NOVELTY - Method for injection molding of class A surface portion involves providing an injection mold cavity (a) for forming a geometry portion and injection mold cavity (b) with a class A mold surface for molding of a final class A surface around the geometry portion with a cavity (b), compounding a fiber reinforced polyamide with an acrylonitrile butadiene styrene material using the cavity (a) to form a portion geometry and injecting a colored polyurethane material around the portion geometry in cavity (b) for providing a class A surface coating on the portion. USE - Method for injection molding of class A surface portion for carbon fiber-reinforced thermoplastic composite used in automotive exterior component such as decklids, roof panel, composite liftgate, and hood and household application. ADVANTAGE - The method produces composite having excellent color, smoothness and esthetics.
