사출성형을 이용한 마이크로 도광판의 성형에 관한 연구

다국어 초록 (Multilingual Abstract)

The Injection molding process has a high accuracy, good reproducibility in high numbers and at lows cost. However, it has been known that it is hard to understand the size limitation and requirement for a very highly pressure and various parameters. In order to overcome these problems, we developed an injection molding system for production of micro-LGP(Light Guide Plate) and carried out various experiments with respect to injection pressure, molding temperature, back pressure, and molding time etc. And also, in order to overcome molding defects such as flow marks, non-fill, and sticking etc., the peltier elements for stable control of molding temperature was used. Through various experiments and analyses, the performance and validity of our injection molding system confirmed. Finally, we compared results and parameters of an injection molding system with those of a hot embossing system. Consequently, we proved that, compared with a hot embossing process, an injection molding process will likely have a better performance, cost-effectiveness and yield.
