more color more separation injection molding parts method MulticolourandMulticomponentInjectionMouldingENGEL(英格尔)Combimelt模塑 is manufacturing or production mono 元 若 dry types parts combined formed more function parts. it application color 效果, will different material features versus combined. assembly and other combined adhesion methods already 经体现 in process in. this is product production has 意义 节约潜 force and new design can can property. 一, ENGELCombimelt模塑 method formed 1, injection molding parts machine 　　　　　 2, mold 　　　　　 3, process 诀窍　　 4, equipment and 自动化 formed sleeve/set solvent understanding equipment full world already has ENGEL company use Combimelt模塑 method manufacturing 500 more injection molding parts machine, 200 more sleeve/set mold and formed sleeve/set production 线. lower 面我们 use 例子说明 this type of injection molding parts method advantages. 　 二, more color color method for/regarding manufacturing control and belt/tape 符号 仪 device sheet/plate, more parts, more color injection molding parts method still is types has methods. not only is due to quality causes, high wear resistance, but also is due to causes, can and machine printing or light 刻标记 versus comparison. this type of methods already in more color automotive 尾灯玻璃 product in more year more to 证明. 　 三, rigid property / flexible parts through rigid property and flexible polymer bonding, used for and retardant 尼 组 separation can 直接注入仪 table/sheet outer housing/shell and parts surface. is improvement or increase surface scratch force, can in table/sheet 层注入TPE, formed soft/flexible 层. assembly upper small, soft/flexible has elastic property parts from overall in separation usually is difficult, this is is viscous in but also dimensional stability low. positive is due to this causes, use Combimelt, in production in can flexible function parts and dimensions stability parts adhesion, but also in more 数情况 lower, use Combimelt more but also production equipment more can 靠. due to 几何形状 causes, 由PP made formed 杯子螺纹 cover/cap and TPE made formed and surface using/adopting method in ES2500H/500K2F injection molding parts machine in manufacturing, 35秒 is manufacturing cycle. mold upper belt/tape 螺纹, mold upper belt/tape 螺纹, 由同步移动 machine 械操纵 plant/unit 进行预模塑. 　 三, plastics -橡胶 coupling agent mono adhesion parts 橡胶- metal adhesion parts use product design using/adopting thermoplastic property material and hot solid property manufacturing adhesion parts already has good more year. however, use coupling agent manufacturing adhesion parts can ensure in adhesion upper 传递 必需 force. in application coupling agent and process front, this type of methods disadvantages is price 贵, surface treatment 费时, but also, in rigid property parts in 注入橡胶 cost very high. new development plastics -橡胶 adhesion parts has this type of disadvantages. many standards adhesion parts tool has good thermoplastic property, 例如: PPE or PA, has use coupling agent 共硫化. advantages is production, but also has ring 境. use coupling agent housing/shell 体时, 不会发生 solvent understanding. plastics -橡胶 adhesion parts will 代替橡胶- metal adhesion parts. this in that requirements weight light 且腐蚀 important field/area, in automotive industrial in especially 理想. 四, 3D injection made electronics sheet/plate Combimelt used for manufacturing electronics sheet/plate parts. manufacturing methods several 方面: 继承 几乎任何开头 electronics sheet/plate need electronics and machine parts; make product small type 化; mono 一组装 structure, machine parts. inner already 经知道, this type of new methods technology 术语3D-MID is 三维模塑 inner parts shrink 写. in metal 化 模塑 parts in injection 基面, make electronics 线路显露 in upper. 第二步, electronics between 空隙. and electronics between has 0.3mm, using/adopting high flow property material is can achieve. 接, in used as electrical metal plastics surface electroplating, 例如镀镍 or copper, and other by using/adopting metal. 　 五, can 卸接头 模塑 assembly in Combimelt more application combined, application material between need has high adhesion force, molding type process in manufacturing industrial in production can 拆卸接头. selection 适当 材 material is can in mold in achieve. relatively 链, ring and other, need machine assembly, in injection molding parts machine upper can production product. methods, use molding production 婴儿橡皮奶嘴 手 ring. 