摘要： A method for electro-magnetic interference shielding (EMI) of a battery box (10) or other EMI emitting device in a vehicle. The method includes the steps of forming a battery box enclosure (10) with an effective amount of a shielding material (20) attached to the enclosure (10). In one embodiment the box (10) is an SMC or injection molded preformed enclosure (10), and a metallic material (20) is attached to the enclosure (10) on an interior or exterior side of the enclosure (10). In another embodiment the enclosure (10) and mesh (20) are formed in the same mold cavity (24) for embedding the shielding material (20) in the enclosure (10).

摘要： A method of injection molding of a class A surface part comprising the steps of first providing a first injections mold cavity for forming a part geometry and a second injection mold cavity for molding of a final class A surface around the part geometry with a second material. Then a fiber reinforced polyamide with an effective amount of an ABS material is compounded and the first injection mold cavity is used to form a part geometry. Thereafter, a colored polyurethane material is injected around the part geometry in the second injection molded cavity for providing a class A surface coating on the part.
