Development of Induction Heating and Cooling Injection Mold Equipped with Melt Flow Control System

Abstract

Weld-lines, a molding defect in plastic injection molding, not only cause disfigurement of the exterior of molded products, but only reduce their mechanical strength. In this report, induction heating and cooling injection mold equipped with melt flow control system using a movable core pin newly was designed and manufactured. Then, we confirmed that the use of this mold could lead to an improvement in the exterior and an increase in the bending strength of glass fiber reinforced polypropylene molded product.