第一工位预注入PA手柄 ring, rear mold, overall 指针盘转180, 插入一根 new and used for 注入PP联接 tube/pipe mold cavity. tube/pipe shrinkage in 紧密配 combined molding ring upper. ring tool has function 位置, 像一 铰链一样, 允许 手 ring front rear 摆动. this type of methods tool has 一 附 add advantages, this 样 联接不会脱开, from safety degree 证明也 is has 利. 　 六, parts 共注模塑 method 举例说明, using/adopting 共注模塑 method manufacturing 无皱纹, and foam high quality surface thick 壁层状 parts is can can. this type of injection molding parts method 越 越 more to in thin parts manufacturing in application. 例如: 头戴反 light 镜, tool has internal film 房子. in this application in, application is high hot dimensional stability or electrical rate as is active property filling material 樗, parts table/sheet need meet/satisfy surface quality requirements. 当今 政治 policy has made increase this methods 兴趣, and 芯体材 material heavy again utilizing. thick is 0.9～0.6mm different type parts research already table/sheet 明, it and parts 几何形状 complex property has 关, 芯体材 material density can in 35 and 65％ between 变化. 例如公园椅 扶手柄 in di in, use SAN做 table/sheet material, density is 55％ PS foaming material 做芯体共注 manufacturing, manufacturing cycle is 60秒. 摩托车油箱 螺帽 in 6腔, 3扣形 sheet/plate in add pressure screw demolding injection molding parts manufacturing, 12秒 is manufacturing cycle, parts 由油箱清洁 rear HDPE回炼组 formed. thick is 0.9mm, 芯体材 material 占容积 65％. 　 七, film products design and material selection 取决于 adhesion strong/high degree material adhesion surface upper 传递 拉 force and obtain adhesion strong/high degree below/following factors effect/influence: material selection; process methods; process control; products 几何形状; adhesion surface design. 　　Combimelt method adhesion mechanism main/primary 基于预模塑 一部 separation again rear, types material and adhesion surface 接触, and this material in thermally conductive property 差, usually 熔接仅仅 in parts surface deep degree small 于0.1mm处 generate. 　　熔化不 generate thermoplastic property material that chemical 联接, polymer/macromolecule material material 理联接边界层 adhesion strong/high degree is can 靠. parts in is 不适宜 情况, 此时, using/adopting 切口（ or 预模塑 孔） machine adhesion formed outer add can 靠联接, this 样, parts 间 联接就 can achieve. 　　例如, use 一 做拉 force experiment/testing parts various material adhesion strong/high degree experiment/testing, for/regarding 检验者都 is very has use. lubricant and demolding agent has types function. composite/compounding and strong/high degree to process control effect/influence. injection speed degree effect/influence 流体工 as temperature degree and gas property 改变. meanwhile, rigid property material injection in flexible material upper, adhesion force relatively high 时, use low melting point material. upper due to deformation and 跟随而 mold issues, this is can can. light slip adhesion surface is has 益. coarse adhesion surface can increase surface 积, 但两元 parts surface 势必会存 in gas, 常常会 reduce adhesion strong/high degree. 　 八, methods according to product amount and products 几何形状, 实践证明Combimelt模塑 method in processing process in has lower types methods: method; method; 　　　 separation degree method; 　　　 slip block technology; 　 共注 film method. method is through 一 输送 plant/unit in 同一台 injection molding parts machine upper 预模塑 parts to mold cavity. this is large type more color or more separation products in large type upper heavy type mold 习惯做 method. in 两台平行排列 standards injection molding parts machine using/adopting plant/unit 传送预模塑 products is can can. 当发生几何形状 retardant again 次插入模芯时同样 can 采取转移 method, other methods suitable. 　 转盘 method is formed sleeve/set mold semi in 旋转, 而保留 in in 预模塑 parts by to semi solid mold new in 预模塑 parts by to semi solid mold new mold cavity inner. this type of methods advantages is: mold design simple, is is machine belt/tape 一 组 parts; injection molding parts machine upper can meanwhile production several mold, separation utilizing 转台. in this type of lower, lower 一模塑工位 design need different and mold cavity 几何形状. use separation degree 盘 预模塑 parts high, 并旋转. separation degree method advantages main/primary is design more 自由. method, method and separation degree method features is has mold opening and type need demolding 处理. is reduce mold cost, using/adopting slip block technology can in mold in production more color or more separation parts. in this type of lower, types material mold cavity by sliding strip/profile or 芯模隔离, in types material injection molding parts formed rear by 打开. 