| Research Abstract |
Various approaches to solve the problem of molding defects like the warpage, the short-shot, and the burn marks have been investigated. In order to observe transition phenomena in the polymer injection, determination of outgas composition and visualization of inside situation in injection process were carried out in this work. In addition, rationalized gas monitoring method by utilizing sensor device was also examined to realize real time monitoring at the actual shot. It was successfully obtained that key chemical reactions in regard with appearance of burn mark by taking consideration into conditions which influenced the composition change of outgas. Finally basic knowledge to suppress molding defects was also discussed.
