Abstract
The application range of injection molded parts is expanding by the development of engineering plastics with good mechanical properties. Plastic products are specially used as automotive parts due to an excellent performance in the characteristics of a strength vs. weight. In this study, heating type of new method such as jet injection was applied to improve heat transfer coefficient is substituted for heating method of injection molding.
