Plastic injection molding is a manufacturing process of heating plastic granules and forcing melted plastic into a mold cavity and removing from the mold after cooling. One of the most important elements in the production of parts by plastic injection molding is the analysis of the plastic injection mold design and the part to be produced. The effect of cooling system, that is designed in the mold production, on the product quality is very important in the plastic injection molding process. The mostly faced product faults caused by the improper design of the cooling system are sink marks, burns, air and
gas bubbles formation, warpage, burrs, schrinkage and whitening. For this reason, the design of the cooling systems is one of the most important factor in plastic injection molding process. The cooling system design has the greatest prospect among the factors that affect cycle time in production. Reduction of the cycle time is one of the parameters that should be emphasized in mold design in terms of both economy, efficiency and quality. In this study, a cooling system analysis was performed on the mold design of a 16-cell pet bottle cover designed to be produced by plastic injection molding. The cooling system analysis of the design is carried by the software MoldFlow and based on the data obtained by the MoldFlow program design improvement studies are performed and the design is therefore optimized.
