近年來，由於射出成型具有成產迅速以及低成本的優點，使其成為製造業中重要的量產技術。而在射出成型製程時會遇到流痕、縫合線等問題，故提高模具溫度為經常被採用的解決方法，因此模具快速加熱技術在工業界的應用愈來愈廣，目前模具的加熱方式有油加熱、紅外線加熱等方法，其中電磁感應加熱技術具有可精準控溫、加熱迅速、減少生產週期、能源損耗少以及低污染等優點，故本論文將對此方法進行探討。
本研究中將已開發的嵌入式感應加熱測試模具實際接上水路進行測試，透過柵欄式感應線圈的設計，再經由測試實驗已知可使模面加熱速率達到3℃/sec左右，而在針對局部加熱過程中的溫度均勻性可達到91%以上。
本研究中亦探討電磁感應加熱原理應用在熱澆道系統上，透過線圈的設計，針對圓柱型熱澆道進行測試實驗，以了解此設計是否可以改善溫度均勻性的問題，而實驗結果可得知在經由線圈設計上的改變，加熱速率可達到3.4℃/sec，在均勻性方面可提升至溫差10℃以內。
將本論文所得之結果作紀錄，未來可做更複雜的線圈設計，並實際應用在射出成型上。

Injection molding has become one of the major fabrication technologies in recent years, and many manufacturers used it to fabricate products. However, in the injection molding process will encounter some problem such as flow mark and welding line. Therefore, rising tool surface temperature is one of the solutions for the problem and the mold rapid heating technology has been adopted more widely by industries. So far, there are many methods of mold heating, such as hot oil heating and infrared heating. Due to the advantages of electromagnetic induction heating which is precise temperature control, high speed heating, reduce the production cycle, low energy consumption and environmental pollution reduction. Therefore, this study will discuss the method.
In this thesis, the insert type induction heating module connected to the cooling channel will be tested by experiments. According to the result of experiments, the mold surface heating rate reached about 3℃/sec and the uniformity of temperature for heated zone was higher than 91%.
In this study, principle of electromagnetic induction heating of hot runner systems was applied. According to the result of experiments, the heating rate reached about 3.4℃/sec and the uniformity of temperature can be raised to near 10℃ of the coil design changes.
