本文建立了一套智慧射出量穩定系統，結合C++程式語言以及領域知識，藉由在機台射嘴端安裝壓力感測器，即時量測射嘴端熔膠的壓力曲線並顯示於機邊電腦程式介面，有了壓力資料後便可以計算黏度因子(Viscosity Index)，透過黏度因子來分析適當的保壓切換位置。
在本文的實驗中，因保壓切換位置對於射出成品重量影響較大，故初步以保壓切換位置作為變數進行單因子實驗，並量測射出成品重量，以此來驗證黏度因子與射出成品重量之間的關係。在得知射出成品重量與黏度因子的關係後，根據塑料的P-V-T關係，以料溫作為變數進行單因子實驗，因壓力皆相同，故塑料溫度改變時，比容會隨之改變，以此驗證黏度因子會隨著塑料的比容改變而有所不同，使此系統能應用於不同的料溫。
為了能夠達成自適應控制的目的，本文也在智慧射出量穩定系統中加入自調模式，在此模式中，系統會跟機台控制器連線，並根據計算出的黏度因子回傳適當的保壓切換位置至控制器中。由實驗結果顯示，在機台參數有異常的時候，可以藉由此系統調整適當的保壓切換位置，使機台回到穩態。

To increase the productivity of injection molding machines, we developed a smart injection part weight stability control system based on C++ programming and domain knowledge. The proposed system is meant to eliminate variability in the quality of injected parts by adjusting the changeover position. We developed a viscosity index (VI) based on melt pressure data related to guide the adjustment to the changeover position in accordance with material properties. This was achieved by mounting a pressure sensor on the nozzle of the injection molding machine to enable the on-line monitoring of pressure throughout the injection molding process.
A series of experiments was conducted to characterize the relationship between VI and injection-molded samples in order to validate the efficacy of the proposed injection stability system. Single-factor experiments were conducted with the changeover position and melt temperature as parameters. The quality of the molded samples obtained under different process parameters was evaluated in terms of weight. Experiment results revealed a correlation between changes in VI and changes in the weight of the samples.
The injection stability system can also be operated in self-adjusting mode, in which the changeover position is varied according to VI. In experiments, abnormal machine operations prompted the adjustment of changeover position. Variation in the weight of parts was used to define an index by which to validate the efficacy of the proposed system.
