1． di color injection molding machine sleeve/set structure, specifications full same injection plant/unit formed. nozzle production methods need its has structure, or has can 旋转换位 structure full same molding mold.

塑化 injection 时, requirements sleeve/set injection plant/unit in material temperature degree, injection pressure, injection material amount and other process parameters same, need amount shrink small sleeve/set plant/unit in process parameters 波动差.

2． di color injection molding plastics products and injection molding plastics products comparison, its injection 时 熔 material temperature degree and injection pressure need using/adopting relatively high parameters value. main/primary causes is di color injection molding in mold runner comparison long, structure comparison complex, injection material flow retardant force relatively large.

3． di color injection molding plastics products need selection heat stabilized property good, melt degree low raw materials, 以避免因熔 material temperature degree high, in runner inner time relatively long separation understanding. application relatively more plastics is polyolefin type resin, polystyrene (PS) and ABS material and other.

4． di color plastics products in injection molding 时, is make types different color material in molding can very good in mold in 熔接, ensure injection molding products molding quality, using/adopting relatively high material temperature degree, relatively high mold temperature degree, relatively high injection pressure and injection speed rate.

传统 di color injection molding mold has “凸模平移” and “凸模旋转”二 types 形式.

① “凸模平移” mold has 二 凹模 and 一 凸模. material 筒射胶时, and 第一 凹模闭 combined. formed types plastics injection. types plastics solid rear, 凹, separation 开, 由第一 types plastics formed semi formed product in 凸模, 并随凸模一起移动 to for 准第二 凹模 位置. injection molding machine combined rear, material 筒进行第二 types plastics injection. types plastics solid rear, injection molding machine mold, 取出完整 products.

② “凸模旋转”形式 di color mold has 两 凹模 and 由两 背 for combined formed 凸模, this is can 旋转. di injection molding machine has material 筒, material most good is design in injection molding machine direction direction. can meanwhile injection types different plastics. 当射入 二 types plastics solid rear, injection molding machine and ejection products. products rear, “ can 旋转凸模”转 180 degree. injection molding machine combined, lower 一 循 ring.

due to “凸模平移”模式 第一, material is injection, 而“凸模旋转”模式 第一, material is meanwhile injection. therefore, product, use “凸模旋转”模式 production efficiency is use “凸模平移”模式 production 2倍.
