摘要

矽膠是一種非常好的快速模具材料，主要的原因為運用矽膠所製作之矽膠模，具有優良的尺寸穩定性。為了提升矽膠模具製作效率，如何精確量測矽膠硬化時間即變成一個重要議題。因此，本研究建構一套非破壞性矽膠硬化時間之量測系統。以人工量測結果為基準，並根據穿透功率變化以及矽膠溫度變化，提出矽膠硬化時間鑑定準則。建立矽膠硬化時間之預測方程式，並探討預測方程式之誤差率，最後提出一個矽膠硬化之完整過程。

Silicone rubber is an accurate rapid tooling material based on dimensional stability. To enhance the efficiency of making the silicone rubber mold, accurately measuring the solidification time is an important issue. This study demonstrated a non-destructive measurement system to determine the solidification time of silicone rubber. The criterion for determining the solidification time of silicone rubber was proposed according to the changes both in the transmitted power and temperature obtained. The predicted equation for predicting the solidification time of silicone rubber mold was proposed. The applicability of the solidification time using the predicted equation was investigated and compared with manual measurement. The relative error of the predicted equation was also investigated. The entire solidification processes of silicone rubber mold were finally demonstrated.
