사출성형품의 두께변화에 따른 마이크로 패턴의 전사율에 관한 실험적 연구
An Experimental Study on the Replication Ratio of Micro Patterns considering the Thickness Change of Injection Molded Parts
초록
Injection molding is one of the most general manufacturing processes of polymers. The deformation of final molded parts occurs because of the change of temperature and pressure during injection molding process. The deformation of injection molded parts depends on many operational conditions, such as, melt temperature, injection speed, mold temperature, packing pressure, and the structure of mold. In the present paper, injection molding experiments were performed to find the process conditions to affect the average shrinkage in thickness direction and the replication ratio of fine patterns on the surface for the final injection-molded LGP samples. As a results, in the cases of PC(Polycarbonate), when the melt temperature was under
