| 摘要: | 塑膠材料具有密度低且成型能力佳的優點，一般皆使用射出成型製程進行
塑膠產品的製作。射出成型製程的塑膠產品易產生不均勻收縮、殘餘應力與變形
翹曲等缺陷，其中產品翹曲變形的缺陷將造成精度或組裝上的問題；由於射出製
程參數的設定與射出成品的翹曲變形影響甚大，因此翹曲變形的探討為射出成型
製程中重要課題之一。本論文以杯墊的射出成型製程為研究對象，使用模流分析
軟體Moldex3D 並搭配反應曲面法進行分析，探討射出成型製程參數對翹曲變形
的影響，進而求得最小翹曲量的最佳射出成型製程參數；並使用二次元光學測驗
儀量測接合區域翹曲量進行最佳製程參數驗證。本論文利用模流分析軟體模擬塑
膠射出過程與結果，改善傳統射出製程須不斷修改模具及加工條件等缺點，不但
有效提升射出成型的品質，並可大幅降低生產成本與開發時間。
The advantages of plastics are quick production and lower density. The plastic
products are generally produced using the injection molding process. The defects of
unbalance shrinkage, residual stress and warpage will be caused in injection molding
parts. The warpage affects the precision and assembly of molded parts among these
defects. The level of warpage is highly related to the injection machine parameters
setting. Therefore, the exploration of warpage is an important issue for the injection
molding process. This study performs the analysis of coaster which is prepared by
injection molding using Moldex3D software and Response Surface Methodology. The
effect of injection machine parameters setting on the warpage was discussed.
Furthermore, the optimal injection machine parameters were determined for
minimizing the warpage in injection molding. To verify the accuracy of the optimal
injection machine parameters, this study measures the warpage using Vision
Measuring Machine. The simulated results obtained here can be useful for improving
the disadvantages of trials and modification of mold on a traditional process.
Moreover, this work not only improves the quality of molded parts, but also reduces
the time and cost in the development stage. |
