摘要

運用金屬樹脂所製作之熱壓印模具可以運用於少量生產，但是與金屬熱壓印模具比較，成型週期時間比較長，主要的原因為運用金屬樹脂所製作之熱壓印模具其熱傳導率不佳。因此，研製高冷卻效率之熱壓印快速模具是一個重要研究方向。本研究製作三副不同冷卻水路之熱壓印快速模具，並研究三副熱壓印模具於熱壓印過程中之冷卻時間，研究結果發現，如與熱壓印快速模具不具冷卻水路進行比較，當熱壓印快速模具具有順形冷卻水路，可以節省冷卻時間約92%。

Hot embossing stamp fabricated by aluminum-filled epoxy resin can be employed for low volume productions. However, due to poor thermal conductivity, its process cycle time is much longer than metallic stamps. Therefore, developing hot embossing stamps with high cooling efficiency is an important issue. In this study, three different kinds of hot embossing stamps with or without cooling channels were fabricated using rapid prototyping and rapid tooling techniques. Effects of different hot embossing stamps on the cooling time during hot embossing molding were investigated. It was noted that the cooling time of using a hot embossing stamp with conformal cooling channels can be reduced by about 92% with respect to those without cooling channels.
