Automotive functional and structural parts including : engine components , heaters and air conditioning components , fuel tank and the fuel tube assemblies , lighting systems, gear plate , heater control panel , control knobs and light guide blocks , etc., must meet specific functionality.
Abroad and its alloys have been widely used in plastic automobile parts and components of various functions . Nylon is mainly used for automobile engines and engine peripheral components . Modified POM (POM) generally used in the manufacture bushings, gears , sliders and other wear parts. Modified polyphenylene oxide (PPO) in the car is mainly used for heat resistance, flame resistance, electrical properties, impact resistance, dimensional stability , high mechanical strength components. Automotive lighting system components are window glass , windshields, lights , etc., basically have plastic technology , the main material used is a PC or PMMA, etc. . Fuel tank has a single layer or multi-layer composite structure , cold , heat resistance , creep resistance, stress cracking resistance, weathering resistance, solvent resistance, chemical corrosion, etc. to meet impact resistance, leakage , fire , explosion , etc. high demands .
German BMW intake manifold made of nylon , the material is 30 to 35 % glass fiber reinforced nylon 6 or nylon 66 , compared with aluminum , plastic intake manifold can be reduced about 40% by weight , the production cost is reduced by 20 ~ 30%, while components integrated through cost can be further reduced . Bayer , BASF, DuPont , Rhodia Introduces laser welding nylon , plastic injection molding, assembled by laser welding .
