Abstract
In at least one embodiment, a molding method for producing a molded article is provided. The method may include introducing polymer and fiber separately into an extruder in a first ratio to produce a first extruded material having a first fiber content and in a second ratio to produce a second extruded material having a second fiber content different from the first fiber content. The method may further include filling a first region of a mold with the first extruded material and a second region of the mold with the second extruded material. The extruded material may be formed as blanks for use in compression molding or may be introduced into an injection chamber for use in injection molding. The method may be used to form molded articles having a plurality of regions having different fiber contents.
