Among the factors affecting the quality of injection molding plastic parts, We studied the effects of mold surface heating method on the transcription of injection molding plastic parts with nano structures. We developed the stamper structured mold with moving heating core type with nano pattern. Mold surface heating has been tested by three different methods. The first was conventional injection molding process without heating moving core, the second was halogen lamp radiation heating process and the last was MmSH process using gas flame. As a result of making injection molding plastic parts by using thermoplastic amorphous resins such as COC, MmSH method showed the best nano pattern transcription of the three methods, but the outcome of conventional injection molding process was not better than others.
