       film molding is will in extrusion machine in plastics melt 经T type extrusion, 直接进入 water solvent liquid or cold cooling, rear made film. this category of processing made can 够充实 阐扬 by processing material property can, meanwhile also can most good dimensions degree. large large thermoplastic property plastics film can use method production. for semi crystallization type thermoplastic property plastics add combined 适.      
　　平 film extrusion molding is: will in extrusion machine in already 经塑化 uniform plastics melt from film machine extrusion, cooling 辊接触而 cooling solid 化, most rear formed wide degree film, formed 卷. film structure can therefore for or separation 歧毛病称, 当两层 film between viscous property can 欠安时, need in between 插手一层 very thin adhesion 层, front hot property can and viscous property can.         
　　 used for film and film extrusion machine has types type 式, 即 more runner extrusion machine 头, belt/tape material block extrusion machine 头以 and more runner machine and material block combined 共 extrusion machine 头.          
　　(1) more runner extrusion machine 头: 由数台 extrusion machine extrusion melt from 一 存 in more runner machine material separation 袂流入 setting wide degree and thick degree separation runner in, melt in machine type inner composite/compounding molding. using/adopting this category of made can selection property and melting point versus relatively large plastics raw materials made composite/compounding products. composite/compounding 层数不 can more, 否则共 extrusion machine 头 于 complex.         
　　(2) belt/tape extrusion material block machine 头: 由数台 extrusion machine extrusion melt material block separation runner, process its inner melt rate ratio agent and thick degree agent agent, rear combined 进入衣架 machine extrusion molding. this category of made 答应人们 production relatively more composite/compounding film, extrusion machine small 巧而慎密. its short 处毛病 is has property and processing temperature degree plastics dry composite/compounding, processing relatively narrow.         
　　(3) more runner machine and material block combined extrusion machine 头. it is Germany Reifenh妘ser company 斥 专门 use processing above hot property material material extrusion machine 头.
