隨著成型品之精度要求日高，射出成型後充填階段也漸受重視，研究
的重點乃在於傳統射出與射出壓縮產品品質上的差異。主要以田口品質工
程理論來分析射出壓縮成型過程中之最適製程參數。射出壓縮成型(ICM)
，包括充填階段、保壓階段、壓縮階段、冷卻階段，乃是在傳統射出機上
加裝壓縮裝置，在後充填階段多了一壓縮步驟，本實驗並在模具前緣處設
計一封阻機構，防止熔膠逆流。 再根據田口實驗計劃法，以L12直交
表，選擇出10個控制因子，分析射出壓縮成型過程中，透過現場的實際射
出過程中，來獲得相關的數據資料，做資料的分析與預測，以便進行變異
數分析，繪製變異數分析表 ( ANOVA )，因子效果回應圖，以及各控制因
子的貢獻率；接著，做進一步的確認實驗，求算信賴區間，並證明所選取
的品質特性值具有可加性與可靠度，最後找出最佳的成型條件。

Injection molding is now used to mold precision parts such
as lenses .The quality of molding is mainly controlled by the
post-filling stage. In this thesis, a major rule based on
Taguchi Quality Engineering design, and analyzes the process in
the In Injection Compression Molding for the optimal processing
parameters, Injection Compression Molding（ICM）is on a
traditional Injection Molding machine equiped with compressional
cylinder , it increases a compressed step in post-filling stage.
This experiment designed a shut-off device front the mold.
According to Taguchi experimental design, By using L Orthogonal
Array, we choices ten governing factors to analyze the process
in the Injection Compression Molding, through the Injection
process on the spot. It can obtain the data associated with this
experiments to proceed ANOVA analysis, and draw ANOVA Array,
response graph of factor effect, and contribution rate of each
controllable factor. Finally, to find the optimal forming
condition.
