Orthogonal Design Optimized Experiment of Polyimide Composite Injection Molding Process

提出应用注射成型工艺方法,通过正交试验优化设计开展了工艺参数优化试验,研究了各注塑工艺参数对于最终成品质量的影响,找到了最优的工艺参数,并通过生产试验,成功减小了零件翘曲变形量,实现了产品的直接注塑成型,提高了生产效率和成品率。

Based on the characteristics of polyimide composite, thermoplastic molding process has been applied. Orthogonal experiment design method has been used to optimize the parameters of injection. In order to reduce the warping of the part, five independent parameters have been studied, and the optimized parameters have been received. With the result of experimentation, a production test has been put on. Finally, the warping deformation amount has been decreased, and other sizes of the part are produced directly by molding injection. The production efficiency and rate of final products have been increased.
