in injection shot molding technology already toward is decrease/reduce molding product thick and increase molding 时 模穴数, therefore injection shot molding machine need has non high amount, this high efficiency 塑化效果, 均质化 and fast speed injection shot and can and positive machine design. plastics product 定义“ thin parts ” this project is its flow long degree and /壁 thick ratio value (L/T ratio) (its thick degree 以1mm 说)至 less need large 于150时即称 is thin parts. is improve/increase injection shot molding efficiency, reduce thick is reduce material consumption or is large small already, most important is need reduce molding 时 循 ring time, thick can decrease/reduce semi, cooling time will can drop to 原 需 25% time. high speed rate for/regarding need relatively high pressure, warpage decrease to most low, clamping force requirements reduce is has 益, high injection shot speed degree can let molding product generate most small force: 一方面 can improvement molding product quality, another 一方面 molding product dimensions can 早一点 stability but also surface temperature degree still high can 早一点进行托模. thin parts design by in packaging box/case 也逐渐 application to product upper, thin parts production use is high amount, high precision type plastics injection shot molding machine. thin parts product can separation formed type: 1. high 容积 此 type thin parts product in selection most injection shot molding machine is its high amount, its product is more fast speed molding parts formed: 杯子, 花盆, various dimensions 桶子, food container (例如人造奶油 or color packaging container), usually material use PE or PP less PS此 type material product thick 介于0.3~0.4mm. for/regarding more 模穴 injection molding parts mold (例如96模穴 above) in processing use high injection shot rate (to 650mm/s above)并搭配 high color pressure (to 700bar above), this micro small product in dimensions density need ratio in color color uniform property quality requirements more important. 2. high precision type high precision injection shot molding product main/primary slip sheet/plate, CD box/case, magnetic sheet/slice cover/cap 子, use product (诸如 has cover/cap 子 培养皿 and other. this product requirements important requirements upper especially is in dimensions and warpage, slip sheet/plate, CD box/case need in molding rear 进行组配. this product thick degree 介于0.4~1mm间不 is versus thin, its injection shot rate (to 350mm/s above) and pressure (to 600bar above) ratio packaging container is low, in material selection upper use PS, has use engineering plastics 诸如ABS, usually use in mono parts upper. 3. high high precision type product for/regarding plastics injection shot molding machine more need demand in 容积, density upper, type product action electrical outer housing/shell, machine outer housing/shell, its it use equipment and office electrical and other gas equipment, product thick 介于0.2~1mm, use material is flow property 差 诸如PC, ABS, PC/ABS mixed combined also use PA, PBT or LCP is material connectors, 端子台, its it thin parts product also large 体积 部 product, 诸如: electrical machine, machine, table/sheet machine, machine and other outer housing/shell. has thin parts molding this technology for injection shot molding machine requirements has lower 几点: 1. high can force: use large dimensions screw 并搭配复螺纹, can relatively high 塑化容 amount. 2.良 good 塑化效果: generally remove will add material speed degree slow 以获致良 good 塑化效果 outer, use 复螺纹亦 can same 效果. 3. fast speed injection shot: thick parts, parts, thin parts molding its injection shot speed degree generally 介于150~1000mm/s, molding product and plastics features 而定. use pressure device provide to speed degree requirements necessary property, another fast speed reaction 伺服油 pressure 阀 达 to speed from 0~800mm/s. 1. high injection shot pressure: high injection shot pressure is is and high L/T ratio or non thin thin parts molding. 2.平顺 且花费 short machine as time: machine as 动应该 is 平顺且 fast speed 以节省 molding time. 3.敏感 and has injection molding parts mold measures: injection molding parts mold safety plant/unit in design stage/phase provide can 靠保护 measures, 包括开关模时 safety measures and safety. 1.稳 solid machine and rigid strong/high sheet/plate: is fast speed and high pressure, add upper thin parts or fast speed molding need solid machine machine base/seat and sheet/plate, anti injection molding parts mold deformation. 2. can more heavy function: 同步处理 function can has 效 节省 molding time 此部份包括讯号同步处理, di as and other. 3. low can consumption: can tube/pipe 理首先考虑 in application 方面(包括 thin parts and fast speed molding use) can formed 效, is different machine equipment in can consumption upper has different. reduce thick can 节省材 material consumption and molding time, but also provide versus more cost machine 会, in many can use thin housing/shell molding product by 估计, production will can this technology competition advantages will 会越 越 obvious. 转自一点通 injection molding parts 网
