Shanghai Daoqin Plastics Co., Ltd.

        现代生 active in less automotive 身影, is 人们 出行 provide large 便利, automotive industry development industry chain day formed 熟, and 由此衍生出 一 series automotive related industry obtain large development. automotive inner outer field/area in recent years separation active 跃, many new material, new technology application make industry field/area 也焕发出 new machine.

         automotive outer design key points

         if automotive inner is is provide 舒适 乘驾体验, that automotive outer is is make more meanwhile 保障乘驾 safety. due to automotive function, therefore automotive outer trim parts must 坚持“三化” design 原则, standards 化, series 化, general purpose 化, meanwhile need meet/satisfy combined property, can property, type, property, repair property, manufacturing process property “六 property requirements ”.

         according to type 投放 国家 区 different, design process must comprehensive 贯彻执行当 regulations standards. main/primary front rear 保险杠牌照安装孔孔间距 dimensions 规定, is need 预留雾灯安装孔, tool 安装, external material requirements and dimensions and other related requirements, has dispersion hot device 面罩迎风面积 is meet/satisfy machine, made cold requirements, need related 部门 认 can.

         in addition in automotive outer several upper, for material requirements has 差异. rear 视镜, 格栅, lamp covers and other 车身部位 组 parts, need has relatively good heat resistant property, resistant scratch property, lightfast property, chemical resistant property and other;行李架, 车位以, welding strip/profile and other year cationic 直射部位 need has relatively good heat resistant property, low temperature resistance property, lightfast property, chemical resistant property;轮毂, 保险杠 and other 底盘附近部位则 more need has good rigid property, resistant scratch property, low temperature resistance impact property, resistant impact property and other.

         plastics types type and automotive outer 饰

         currently automotive upper use plastics generally is PP(polypropylene (PP)), PE(polyethylene (PE)), ABS(polyurethane ester), PMMA(polyether ether ketone), PA(nylon), PC(polycarbonate (PC)) and other. environmental protection strong/high and 科研人员 for new material 探索, new type plastics and use 也逐渐 expand large to automotive outer field/area. 如秸秆, 亚麻, 甜菜, housing/shell and other material in fiber 素, can made formed bio-based plastics application in automotive field/area.

         although in 一 特殊部 parts upper, bio-based plastics strong/high degree issues still is made its large use factors, is in automotive outer field/area already has formed 功案例. front Netherlands 打造 “ bio-based ” light type electric vehicles in use types material. not only make related parts tool has glass fiber strong/high degree weight ratio, 且车体 weight to large decrease light.

         plastics in automotive outer upper application

         plastics processing properties and use property can relatively is 理想, and and automotive manufacturing in use metal versus ratio, more low cost, more light weight 也顺应 automotive light amount trend, therefore 越 越 more plastics automotive parts substitute/replace metal. Common automotive outer trim parts has front rear 保险杠, rear 视镜, 行李架, 格栅, 轮毂, and its parts, 车门 手组 parts, dispersion hot device decoration 罩, anti 撞梁, anti scratch strip/profile, device and other.

        我们举例 several Common plastics in automotive outer upper application:

        1, 保险杠: front 保险杠 and rear 保险杠. 保险杠 can absorption in 车辆发生碰撞时 generate can amount, decrease/reduce for 车身部 parts and 乘车人员 伤害. need tool has good impact resistant property, weather resistance, paint force and other property can, polyester 系, polypropylene (PP) composite/compounding material and TPO in plastics 保险杠 in relatively is Common.

        2, rear 视镜: due to its long day 晒雨淋 and other gas and 行驶颠簸 and other factors effect/influence, rear 视镜材 material need tool has weather resistance. in to temperature degree, wet degree, strong/high degree, impact and bending property can and other requirements, meanwhile also need material easy aging, corrosion resistant, injection molding property can and property can good and other and other. material generally can using/adopting heat resistant ABS, PC, ASA, PBT+GF and other.

        3, 行李架: ensure in various complex force use lower 行李架不受破 bad, requirements material has fatigue strong/high degree, ensure in automotive fast speed and 紧急刹车时, 行李架不致 has heavy fatigue loss 伤. generally can using/adopting PC/PBT, PC/ASA, PC/ABS, ASA and other material.

        4, 车灯: can separation is front 照灯, rear 车灯, toward 灯, lighting and other, it in safety process in important function. combined front in 整辆车 front 部, it main/primary lighting and function. manufacturing 车灯 材 material need tool has good resistant impact property, light property, weather resistance, easy processing property and other property can, lamp covers generally using/adopting PC or 者PMMA材 material, base/seat generally using/adopting ABS材 material.

         remove outer also value attention/notes is, plastics advantages obvious, in machine cover/cap, 尾门以 and and other cover/cap parts and 底盘附 parts and other positive 呈现出 expand large use plastics trend.

         ratio 如2000 year rear, plastics in USA, 欧盟以 and Japan market has rate already 逾90%, inner due to Knowledge and and other causes, this ratio/proportion need low more. from already 经出台 《车辆燃油箱 use standards 》(GB18296-2001) 看, metal also is engineering plastics 油箱, need combined standards can market, this technology upper plastics already to 国家认 can, plastics in automotive upper application scope 也进一步 expand large.

        结语: automotive light amount trend 越发明晰, plastics in automotive decoration upper use add 广泛. although plastics in automotive outer upper application future also has very long need 走, is in add lower, has versus this field/area also new development high 潮.
