隨著時代的進步，現代人對3C產品的要求越來越高，然而傳統的定模溫製程受限於溫度，在製作上有所難度，因此，變模溫製程成為解決這類問題的最佳方法。目前的變模溫製程方法相當多：如薄膜加熱，蒸氣加熱，油加熱，紅外線加熱等方法。

本論文模擬方式是以ANSYS做電磁感應加熱分析，模擬時將線圈和模板根據實際加熱情況作建模，並觀察其模擬結果與實驗結果是否相似。
本論文實驗方式採用二種多匝線圈進行感應加熱測試，依序為跑道形線圈和螺旋形線圈。模板尺寸為150*150*10(mm)，同時附帶11個5*5*150(mm)之溝槽。以螺旋形線圈和模版距離30mm為例，模擬結果顯示加熱速率為1.23℃/s，而實驗結果為2.87℃/s，其差異相當大，可能原因為模擬時材料參數資訊不足造成溫度上的差異，然而在溫度分布上，兩者的結果相似。
將模擬與實驗數據作紀錄，同時作為日後線圈設計的依據。

To increase the quality of 3C products, the mold temperature during injection molding needs to be precisely controlled. But the traditional manufacture is limited by constant mold temperature and it wouldn’t satisfy our demand. So the traditional injection molding process needs to be shifted to the variotherm system. So far, there exists many different approaches of variotherm system, for instance: thin film heating, steam heating, hot oil heating or infrared heating.
In this thesis, ANSYS software was used for the electromagnetic induction heating simulation. The simulation results of temperature value comparing to the experimental ones were different, while the temperature distribution were the same. Due to the lack of information of the mold material, the difference in temperature value were expected.
In the experiments, two different kinds of heating coil were investigated: elliptical coil and helical coil. The coil was placed behind the plate and heated the plate from different distances. An Infrared Camera was used to observe the surface temperature. These simulation and experiment data would be helpful for future design of rapid mold heating system with electromagnetic induction technique.
