thermoplastic property plastics injection molding molding this type of methods is will plastics material melt, rear will its film 腔. melt plastics 一旦进入 mold in, it cold mold cavity molding formed 一定形状.  

        形状往往就 is most rear formed product, in or as is most formed product use front again need other processing. many fine 部, 诸如凸起部, 肋, 螺纹, can in injection 模塑一步操 as in molding 出.  

　　 injection machine has basic parts: used for melt and plastics mold injection plant/unit and clamping plant/unit. and plant/unit function in 于: 1. make mold in 承受住 injection pressure lower combined; 2. will products injection plant/unit in plastics mold front will its melt, 然{HotTag} rear control pressure and speed degree will melt mold. currently using/adopting injection plant/unit has types design: screw 式预塑化 device or di grade plant/unit, and 往复式 screw. screw 式预塑化 device utilizing 预塑化 screw （第一 grade ） again will melt plastics 注入注 material 杆（第二 grade ）.  

　　 screw 预塑化 device advantages is melt material quality 恒定, high pressure and high speed, and injection amount control （ utilizing active 塞冲程两端 machine 械止推 plant/unit ）. this long is transparent, thin products and high production speed rate need. its disadvantages non-uniform time （导致材 material degradation ）, relatively high equipment use and repair use.  

　　 most commonly used 往复式 screw injection plant/unit need 柱塞即 will plastics melt injection.
一,
thermoplastic property plastics tool has add hot soft 化, cooling hard features plastics. day active in use large separation plastics belongs to this 范畴. add hot soft flow, cooling hard, this type of process is can 逆, can 反复进行. polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), polyoxymethylene (POM), poly carbon acid 酪, polyamide (PA), acrylic type plastics, its it polyolefin and its copolymer, poly 讽, polyphenylene oxide (PPO), chlorine polyether and other is thermoplastic property plastics. thermoplastic property plastics in resin separation 子链都 is type or belt/tape structure, separation between chemical generate, add hot soft flow ． cooling hard process is material 理变化.
　　 thermoplastic property plastics also can again separation is use plastics, use engineering plastics, high property can engineering plastics and other type.
　　 main/primary thermoplastic property plastics has polyethylene (PE) （PE ）, polypropylene (PP) （PP ）, polystyrene (PS) （PS ）, polymethyl methacrylate (PMMA) （PMMA, has machine 玻璃 ）, polyvinyl chloride (PVC) （PVC ）, nylon （Nylon), polycarbonate (PC) （PC ）, polyurethane ester （PU）, PTFE （特富龙, PTFE）, polyethylene terephthalate (PET) (PET, PETE) and other.

二,
injection molding, thermoplastic property plastics injection molding, this type of methods is will plastics material melt, rear will its film 腔. melt plastics 一旦进入 mold in, it cold mold cavity molding formed 一定形状.
　　 形状往往就 is most rear formed product, in or as is most formed product use front again need other processing. many fine 部, 诸如凸起部, 肋, 螺纹, can in injection 模塑一步操 as in molding 出.

its understanding is “旋转式铸模”, is what 也查不 to, 也不知道英文翻译应该 is what

this is Magis very more year front technology, 就像我们现 in injection molding, fast speed molding technology also is price 昂贵, also very more type made 一样, this also has China injection molding processing 厂.
