The invention relates to a method for producing a natural fiber-reinforced plastic part, wherein as the starting material natural fibers 5-120 mm in length, a thermoplastic and/or a duroplastic and a lubricant, especially wax, are pelletized without extrusion into long-fiber pellets by cold-forming and the long-fiber pellets are then feed for direct processing into a standard injection molding machine for injecting the plastic part.
