ABSTRACT:
An automated transfer/injection molding apparatus and process is defined that includes a charge forming unit, a shuttle unit, and a molding unit. The charge is formed from one or more slabs of reinforcing fibers and a resinous material. Once formed, the charge is preheated in the charge shuttle unit and is delivered to the molding unit, whereupon the preheated charges are forced by the pressure of a movable platform under vacuum into a mold cavity for polymerization. The fibers within the slabs are randomly oriented in parallel horizontal planes such that they are always parallel to the direction of initial flow into the cavity.
