Effect of gate number on the warpage in injection molding

Abstract

Injection molding of the typical thin-walled parts, named back door of car, has been systematically investigated. We have focused on the relationship between gate number and warpage in the injection molding process, by designing inject and cooling systems and tailoring the processing parameters based on the simulated analysis of MOLDFLOE software. The optimized processing parameters have been achieved by the compared investigation of the warpage with different gates. Finally, some manners have been proposed to reduce the warpage of the thin-walled parts. © 2012 Springer-Verlag GmbH.
