A system for manufacturing a trim panel includes a plurality of rollers for routing a foam core of the trim panel along a path. A first doctor blade for applying an adhesive resin is disposed adjacent to the first side of the foam core. A second doctor blade for applying an adhesive resin to the second side of the foam core is disposed adjacent the second side of the foam core. The system further includes a mixing head having an output port. A mixing tube is attached to the output port. The mixing head defines first, second, and third distinct fluid paths for the first, second and third components, respectively. The first, second, and third fluid ports extend to the output port. In use, the system continuously monitors the actual application rate of the adhesive resin and compares this actual application rate to a desired application rate and adjusts the pump output accordingly.
