由於射出成型量產迅速與低成本生產的兩大優勢，使其成為製造業
中重要的量產技術。近年來，許多產品具有微特徵、薄型工件等特
點，且對於產品的表面品質也非常要求，但此類產品在射出成型時
常碰到許多問題，如微特徵的轉寫性不佳、流痕、表面品質不佳等
。為解決生產此類產品所碰到的困難，提高模具溫度為經常被採用
的解決方法，因此提升模溫的相關方法陸續發展，其中電磁感應加
熱方式因有加熱迅速、能源消耗少、降低環境污染等優勢，使其成
為主要用以提升模溫的媒介。過去應用感應加熱於提升模溫的研究
，未有溫度均勻性相關的研究，且存在因外部加熱而使成型周期增
加的問題，因此本研究將發展均勻模面加熱的嵌入式感應加熱單元
以改善這些問題。透過柵欄式感應線圈與磁場集中器的運用，經由
測試實驗已知可使厚度為7mm 的熱作模具鋼(JIS SKD61)其模面溫
度於15 秒內由50oC 上升至150oC，並達到94%~95%左右的均勻
性。而本研究也已運用柵欄式線圈與磁場集中器來製作感應加熱裝
置，並成功發展出嵌入式感應加熱單元，此加熱單元針對母模板的
目標區域進行加熱後，該目標區域的溫度均勻性可高達94%~96%
，而加熱速率可達3.5oC/sec 左右。

Injection molding is one of the major fabrication
technologies, andmany manufacturers used it to fabricate
products. In recent years,many products have the
requirements including high surface quality,high gloss and
high replication. And rising tool surface temperature is
one of the solutions for the ones. So, many tool surface heatingtechniques have been developed recently. Due to the
advantages ofelectromagnetic induction heating such as high speed heating, lowenergy consumption and environmental pollution reduction, using theone for tool surface heating is more significant among those tool surface heating techniques.In the past, the studies of using electromagnetic induction heating for tool surface heating indicated that the temperature uniformity and
increasing cycle time were questionable until now. In this thesis, the insert type induction heating module will be developed to improve those problems. According to the result of coil test experiments, the surface temperature of 7mm thickness hot work die steel (JIS SKD61) could rise from 50oC to 150oC in 15 seconds and the temperature
uniformity of heated zone reached 94%~95%.In this thesis, the parallel type coil and magnetic flux concentrators were adopted to fabricated induction heating apparatus.
And the insert type induction heating module was developed
successfully. This induction heating module could heat the target area of mold cavity uniformly. The uniformity of target area reached 94%~96%. And the heating rate of this module is about 3.5oC/sec
