摘　　要：对手机壳体塑料件进行了常规注射成型CAE研究,分析存在较为严重的表观质量问题。通过采用高光成型技术,以沉降指数、体积收缩率和翘曲变形为质量指标,利用正交试验和多目标综合平衡法分析研究得出该产品的最佳成型工艺参数组合。分析结果表明,高光注射成型技术在改善薄壳多孔塑料件缺陷方面比常规注射成型有着更大的优越性。CAE research of conventional injection moulding on a mobile phone shell was carried out and the serious apparent quality problems were analyzed, Then through＇ high-gloss injection molding technology, selecting sink index, volumetric shrinkage and warpage as the main quality indexes, the optimum injection molding parameters combination was obtained by using orthogonal experiment and multi-objective integral balance method.The analysis results showed that high-gloss injection molding had more advantages in improving defects of thin shell injection molding parts with holes compared with conventional injection molding.
