Injection molding electroluminescent components

Abstract

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.

Synthesis and Spectral Characterization of New Aromatic Random Copolyester

“…The temperature and heat flow scale at different cooling and heating rates were calibrated using standard materials such as indium and benzoic acid. [25] P6NPQ Ther mogram contains sharp as well as broad peaks at characteristic temperatures indicating phase transitions, before melting. The transition temperatures were calculated from the DSC thermograms and they are presented in Figure 7.…”
