正交试验法在塑件成形工艺参数优化中的作用

在未知塑件的合适工艺参数范围内,探讨正交试验法在塑件翘曲分析中优化工艺参数的效果。通过正交试验法安排试验,采用Moldflow软件进行工艺参数的优化,获得翘曲变形量。通过正交试验法获得了塑件的一组较优的工艺参数。在未知塑件的合适工艺参数范围情况下,用正交试验法寻求最佳的工艺参数并不是一个理想的方法,通过单一参数比较进行优化,在翘曲变形分析中可以取得一个最佳解。正交试验法在塑件工艺参数优化中无疑具有一定的指导作用。

Within the range of plastic parts in the unknown parameters of the appropriate technology,we explore the orthogonal experiment analysis of warpage in plastic parts to optimize the effect of process parameters.The orthogonal experiment and Moldflow software were used to optimize process parameters and obtain the amount of warping deformation and a better group of process parameters.Within the range of plastic parts in the unknown parameters of the appropriate technology,we use the orthogonal experimental method to find that the best process parameters is not an ideal way to compare a single parameter for optimization.Analysis of the warpage can be achieved in an optimal solution.Orthogonal experiment in the optimization of process parameters of plastic parts undoubtedly can have some functions in guiding.
