基于CAE技术的注塑件翘曲变形分析

Based on CAE Technology to Analyze Injection Molding Warp

注塑成型是批量生产塑料制品的首选方法。但如何减少、防止制品成形中时常发生的翘曲现象,是经常困扰工程师的一大难题。有时仅仅依靠传统的经验、技术诀窍和不断试模的方法,仍不能有效地解决问题。因此,将CAE技术应用于注塑成型,进行翘曲变形预测,优化注塑成型工艺参数设置,从而提高生产效率和成型质量,是解决翘曲变形问题的新思路。

Injection molding is a produce the plastic products in batch. But it is a great perplexing problem to reduce and prevent the warping phenomenon during injection molding. The problem can＇t be solved effectively by experience, technical knack or repetitious test. Therefore, a new thought has been put forward that we can apply the CAE technology in this field. By CAE we can forecast the warping to optimize the parameter of injection molding. Then, the producing efficiency and the quality of the plastic products will be improved correspondingly.
