| Summary: | 碩士 === 東南科技大學 === 機械工程研究所 === 101 === Nowdays, the injection molding technology of polymers has become the primary trend of manufacturing precision 3C parts. This technology makes the performance of these products to be more powerful than ever and change life style of people.
This paper discusses the creep behavior of plain polymers in short period. By the way, flow lines affecting the creep behavior is possible.
From the creep curve and using stress review, the creep of general thermoplastic polymers is large than the one of general thermoplastic engineering polymers, and flow lines with anisotropy strength are dominant.
