The effects of injection parameters and foaming agent on dimensional accuracy of produced parts in plastic injection molding

Abstract

Dimensional accuracy is an important factor for all components manufactured by plastic injection molding. This factor is more significant for functional components loaded in dynamic manner. In this study, rotatory roller of cleaning robot were produced with plastic injection molding process and the effects of temperature, pressure, cooling time, and foaming agent on dimensional accuracy of investigated pieces. Experimental findings show that measured input variables have some effect on measured outputs. Besides, this study shows that using foaming agent contributes to controlling dimensional accuracy of this component.
