Abstract
Thin-wall injection molding parts have the shrinkage distortion problem, this is mainly caused by the setting of processing parameters. Gray relational analysis and Taguchi method were applied to obtain the combination of processing parameters that could produce the product with optimal multiple quality characteristics. We used gray relational analysis to solve the single quality characteristic problem of Taguchi method and used the response graph of gray relational analysis to receive the optimal processing parameters combinations, which would produce the product with multiple quality characteristics. Finally, the confirmation experiment proved the reliability and reproducibility of this experiment with 95% confidence interval.