图6例举 this type of technology types application, poly 硫橡胶 made formed frequency box/case magnetic belt/tape. clamping force fast speed 释放, slip block 返回原位 rear, can formed transparent 窗状开口, 而不需打开 mold. 　 slip block technology function principle: A, slip block toward front production 预模塑 parts; B, in 不打开 mold lower, slip block 返回原位, 注入第二 types bonding material formed made parts. use slip block technology 14秒 is manufacturing cycle, can made formed poly 硫橡胶 belt/tape 窗状开口 声 frequency box/case magnetic belt/tape. 芯材进入 still in flow 预注入 table/sheet material inner 并取代 it 位置, 但并没 has 充满整 mold cavity. already solid table/sheet material has by 取代, 并包住芯材. most rear in remove nozzle and maintain pressure stage/phase, table/sheet material by used for remove nozzle and maintain pressure. from nozzle 孔排出 芯材/ table/sheet material mixed combined material must injection absorption. 1, injection table/sheet material 　　　 　　　　　　　 2, if time very 紧 话, can table/sheet material and meanwhile injection 　 共注模塑 配 for material must meet/satisfy basic versus conditions: bonding versus 容; 　　 processing process versus 容. processing process versus property evaluation and to: uniform expand dispersion 芯材组 separation process 说明, temperature degree and separation material viscosity. in products in, made parts 几何形状 for material distribution also very important effect/influence. in pressure has for 称 几何偏差都会引起芯材 不规则 distribution, formed lower effect/influence: in flow 区域形 formed table/sheet material, in 塑流尾流开口 or in more runner products in; formed function and adhesion parts, strip/profile and other, material surface poly 积层一旦穿透, surface melt is can 移动. 　 九, mold design ENGEL mold manufacturing company manufacturing Combimelt mold, in field/area in already has 25 year experience. mold design is in and machine engineering 部 紧密 combined as in achieve according to manufacturing engineering Technikum or 顾客定购 machine requirements in Combimelt injection molding parts machine upper mold testing and most adjustment. this small inner more 数模塑 application is 由ENGEL company design manufacturing. below/following is 另一组 has use mold. Combimelt一 sleeve/set sheet/plate mold using/adopting method manufacturing 出 1100 mono parts. sleeve/set mold is is production automotive inner outer design made as, belt/tape has white 符号 预模塑 parts is using/adopting light POM made, tool has function. mold rear, outer black PC材 material injection in white 预模塑 parts upper. light parts 由接触 sleeve/set, assembly parts and light sheet/slice formed. 预模塑 parts and outer is through high hot system 注入. 　 is production automotive plant/unit, tool has function 锁体就 is sleeve/set hot solid property bonding parts, design belt/tape 44 mold cavity Combimelt mold. in mold cavity in use PPE production 锁体, rear use separation degree 盘/转盘模 锁体插入第二 mold cavity injection molding parts device and SBR橡胶 made formed 密封圈. 共硫化 function ensure most bonding property, is use coupling agent. 硫化橡胶 elastomer need 170℃ mold temperature degree, 此时PPE tool has very good dimensional stability. is design this type type mold, not only need tool has more parts mold structure Knowledge also need has mold design Knowledge. this for/regarding cold technology, mold add hot and in high mold temperature degree lower 调换元 parts selection assembly is non important. 　 injection mold is according to mold principle made formed. in technology amount in can 够发现 mold inner 差别, adjustment 不希望 has separation distribution: in made parts table/sheet 层区域 heavy injection molding parts can decrease/reduce distribution non-uniform; local adjustment inner thick degree and solid parts amount 闸; mold inner amount 闸（ table/sheet material flow mold sheet/plate, slip block or 芯模移动 限 made, meanwhile stage/phase, in most rear pressure mold cavity inner 插入移动插 sheet/plate ）; runner technology, 例如: selection in runner 末端 溢 runner parts, can 预先采取 anti table/sheet material poly. more cold runner material system and 传统 模 pressure versus 似, has 进胶口 system, 如注胶口, belt/tape separation runner system multiple thin 模进胶口, belt/tape 针尖进 material system 通道注胶口. can 采取传统 hot separation runner system, is is in separation runner system in need table/sheet material and mixed and.
