Injection molding is the method that makes products using melted plastic resin. Though the mass production using the injection molding we can make productivity increases. The runner system in injection molding is divided cold runner system and hot runner system. And each system have positive merits and demerits. As comparing cold runner system with hot runner system, cold runner system is more simple and cheaper then hot runner system. But hot runner system is more quality and more material efficiency. So it is important to determine the runner system considering the feature of products. We studied to select runner system, when consider economical point in injection molding.
