汽车开关面板注射成型工艺参数优化

针对汽车内饰件开关面板这类制品在注射加工过程中容易产生翘曲变形的缺陷，采用计算机CAE模拟技术和 Taguchi试验相结合的方法，以翘曲变形作为质量指标，把注射过程中的模具温度、熔体温度、注射时间、保压时间和保压 压力这5个工艺参数作为影响制品翘曲变形的影响因素，运用CAE软件对不同水平下各工艺参数进行注射成型的数值 模拟。结合极差分析法、信噪比法优化得到最优工艺参数组合来减少翘曲量。将得到的最优工艺参数组合进行CAE模 拟，发现开关面板的翘曲变形得到较大的改善。通过实际注射试验验证了CAE模拟的结果。

Optimization Analysis of Switch Panel Injection Molding Process Parameters on Taguchi Test

According to warpage deformation of the automotive interior switch panel in injection molding, combined the computer CAE simulation with the Taguchi test. Adopted the warpage deformation as the quality index.and the five factors of processing parameters such as the molding temperature. melt temperature, filling time, packing time and packing pressure as the influence factors. CAE software was used to make the moldflow analysis of the switch panel processing parameters. and then getting its warpage results. Adopted the method of range analysis and S/N ( Signal-Noise Ratio) , optimizing the parameters and getting the optimum combination to reduce the warpage deformation. After CAE simulation of the optimum combination processing parameters. the warpage deformation is minimized. And the CAE analysis data is also proved by practical injection test.
