      다국어 초록 (Multilingual Abstract)

      Plastic injection molding is the way of molding products by freezing in a mold with pressurization and injection. At that time, the quality of plastic product wasn’t important, but nowadays, it is required that the magnificence of appearance and mechanical strength of product are on the basis of plastic products. It is required to minimize some flaws, such as weldline, flow mark, sink mark, void, jetting, air trap, in order to improve the quality of products.
      Weldline, one of the poor maintenance, is recognized very serious problem, in case of combining between a separated flow front on the appearance of product, that is reason of deterioration, relating to quality and magnitude. If there are some holes in the process of molding, weld lines are formed, which brings about more mechanical and structured deterioration.
      In general, the quality of injection molding is decided by multi-dimensional design space, such as material, mold, part, process conditions. So, we have to control all variables in order to make a high-quality injection molding, and it depends on a optimum design. This research is objective to minimize Weldline, one of the deterioration, and contributes to improve the quality of completed products, brand image of domestic motor corporations.
