To answer the needs concerning micro/nano molding in the field of polymer processing, we have developed a technology for 'Local Heating System'. Local heating system our company proposes differs from the conventional method where the temperature of entire metal mold is raised. Our system improves the transferability by placing the heat source extremely close to the fine pattern and actively regulating the temperature. Since it is capable of minimizing the heat mass to be thermally regulated, our system shortens the cycle time and improves productivity. A high power-density heater fabricated by a semiconductor manufacturing process was applied to a thermal imprinting device, as well as an injection molding machine, and the molding tests were done respectively. As a result, in a thermal imprinting device the system succeeded in shortening the cycle time to 1/10 with regard to the conventional system. From the measurement results of the molded samples by an injection molding with local heating system, transcription height has been found out to be 10 times higher than the conventional pattern transfer.
