phenomena occurs due to the absence of a systematic method for maintaining stable processes. If this issue can be resolved, product quality can increase to higher levels and further reinforce industry competitiveness. This study uses a combination of the Taguchi method and principal component analysis (PCA) to improve the real product quality of cosmetic containers produced by conventional plastics injection molding processes through optimizing the parameters. This study determined that when all the values of the three quality characters were moved to the intervals of specification, the standard deviation reduced by approximately 6 % to 10 %. Additionally, PCA can be effectively applied to problems with multiple quality characteristics to establish an integral solution. Furthermore, the holding pressure can be considered as an adjustment factor to the process mean. Through analysis of variance, this study determined that the material melting temperature, holding pressure, and injection location significantly affected the size of the finished product.
