        一, plastics features and machine precautions

         various plastics raw materials features different, machine need to types material features, can time, and plastics 变质.

         plastics product types for plastics features methods

        PS hard 胶, heat stabilized property good, in molding temperature degree lower relatively long time hot 也不会 separation understanding, therefore machine will electrical hot 关掉即 can

        ABS hard 胶, heat stabilized property good, in molding temperature degree lower relatively long time hot 也不会 separation understanding, therefore machine will electrical hot 关掉即 can

        PE, PP soft 胶, heat stabilized property good, in molding temperature degree lower relatively long time hot 也不会 separation understanding, therefore machine will electrical hot 关掉即 can

        PC due to production 暂时停顿(如夜班不 construction start), make material 筒一直 maintain in 160℃ left right, 以免胶 material 受潮, need material, need PE清理 material 筒, 并取出 screw, use copper 刷清理 screw

        PVC hot property material, machine front 先关闭 electrical hot, rear PVC launch, to material temperature degree drop to 150℃ rear, most rear use PP, PE and other heat stabilized property good plastics material inner plastics full launch

        PMMA in relatively high temperature degree lower easy separation understanding, in positive molding temperature degree heat stabilized property good, machine 时 需关闭 electrical hot.

         nylon PA此 plastics heat stabilized property good, machine front 不许清洗 material 筒, need 立刻关闭 electrical 源, 否则15 separation rear plastics 会变质

        POM此 is hot property plastics, machine in electrical hot front 10 separation pressure low, rear material inner plastics launch, material 时, use soft 胶清洗.

        二, types material color

         for 同一材 material color 时, amount color is concentrated color material, from transparent material is transparent material relatively easy as 业, color 程序如 lower:

        同一材 material color process

         from concentrated color is color, from transparent formed transparent material 时, 空射十数次 rear,

         color still pure 净时, lower 射嘴, material 筒缸头清洗

        三, types material more 换

         thermoplastic property plastics in temperature degree high 状态会 viscous metal 面, temperature degree low viscous, material function utilizing features, make more 换 材 material viscous material inner 壁, cold screw high viscosity material 削取之

        异 types material more 换

        四, meanwhile more plastics and color

         in 此情况 lower, selection types features plastics and add 入清洗 agent use, generally agent has: screw agent, and other.

         meanwhile more plastics and color

         if in this type of lower will material 筒清洗 dry 净, lower 射嘴, material 筒缸头清洗, has necessary must lower screw 清洗.
