A fiber-orientation system for a fiber-reinforced thermoplastic is provided. In various embodiments, the system includes a first tool, and a second tool that, in combination with the first tool, defines a gap therebetween configured to define a flow path for a fiber-reinforced thermoplastic melt during an injection molding. A plurality of electrodes are disposed in the first tool. The electrodes have exposed ends disposed in or along the flow path such that the electrodes are configured to, when energized, orient fibers within the thermoplastic melt. This provides a localized, controllable modification of the orientation of the fibers within the melt.
