    Influence of molding conditions on the shrinkage and roundness of injection molded parts
    (SPRINGER LONDON LTD, 2010) BAKIR, BARKIN; Kurt, Mustafa; Kaynak, Yusuf; Kamber, Omer S.; Mutlu, Bilcen; Bakir, Barkin; Koklu, Ugur
    During the plastic injection molding process, one of the biggest challenges is shrinkage which deteriorates the quality of produced parts. To control and reduce this defect, the essential way is to perfectly determine the variables like molding parameters. In this study, the effects of molding parameters including packing pressure, melt temperature, and cooling time on shrinkage and roundness have been investigated experimentally. Also, the relationship among initial molding parameters, the cavity pressure, and mold temperature was investigated. The results of this experimental study and analysis fulfill various requirements of plastic injection molding and clarify the relationship between molding conditions and the overall quality of produced parts. This study illustrated that packing pressure and melt temperature are dominant factors which determine the quality of parts.
