Shanghai Daoqin Plastics Co., Ltd.

      in front upper, is outer trim parts （如保险杠, sheet/plate, 车轮罩, sheet/plate and other ）, inner trim parts （如仪 table/sheet sheet/plate, inner sheet/plate, table/sheet sheet/plate, material cover/cap, base/seat 椅, rear sheet/plate and other ）, also is and structural parts （油箱, dispersion hot device water 室, device 罩, 风扇叶 sheet/slice and other ）, can to plastics made parts 影子. 今朝, automotive upper 100kg plastics material 庖代 蓝本需200～300kg metal material, decrease heavy lower non 常突出, this for/regarding can 源, drop temperature gas 体排放存 in important 意义. automotive plastics gas tube/pipe replace metal can decrease light quality 40％～60％, 且概况 light 清勾当 retardant force small, can front 进筹谋 machine property can, in front 进焚烧 efficiency, drop consumption, decrease drop 噪方面都起 to 必定浸染. statistics, automotive use plastics product types already 达几十 types, uniform automotive plastics use amount already automotive heavy 5％～10％, automotive light amount formed long requirements and automotive plastics expand large as, automotive plastics mono use amount rear also will 会进一步 growth.  
    automotive use plastics separation is types : types is hot solid property plastics, it can 够遭遇住通俗 烘漆独霸; types is thermoplastic property plastics, in processing light easy, fast speed benefits. in use plastics in, front 7位 plastics material product types and ratio/proportion large is: polypropylene (PP) 21％, polyurethane ester 19．6％, polyvinyl chloride (PVC) 12．2％, hot solid property composite/compounding material 10．4％, ABS8％, nylon 7．8％, polyethylene (PE) 6％.
    plastics is its 广泛操 as step/link. plastics can process machine solid, bonding or welding 进行毗连. solid speed degree fast, combined used for has plastics, can is high, generate force in, can formed 密封接头 or obtain property can. bonding can obtain property can and 精良接头, 但独霸坚苦, need 精心肠进行接头 and made 备, but also speed degree very slow, 不适于 more amount amount production. welding 经济, 简略, fast 捷, 靠 住, can formed strong/high degree 濒临于母材 接头, is combined used for more amount amount production, in automotive obtain 愈 愈广泛 操 as. plastics welding 手艺程 degree already formed amount automotive production 手艺程 degree and new material 斥 程 degree table/sheet 记标帜之一.  
    automotive 财产各 type plastics welding made  
    plastics welding 局限于 thermoplastic property plastics welding, due to has thermoplastic property plastics in add hot can melt or soft 化, hot solid property plastics add hot can soft and heavy 熔.
    hot 风焊濒临似于 metal oxygen gas 焊, rear use front use hot gas add hot. hot gas process in, 自焊枪 in hot gas 流(范例 temperature degree is 200～300℃, speed 达15～60L／min) meanwhile for filling rod and parts add hot, material soft to 黏稠状态时, filling rod pressure to in. filling rod material and formed separation 不异, is is (直径约3mm), welding thick sheet/plate using/adopting more welding. filling rod short 处毛病 is in more process in bubbles light easy in in, formed strong/high degree drop 落, this issues issues can process using/adopting 三角形截面焊 rod solution. can use hot welding plastics polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), has machine 玻璃, polycarbonate (PC), polyoxymethylene (POM), polystyrene (PS), nylon, ABS and other. hot gas important benefits is property (矫捷 property) strong/high, can use 简略 便携式 equipment processing large type, complex parts. hot welding combined used for 犯警则 structure, it speed degree slow, welding quality very large degree upper 依托于独霸者 手艺, very less used for amount production, it combined used for 修理独霸.  
      welding in automotive industry in requirements
1. for welding parts dimensions degree high: is 保障产 material 拆卸精 degree and dimensions property, 请求尽 can can decrease thin sheet/plate parts in front degree and rear hot force and deformation;  
2. for 焊缝接头 property can high: welding 接头不 mono need meet/satisfy and force property can indicators, but also has low waste property can 请求;
3. for amount welding production material high 且一致 property good 请求;
4. for welding production process high 节奏, high efficiency 请求;
5. for 零毛病舛误 quality made and 保障, 提出 主动化 welding process and 信息化打点 请求.
