Injection molding electroluminescent components



This article explores the feasibility of using mass manufacture, namely injection molding, as a route to produce cost effective electroluminescent (EL) components straight from the mold tool. EL screen printing pastes were adapted and introduced into the injection molding environment as a multilayer structure. Four-layer systems were investigated using a spray deposition method to apply individual layer components directly in-mold. Finally, the substrate was back injected to produce a three-dimensional illuminating device straight from the mold tool. Materials, methods, and outcomes are described, the implication being that electronic manufacture could be moved upstream and performed in-mold with resultant cost and energy savings. POLYM. ENG.
