초록

Today, looking at the trend of product development, interests of injection technology to reduce weldline are growing because of increases of polymer composite materials that containing functional elements and demand of no-painted injection in accordance with environmental regulations. In this paper, surface temperatures of mold increased using high temperature gas for elimination of weldline and characteristics of weldline are analyzed according to mold temperature($60^{\circ}C{\sim}120^{\circ}C$).
