di color injection molding, is will types different color plastics 注入同一 mold molding methods. it can make parts 出现两 types different color, can make parts has 规则 图案 or random 则 云纹状花 color, improve/increase parts use property and property.  
(1) di mixed color injection molding  
    di mixed color injection molding principle. it has material 筒, material structure and use and injection molding material same. material has 各自 通道 and nozzle versus 通, in nozzle in also has 启闭阀2,4. molding 时, material in material in by good rear, 由启闭阀2, 4 control material nozzle rear and material ratio/proportion, rear nozzle injection mold cavity. can to various mixed color different plastics products.  
 
di mixed color injection molding principle
    1— nozzle 2—启闭阀3— material 筒 4—启闭阀 5— material 筒

(2) di injection molding principle  
      is di injection molding principle 图. it has material 筒1 and 5, its nozzle structure has 特殊, it remove has usually nozzle function outer, also can 由安装 in rear gears 3 belt/tape 动旋转. molding 时, material 筒1, 5 in separation 别塑化 different color color material, gears 3 belt/tape 动回转轴4回转, make different color color material 交替进入 mold cavity, from to in toward 四周辐射形式 different color and plastics products.

  di color injection molding precautions due to di color injection molding is material in  
      mixed combined in molding, therefore, this 自于两 material in material must has good combined strong/high degree, is ensure has relatively good combined strong/high degree, 应当尽 amount use different color types plastics. use different product types plastics di color injection molding 时, must 先进行结 combined property can experiment/testing, 确认结 combined combined rear can start production, 否则, combined strong/high degree good types plastics mixed combined in 一起, easy make parts cracks and other defect.

di color mold
　　 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,于 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.
　　1.母模 两 形状 is different, separation molding 1 types product, 而公模 两 形状完 full 一样.
　　2. mold front, rear in 心旋转180o rear, must combined. design must this 检查动 as, for 模架定位 processing requirements relatively high.
　　3. 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.
　　4.三 sheet/plate water most good can design formed can demolding as. especially need attention/notes soft water demolding as is can *.
　　5. 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?
　　6. 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.
　　7. 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.
　　8. 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.
　　9.两母模 and 公模 运 water 布置尽 amount separation, and 均衡, 一样.
　　10.99% 情况 is injection molding product hard separation, again injection molding product soft separation. is soft easy deformation.
