Abstract

In this study, an injection mold is made to produce polymer line post insulators. FRP (fiber reinforced plastics) is covered by silicone housing. In injection molding process, chances for offcenter are 60 percent. Given the structure of the product, offcenter occurs owing to the imbalances in positions of gates and improper -designs of cores and jigs. This study focuses on mold modifications and improvements.
