基于Moldflow的塑件注塑成型参数优化

文章借助Moldflow软件对多筋类塑件进行初始方案模流分析，发现了塑件翘曲变形过大的缺陷。通过调整注塑 参数再次进行模流分析并与初始方案进行了对比，发现改善方案能有效解决制品翘曲变形量较大的问题，成功优化了注 塑成型工艺参数。实践证明，借助Moldflow的模流分析，可估定塑件成型时各个加工参数的合理值变动区域，减少试模 次数，设定最佳的模具注塑方案，获得质量更优的塑料制件。

Optimization of Multi-ribs Plastic Injection Molding Parameters Based on Moldflow

Optimization of injection molding parameters for multi-ribs plastic part by Moldflow software was studied. The defect of excessive warpage in plastic part was discovered through the mold flow analysis of an initial program. Then the mold flow was analyzed again by adjusting the injection parameters. Comparing it with initial program, it was found that the problem of large amount of warpage was effectively solved by the improved program, and the injection molding parameters were optimized successfully. Practice has proved that Moldflow analysis could assess processing parameters and provide a variation zone. as a result could reduce modeling times, setup the best program of injection mold was devised and obtain better quality plastic parts.
