Overmolding vacuum cast parts
O
hello! I’m working on a project that involves overmolding for a VC (valve cover) application. The goal is to embed connectors and screws directly into the molded part to streamline assembly and improve durability. I’m curious about the feasibility of this approach: does overmolding provide a secure enough bond to reliably hold metal inserts like connectors and screws under thermal cycling and vibration stresses typical for automotive applications?
