针对某遥控器前壳在双色注塑成型过程中的翘曲变形对装配质量及产品整体外观的影响，提出了基于正交试验和AMI数值模拟的双色塑件翘曲变形快速优化方法。利用AMI有限元分析软件对遥控器前壳进行双色注射成型数值模拟，采用多因素交互正交试验的方法获得两种材料在不同工艺参数组合下的翘曲变形量，以翘曲变形量最大值最小为研究目标，对试验结果进行极差和方差分析，从而确定不同工艺参数对试验结果影响的重要性，并最终确定了产品翘曲变形最小的最优工艺参数组合。结果表明该优化方法可以快速优化双色塑件在成型过程中的翘曲变形量。

Optimization of Warping Deformation of Remote Double Color Front Shell Based on Orthogonal Test

Double color plastic warping deformation quick optimization method was proposed based on orthogonal test and AMI numerical simulation according to the influence of warping deformation on assembly quality and product overall appearance in the process of double color injection molding of remote shell. Double color injection molding simulation of remote control front shell was carried out by AMI finite element analysis software and warping deformation of materials under different process parameters was obtained by multi factor orthogonal experiment. Taking the minimum value of warping deformation maximum as research target, test results data were analyzed by range and variance, influence of different process parameters on the test results was determined, and the optimal process parameters combination of product warping deformation minimum was finally determined. Research results show that the optimization method can quickly optimize the warpage of double color plastic in the injection molding process.
