Engineering Guide: Solving Overmolding & Insert Displacement Pain Points for EV Fasteners
Overmolded fasteners, structural brackets, and insulated busbar tighteners are backbone components in NEV battery packs and chassis assemblies. Insert molding—the process of encapsulating metal fasteners within high-performance engineering plastics (such as PBT-GF30 or PPS)—offers excellent weight savings and electrical insulation. However, joining two vastly different materials (metal and plastic) creates unique manufacturing headaches. Below is…
