Abstract
A method of forming a preform, for use in manufacturing a part having a predetermined part outline, includes positioning waste plastic material within an unconsolidated blank. The unconsolidated blank has an outline corresponding to a desired outline of the preform and the part outline. The method further includes selectively positioning reinforcing material within the unconsolidated blank for added strength. The unconsolidated blank is then heated and compressed to form the preform.
