Performance characteristics of automotive plastic parts

　　 (1) Light weight
　　 One of the outstanding advantages of polymer automotive materials is that it has the characteristics of light weight and high strength. Since the average proportion of various plastics is only 15-20% of ordinary steel, it is also lighter than ordinary wood. This feature has outstanding advantages especially for large cars, which can reduce a large amount of self-weight.
　　 (2) Excellent comprehensive physical and chemical properties
　　 Another advantage of polymer automotive materials is that they have multiple functions and can be used in special occasions. Plastics have good insulation properties, excellent corrosion resistance, aging resistance, good wear and scrub resistance, good waterproof and mechanical properties, and good bonding and bonding properties. They are processed into various A variety of automotive interior and exterior trim parts that require multiple performances and functions.
(3) Excellent decorative effect
　　 The outstanding advantage of polymer automotive materials is the decorative effect. It can be processed into products with complex shapes and multiple colors at one time. Sometimes it needs to be printed, pasted, embossed, laminated, and colored to be processed into a very realistic image, pattern and pattern, which can imitate natural wood, metal, The texture of animal skin can also be gilded, filmed, silver-plated, inlaid, etc. on the surface.
　　 (4) Good processing performance
Due to the plasticity of polymer automotive materials and the good compatibility with other materials, different material components can be used, with the help of various modern molding and processing machinery, through extrusion, injection molding, calendering, molding, and blow molding. Processed into polymer automotive materials with various shapes, different properties, different colors, and different functions, such as directly extruded into tubes, profiles, plates, injection into products with various shapes, and calendered into films, etc. It can also be made into various colors, sandwiches, hollows, inserts and other products according to needs. It can also be subjected to secondary processing according to requirements, such as turning, punching, cutting, welding, and hot-melting of mechanical products. , Cold sawing, compounding, etc.
