摘要

在一項新產品之研發階段中，縮短研發時間與減少投資成本是一個重要議題。本研究旨在運用再生金屬樹脂研製具工業實用價值之快速模具，並針對不同型號之環氧樹脂，調配不同粒徑再生金屬樹脂粉末之試片，進行壓縮強度研究。研究結果發現使用174 AB型號環氧樹脂、粒徑0.02 mm再生金屬樹脂粉末、再生金屬樹脂粉末與環氧樹脂以1：0.5重量混合比例以及烘烤溫度為45℃，所製作之金屬樹脂模具具有優良機械性質，運用本研究所研製之再生金屬樹脂壓縮強度約可以達到市售金屬樹脂環氧樹脂壓縮強度的95%。以熱印印模具長、寬、高尺寸分別為70 mm、70 mm及15 mm為例，如與傳統方法進行比較，運用本研究所提出方法，可以節省模具總製作成本約為26.6%，以及節省最後一道製作成本約為50.4%。

Reducing the time and investment cost in the research and development phase of a new product is an important issue. The objective of this study is to develop a rapid tooling with industrial application value using recycled Al-filled epoxy resins. The compressive strength of the samples fabricated by the mixture of different kinds of epoxy resins and different particle sizes of recycled Al-filled epoxy resin powders were investigated experimentally. It was found that the 174 AB epoxy resins seem to be a good candidate for mixing recycled Al-filled epoxy resin powders. The 1:0.5 is the optimal mixing ratio for mixing epoxy resin and recycled Al-filled epoxy resin powders. The 45℃ is the optimal temperature for heating test samples. The average particle size of 0.02 mm is the optimal recycled powder size. The compressive strength of the test sample fabricated by the optimal parameters is 95% of that fabricated fully by commercial materials. For the hot embossing stamp with dimensions of 70 mm in length, 70 mm in width, and 15 mm in height, the total manufacturing cost savings about 26.6% and the last process manufacturing cost savings about 50.4 % can be obtained using the method proposed in this work.
