Shanghai Daoqin Plastics Co., Ltd.

         di color injection molding is 一 部 parts use types plastics injection molding achieve.

        广义 di color injection molding 包括overmolding, through injection molding machine, injection molding achieve.

        狭义 di color injection molding is utilizing di color injection molding machine, will types different plastics in machine injection molding formed parts, Common is 旋转式.

         front for equipment requirements high, is production efficiency low lower, basic suitable for requirements high degree soft, hard types material molding, rear suitable scope/range and product quality good, production efficiency high, is currently trend.

        1.1 requirements

         di color injection molding for material must meet/satisfy basic conditions, bonding versus and processing process versus 容. in addition, also must meet/satisfy below/following requirements:

        (1) injection shot mono 元, 平行同 toward, for toward, water and 垂直L type, Y type toward mono injection shot structure;

        (2) mixed combined 射嘴, 花纹, 波浪, flow marks, 渐层, and other 特殊射嘴;

        (3)夹模, standards type, 垂直转盘式, water 平转盘式, 转轴式, machine 械手转动式 and other machine 构;

        (4) add material, remove standards pressure 马达驱动 outer, also has ESD(ElectricScrewDrive) electrical add material structure;

        (5)油路, has ACC蓄 pressure high speed injection shot and 闭回路 design.

        1.2 features

         property can strong/high energy saving high: injection molding machine energy saving renovation rear, system can fast speed 响应, injection molding machine can according to need for to fast speed adjustment, can has improve/increase injection molding machine electrical can utilizing rate, from to high energy saving.

         stability property good: system is pressure and amount di ring control, according to injection molding machine demand injection molding machine to. system in to 定输入 or outer dry function lower, can in short adjustment process rear to new balanced 状态, or 者回复 to has balanced 状态.

         fast speed property good: fast speed property is system quality important 标志之一, due to production process time short, generally in 200ms以 inner, is achieve ultra- 调 requirements, requirements process front 沿陡, energy saving renovation rear upper rise rate need large, injection molding machine to 1500转 time to 0.03秒.

        精 degree high: renovation rear degree is 指输出 amount can 跟随输入 amount 精确程 degree. electrical machine using/adopting magnetic technology, 准确, speed, electrical machine using/adopting PLC technology, control more 精确, 允许 偏差 generally in 0.01～0.00lmm between.

         energy saving: using/adopting system, reduce power/electricity 消费.

         improve/increase efficiency meanwhile reduce cost: to high 响应, high heavy property, improve/increase speed degree stability property; using/adopting 2 types raw materials or 2 types color can meanwhile molding, large large decrease/reduce process and force from achieve cost; parameters setting, system adjustment is non simple 数码操 as.

        1.3 di color mold features

         di color mold: types plastics material in 同一台 injection molding machine upper injection molding, separation molding, is product one-time mold. generally this type of process di material injection molding, usually sleeve/set mold formed, need di color injection molding machine. di color mold currently market upper day 益盛行, this type of process can make product appearance more add 漂亮, easy color can use spray coating, 但造价昂贵, technology requirements high.

        母模 两 形状 is different, separation molding 1 types product, 而公模 两 形状完 full 一样.

         mold front, rear in 心旋转180 degree rear, must combined. design must this 检查动 as, for 模架定位 processing requirements relatively high.

         front sheet/plate add A sheet/plate thick degree can less 于170mm. fine this type of Model/Grade injection molding machine its it data, ratio 如, most large thick degree, most small thick degree, KO孔距离 and other.

        三 sheet/plate water most good can design formed can demolding as. especially need attention/notes soft water demolding as is can *.

         in design 第二次 injection molding 母模时, is 避免二次母模插(or scratch)伤第 one-time already molding good product 胶位, can design separation 避空. is must heavy 考虑每一处封胶位 strong/high degree, 即: in injection molding in, is has in large injection molding pressure lower, plastics deformation, 导致第二次 injection molding can can has generate can can?

         injection molding 时, one-time injection molding product dimensions can large, make it in 第二次 molding can and 另一 公模 pressure more 紧, to function.

         attention/notes in 第二次 injection molding 时, plastics flow is 否会冲动第 one-time already molding good product, make its deformation? if has this can can, need method improvement.

         in A, B sheet/plate clamping front, need attention/notes front slip block or is 否会先复位而 pressure bad product?如此, must method make in A, B sheet/plate clamping, rear front slip block or 斜顶才 can 复位.

        两母模 and 公模 运 water 布置尽 amount separation, and 均衡, 一样.

        99% 情况 is injection molding product hard separation, again injection molding product soft separation. is soft easy deformation.

        2, di color injection molding material

di color injection molding material combined property understanding

        3, di color injection molding 案例

         益于 di color injection molding machine product tool has more design advantages, currently already by 广泛运 use in machine 业, made 笔业, automotive 业, home appliances 业, tool and day use product and other more field/area
