Shanghai Daoqin Plastics Co., Ltd.

随 终端 use for product appearance requirements improve/increase, electronics electrical appliances parts in structure upper more add complex 而体积 upper 也不断 toward small type development. precision injection molding technology in this 方面就发挥 heavy large function, injection molding technology large large improve/increase precision plastics parts quality, can property, property can, reduce production cost, and improve/increase production efficiency, tool has separation important 意义.

　　 precision injection molding technology is injection molding processing development 推波助澜

　　 injection molding processing technology is manufacturing plastics products types methods, will melt plastics utilizing pressure plastics products mold in, cooling molding to need various plastics parts types technology. currently most use plastics is polystyrene (PS). 据国际 mold and plastics industry supply 商协会 negative 责人罗百辉 introduction, 随 “3C” product development, precision injection molding machine as is precision injection molding key/critical basic equipment, in molding products dimensions heavy degree, inner in quality and heavy degree and molding efficiency and other 三 方面都 to large 改进. versus ratio injection molding equipment, precision injection molding machine true positive for/regarding products control and precision production. precision injection molding plant/unit is improve/increase quality, injection molding heavy degree and products inner in quality and other 三方面 key/critical parts. currently, plant/unit main/primary toward achieve high speed, high pressure and fast speed target/goal development.

　　 polyurethane ester foaming technology more good property can more low cost

　　1965 year Germany Sonderhoff company and BASF packaging company achieve reaction 密封垫 理念. 1980 year, foaming molding （FIPFG, FormedInPlaceFoamGasket）密封 technology 诞生. one-time achieve mixed combined in 待密封 工 parts upper 游走, will separation mixed combined material coating to parts in 创举. 1992EDF company launch belt/tape has MK200 mixed combined di separation system DM110. this rear generate 第一 接头密封 foaming project.

　　 in 近20 year in, polyurethane ester foaming technology （FIPFG）经 不断 development, already formed is types formed industrial process, 不断 应 used for machine 柜, packaging material, electronics industry, automotive industry 密封. industrial 自动化 飞 speed development, 现场密封 technology in automotive industrial and its sleeve/set production in 发挥 越 越 important function, and 逐步取代 molding seals （即冲 pressure molding parts or strip/profile 状橡胶 seals ）. currently this equipment already widely used in 发达国家 industrial and machine production, in inner already 经进入 部 separation machine 柜, automotive, aerospace and electronics enterprise, polyurethane ester foaming technology its can substitute/replace large advantages 逐步占领密封 market, tool has large market outlook/prospects.

　　 in injection molding process high efficiency, high density cost relatively low development lower, Europe plastics market will 视角定位于 mold welding, inner 联密封以 and micro molding most new in. Germany 胜德孚（Sonderhoff）三 month in Germany development new Mold’n密封 process. polyurethane ester foaming molding technology （FIPFG） expert Sonderhoff营销总监彼 菲舍尔告诉记者, system separation formed injection molding machine control system, as is inner system Mold’n密封 process, system especially innovation features in its is 一 6轴 machine used for remove separation and 密封材 material application PUR. in stage/phase, molding process hot decrease/reduce solid time, “ in Germany Lossburg示范 改 injection molding system, in remove and application 程序时 use 约45秒 time, in rear for FERMAPORK31 polyurethane ester soft foaming system 密封三 separation can full 治愈, very long time balanced belt/tape. ”彼 菲舍尔说.

　　 in mold manufacturing industry, 不锈钢 mold production Germany Edelstahlwerke（DEW）2010 year launch Euromold meet/satisfy more processing can force need, 不锈钢 mold in more 腔PET preform mold increase more 达192腔.

　　威猛巴顿菲尔一直 active in other application development in, micro metal plastics mixed combined separation molding, packaging technology development and generally metal strip/profile production 经营. new micro rate machine can very good formed is 一 完整 production manufacturing, 由overmoulding to 卷筒纸 metal strip/profile thermoplastic property plastics, 如LED引线 frame project mono 元 一部 separation. cycle is 5s时, company 声称, 跟传统 injection molding process versus ratio, can to 节省30至50％ cost 目.

　　 polyurethane ester foaming technology more good property can more low cost

　　 generally, used as precision injection molding screw material tool has very high rigid degree and strong/high degree, made precision injection molding screw according to processing material different different. is improve/increase injection molding long ratio, most large degree reduce products molding shrinkage rate, precision injection molding machine injection molding pressure can to 216～243MPa, ultra-high pressure machine injection molding pressure can to 243～392MPa. in this type of lower, screw must tool 备足够 rigid degree and strong/high degree, can in high pressure injection molding 时不会出现 bending and and other phenomenon. another, for/regarding 传统 肘杆 plant/unit clamping plant/unit, its 动, sheet/plate between method obtain long stability degree, meanwhile very difficult achieve for precision mold low pressure 保护.
