Abstract
An apparatus and method for manufacturing plural component materials, especially rigid urethane structures, from reactive components. The system includes a source of a first component, a source of a second component, a sprayer for mixing the components and for dispensing the mixture therefrom, and a delivery system for delivering the components to the sprayer. The delivery system is designed to continuously recirculate the components from their respective sources to the sprayer and back to the sources and includes positive displacement piston pumps simultaneously driven by a single motor. The system further includes means for calibrating the rates of flow of the components in the delivery system and a chopper to direct reinforcing glass fibers into the component mixture dispensed from the sprayer.
