射出成型是一種具有高產量、低成本與可自動化的塑膠成型技術,然而塑料受到不同溫度、壓力、流速與密度的變化,使產品的品質具有高度的非線性。因此,本研究主要目的是建立鏡片之最佳輪廓精度的射出成型參數之操作視窗,藉由操作視窗的產品之輪廓精度需求,選擇出符合品質且最低成本的操作條件。首先,以田口實驗設計找出最佳的製程參數,之後經由變異數之貢獻率大小選擇出控制因子,進行全因子實驗找出合適的迴歸模型及建立反應曲面,再以中央合成設計逐步尋找最小之輪廓精度範圍,然後統合所有之實驗點建立操作視窗,最後進行驗證實驗,以驗證操作視窗之準確性。
Injection molding of plastic products is a low-cost, high production-rate processing technology which is suitable for automation; however, the quality of the product is highly nonlinear because of the variations in temperature, pressure, flow-rate and density of the materials. This study is aimed at identifying the operation windows for the injection molding process parameters which produce lenses with optimized contour precision. The operation conditions for products with qualified contour precision and the lowest cost can be determined through these operation parameter windows. Taguchi experimental method was used to determine the optimized set of process parameters, and the control factors were identified through the contribution of the variance for each parameter. Full factorial experiments were implemented to identify the appropriate regression model to construct response surface, and the central composite design (CCD) was used to progressively determine the range of process parameters for lenses with minimum form error. The data points of the experiments were constructed the operation parameter windows, and confirmation experiments were performed to verify the validity of the windows.
