Automotive plastic parts, that is, automotive products made of plastic accessories. Plastic parts in the car on a wide range of applications, including body and interior parts are common, but also to the most interior parts.

Performance characteristics of automotive plastic parts
1, the advantages of automotive plastic parts
(1), light weight
Polymer material is one of the most prominent advantages of light and high strength properties. Because the average proportion of all kinds of plastic only ordinary steel 15-20%, lighter than the average timber. This feature on the high-end large-scale cars in particular have outstanding advantages, can be deducted from a large number of self-respect.
(2), excellent comprehensive physical and chemical properties
Another advantage of polymer materials is that they have a variety of functions and can be used in special applications. Plastic has good insulation properties, excellent corrosion resistance, anti-aging properties, good wear resistance and scrubbing performance, good water resistance and mechanical properties, good bonding with the performance, is processed into various processed into each A variety of performance and functionality requirements of automotive interior and exterior trim.
(3), excellent decorative effect
Polymer materials, the most prominent advantage is excellent decorative effect. It can be processed into a complex shape and a variety of colors of the products, and sometimes need to print, film, ginning, complex layer, coloring, processed into a very realistic image, patterns and patterns, can imitate natural wood, Animal skin texture, but also the surface of gold foil, foil, silver, mosaic and so on.
(4), good processing performance
Due to the plasticity of polymer materials and good compatibility with other materials, it is possible to use different materials and components by means of a variety of modern molding machines, by extrusion, injection molding, calendering, molding, blow molding Such as direct extrusion into pipes, profiles, plates, injection into a variety of shapes of products, rolling into a thin film processing, and so on, with a variety of different shapes, different properties, different colors, different functions of polymer car materials, Can also be made according to the needs of various colors, sandwich, hollow, put inserts and other products, but also on the request of the secondary processing, such as mechanical products like turning, punching, cutting, welding, , Cold saw, composite and so on.
2, shortcomings
(1), poor heat resistance:
High temperature performance is poor polymer macromolecule materials, another major drawback. Most of the thermoplastic polymer materials, the operating temperature of 80 degrees Celsius below the temperature often occurs above the thermal deformation, so that polymer materials can not maintain the original shape and structure, performance will also change greatly.
(2), poor rigidity:
Polymer building materials have good plasticity, but its rigidity is poor, it can not be used for the requirements of a larger bearing capacity of the place or as the main force structure, or because of insufficient stiffness caused by instability and other damage ; In addition, its anti-deformation capacity is not as natural materials processing of traditional materials.
(3), with combustibility:
Another drawback of plastics is its combustibility compared to steel. Plastic can be divided into two categories, one is not burning, the other is combustible.
