Automotive exterior parts are the parts system with the most plastic materials used in auto parts, mainly including bumpers, rearview mirrors, lights, door handles, air intake grilles, sunroofs, etc.
The exterior parts of modern cars are generally formed by injection molding, and then painted or textured. As a painted part, in order to ensure the consistency with the body color and paint quality, the spray system must be considered when selecting materials. For example, North American body paints mostly use high-temperature baking systems, and materials that can withstand high-temperature baking should be considered when selecting materials for exterior parts. ;As a leather-patterned piece, special consideration must be given to whether the color of the raw material and weather resistance meet the design requirements when selecting materials.
Currently commonly used exterior materials include:
PP (polypropylene)
ABS (acrylonitrile-butadiene-styrene plastic)
ASA (styrene, acrylonitrile and acrylic rubber copolymer)
POM (Polyoxymethylene)
PA (nylon, polyamide)
PC (polycarbonate)
PE (polyethylene) etc.
However, the specific materials used for each part are different. For more information on the selection and application of materials for specific parts systems, please pay attention to SHINESELL ATUO news information.
